The Cal-look Lounge

Hi,

I guess it's my turn to write a short story of my project, with a couple of pictures...

As some of you may know, I started a chassis car project two years ago by buying Leif Nyström's old car (without engine & transmission).

[attachment=1]

The original plan was to replace the body with an all-steel oval-window body. I found an early '53 oval window in the summer of 2008. I believe it is a very special car; from what I can see from the picture, even though it was built 3/1953, it has split window doors and grooved trim from the factory. My guess is that they used some old parts at the factory?

[attachment=2]

I stripped the chassis and the body

[attachment=3]

and did a mock-up of the car

[attachment=4]

Dam, has it started to snow in hell? A Fin making a project thread  :o

Looking forward to your updates. Love the heading, it`s long between purpose built street cars  :)

Some time passed by and in late summer 2009 I was doing some work on the car, and somehow started to re-measure the chassis. Ooops. some of the tubes were undersized and it was illegal for racing in Finland. I was more or less forced to divest the chassis and go for a new one. A pity, since the chassis had served Leif well, running hi 8s at 250km/h++

I contacted RLR, and we specified the new chassis; CrMo chassis with a Funny Car cage (SFI 25.4, 7.50sec), ladder bars, K&L beam...

[attachment=1]

The chassis was shipped in late January

[attachment=2]

During the shipping I prepared the body and axles ready

[attachment=3]

[attachment=4]

The container arrived in early March

[attachment=1]

And the same night I had bolted on the axles and wheels

[attachment=2]

[attachment=3]

The following day I put on the body

[attachment=4]

The 10" wheels barely fit inside original fenders - there ain't too much space between the tires and the valve covers, but the engine fits behind a closed deck lid

[attachment=1]

I had a 70mm narrowed beam available, but I need to narrow it more, prob 6"

[attachment=2]

The rear apron had to be cut to fit the oil pump

[attachment=3]

The contrast between grooved semaphores and Funny car cage

[attachment=1]

A street car with a SFI sticker

[attachment=2]

A special picture for Richie  ;D

[attachment=3]

And the car on scales. My estimate is 770-800kg race ready with driver, it is a full steel street car after all  ;)

[attachment=4]

Awesome! Looks stunning  :o

Wout

Looking really good!
What engine are you putting in?

Holy crap!

 :o >:( :D  As long as they stay there thats ok ;) :)   

Jyrki,it looks really good,like that the decklid closes properly,what offset & sizes are the wheels? 

cheers richie

Man, there are so many cool cars being built all over Europe right now. I am so glad to be a part of it.

Very very nice Jyrki!!

Wow, what a racecar Jyrki!  :o 8) Thanks for sharing!
I`m on my knees now and pray that this is the car you are bringing to SCC this year  ;)

Hi,

I can't even dream of driving it this year, probably not even 2011. Even though I have sold 2 1/4 cars during the past 2 years to be able to focus my limited time&money for this project, it'll take a couple of years to get it running, maybe more. I don't have a timetable for it, but I must admit I am anxious. This year my goal is to run my '65 beetle which has been woken after 4 years of hibernation.

Turbo engine, most likely the Pauter engine that I had in the '55 in naturally aspirated form.
Wheelie bars for both cars Richie, unless Kalle arranges Unlimited Street Europe  8)
The wheels are Billet Specialties (cheapest SFI 15.1 wheels), 3½" front with 1.75" Back Spacing, and 10" rear with 3½" Back Spacing. 10" is overkill, but this is all about "look & feel". Axles are 5" narrowed.

Jyrki

That carage and the vehicles that it contains seems familiar... 8)

Looking good, Jyrki - Thanks for the updates and info!

Just AWESOME,great lookin' car you are building.Keep going on.
 ;)

Wow, a 3.4 litre turbo monster? That should be able to move this thing on the streets for sure. It looks like a tight fit for the exhaust pipe on the 3/4 side but surely you will manage  :)

Unlimited Street Europe, now that would be a lot of fun;

1) cruise
2) race
3) BBQ
4) Bragging

how about adopting the US rules?

 
•   Any four cylinder, air cooled, rear-engine VW powered vehicle allowed
•   Minimum vehicle weight (with driver) 1700 lbs (can be changed)
•   Must have two front seats
•   Must have functioning headlights & tail lights
•   No Wheelie Bars allowed
•   Proof of Registration and Insurance Required
•   Vehicle must have all required safety equipment for ET/MPH as per NHRA Rules
•   Vehicles must complete an approximate 20km street Cruise prior to the event
•   No tow vehicles allowed (Vehicle must drive to the Starting Line and return to the Pits under its own power.)

Just for fun!

Sounds perfect! Count me in.

Jyrki

Truly awesome car you are building there Jyrki
Keep up the good work,

Now thats sound PERFECT - I want in  ;)

Awsome project Jyrki,can't wait to see this car finished-love those wheels! :P

Stian

Cool project!

I remember seeing your green oval pauter powered monster at SCC a few years ago, and i think you won an award too, right?
That car had some serious punch, and turbocharging it just sounds insane  ::) ::) ::) ::)  ... in a good way  ;D

I loved your green car! very cool.

All of a sudden I feel the urge of building my ragtop back to racetrim hehe

I want to play to...

Sounds like a cool class that I would like to be in if at all possible  8)
How much 'aircooled' are you talking about Kalle? Cylinderheads aircooled? intercooler aircooled?

(awesome build too Jyrki!  :D)

Aircooled, just to make sure Skinne does not dominate the class  :)

On a more serious note, this is something I have been talking to Jyrki about over a beer or two and nothing more serious than that. But if there is any interest for it perhaps I should take it further?

Sorry for going off topic in your project thread Jyrki.

Best rgs
Kalle

Zowie Batman!

Awesome project!


Keep the pics coming!

Minor progress on the car...

I built a new 6" narrowed front beam, and now the wheels fit the way they should:

[attachment=1]

The chassis and the body are attached together with temporary mounts. There is still some adjustment to be done; at the moment the body is 2mm off-set.
With 28" tires the stance is close to what I had in mind:

[attachment=2]

It is a very tight fit to get everything "inside the car"; the header and oil-pump vs. rear apron, intake vs. deck lid, injectors, wheels, valve covers vs. rear tires etc. As an example, I had to cut the rear apron for the #2 exhaust primary pipe, but the deck lid still closes:

[attachment=3]

I also started fabricating the header. The pictures are even worse than the ones above, so I won't include them. Anyway, the turbo will be located next to the transmission nose cone / behind the co-driver's seat. I am aware the tubes are pretty long, but I really want to locate the turbo, IC, tanks, battery etc as much as possible to front/right/down to optimise the center of gravity. I hope the turbo will spool up w/o problems, it is a moderate size turbo on a big engine.

20% done 80% to go?

Inspiring stuff.

This gonna be a fantastic car!

Time for a little update before I put this project aside for a while. The season is about to start and now I need to focus on the '65 ; I really want to drive it at last (it's been too long...).

Anyway, I did some stuff on the '53. There was not enough room between the valve covers and tires:

[attachment=1]

There was 13mm extra space inside the valve cover, so I chopped 10mm off.
Nice welds (not mine):

[attachment=2]

Now there is enough room:

[attachment=3]

I started the header:

[attachment=1]

The turbo's preliminary (and unconventional) location:

[attachment=2]

---

This is where I will leave the project for a while, or at least as priority #2. Now the focus is on the '65 that I have had for more than 20 years. It has not been on the road since 2005, but there are some upgrades since the last time out...

[attachment=3]

Nice work Jyrki,hope to have a look in May.

Time for a new update. After the season I did some stuff with the '65 and then started to work on the '53 again. Not much done yet, the header, exhaust w/ muffler (yes, there is one), dual wastegates, some panel work and rust issues, and with the help of Matti Ä the stance is now correct and there is enough ground clearance and room for the 28" tires. At his pace this will take years...

[attachment=1]

[attachment=2]

[attachment=3]

Next steps will consist of some final body work / details, and then take it apart and start building the floors etc.

Nice to see some progress.Looks AWESOME   :o

wow !  :o

Terrifying!  8)

Looking perfect!

Here are some detail pictures.

Engine mock-up. There is no room for a fan shroud, so the plan is to run E85 and some big efficient electric fans (and a 100 amp alternator). Hope it will keep the head temps when cruising in the pits (or in the streets?).
[attachment=1]

The Garret GT40 and the muffler (I know it will be loud, but there are classes that require a muffler, but without noise limits):
[attachment=2]

Then a  picture of the Funny Car cage. The safety rules do not require one before 8.50sec, but I feel that with a VW Beetle it is good to have some extra protection:
[attachment=3]

As far as the "look and feel" of the car goes, the plan remains; it will have full trim, running boards, windows fitted with original weatherstrip (not flush), lights and dash, everything except for the bumpers. The color is not decided yet, but at the moment I am leaning towards original "Sahara Beige". I think it would be a nice sleeper color.

Jyrki

Nice car and good to see you got a complete chassis from ronny  :) . so you can be shure it runs save and straight .
If you would go on the street in germany with a car like that they take you to law  :(

Udo

That stance looks awesome, good work!

 :D...that was what I was thinking of by reading the topic!
"Something wrong officer?"

What a cool project! I like how the exaust dumps out the side, reminds me of a orange 40 willys that was on the cover of street rodder magazine a million years ago.

I think the word "street" can be interpeted in many ways...

Hi .

Maybe the fist streetcar with M&H Winter DOT    ;D ;D

Cool project,

.

Some progress: custom parts thanks to my friend Pekka.

The dual cell for the fuel, and the water that is circulated thru the intercooler:

[attachment=1]

Then there is the liquid intercooler; as big as I could fit so that (in theory) it is still possible to have some room for a co-driver:

[attachment=2]

As you can notice, I am trying to locate them with Center of Gravity in mind, and I don't mind the weight.

Jyrki

Looking fantastic! This is going to be one car to watch out for in the future 8) Matt

Long time, no update. How is the car progressing Jyrki?

Thanks for asking, it has actually progressed pretty well since the racing season ended. The chassis has almost all brackets tigged, and is painted (a temporary paint), and the body is ready for paint (satin paint job for now). With a new car I acknowledge that there will be modifications, so the plan is to run the car for a while, and take it apart later for the 'final' paint etc.
Front beam, steering, fuel cell, battery, shifter, seat, window net, pedals, header, oil tank, IC etc done. Next things to do: floor & firewall, intake manifold, plumbing, wiring, engine and transmission assembly and a million little things. I hope to be able to get the car out for some initial tests during 2012.
Jyrki

[attachment=1][attachment=2]

Thanks for the update Jyrki. The car is coming along nicely I see :-)
I remember you talking about a theoretic chance of fitting a passanger. Must be interesting to sit there leaning on the turbo and having the intercooler betwen your feet :-D

Yap, there will be a passenger seat for cruising purposes, but the passenger is not gonna travel comfortably. The extra seat and other not-so-necessary details are the last things on the ToDo list.
Jyrki

Car is progressing...

[attachment=1]

Welding the driver's floor (spec calls for a steel floor for the driver).


[attachment=2]

Sahara beige!!! The guy who painted it didn't want to do a half-ass-job (i.e. satin paint). Me like :)

Jyrki

Nice  ;D

such an awesome car, can't wait to see the finished product!

very nice project...really like the big tyres in the back, nice stance...

Looking good,if i had known you were painting it shiny I would have sent some yellow,its not alot away from beige apparently ::),in the picture of the floor welding why is he doing the passenger side? did you flip the negative when you printed it from the camera film  :D


cheers Richie

This will be the car to watch this season. The first 8 sec street car (AC).

Looking good Jyrki!!

/H

very awesome build... ;D keep up the work.....and pictures ;D ;D

Good thing you didn`t forget AC.  :) Let`s see what happens when Skinne drains the water from his car.

There you go kalle I corrected it for you :o :D

cheers richie

And it's not even a cabrio - what was I thinking  ;)
Jyrki

 :D :D

Its not to late,its easy to swap the body still,you want me to find a donor and yellow for you and send it over,I think I have a slightly scratched one still ;)
On a more serious note,are you making the inner front fender area from steel as well? I read a build thread on the Red victor3 FIA Pro mod car and they did it as the rules for them required it,I am thinking of doing it as it looks like it offers alot more protection to your feet if the worse happens 
cheers Richie

The SFI 25.4 requires 0.6mm steel floor only under the driver, so I cut all other pieces out of 0.8mm aluminum. There are quite a few bars around the driver, but what you're saying makes sense and I will reconsider.

Jyrki

O.M.G. :o

Some progress...

[attachment=1]

[attachment=2]

Still a long way to go...

Jyrki

NICE  ;D


Will this race at SCC? :)

Hi Jyrki,

Missed your build up till now ::)
Very impressive, look forward to seeing it out 8)
Cheers
Kev

Yes! Looking great.

Wow, that thing looks awesome! :0

Very, very  8)

I am not too optimistic about racing at SCC this year. I have a lot of things still on the ToDo-list. Also, the Finnish FHRA tech div visited the garage two days ago, and they suggested a couple of changes to the car to make it safer.

Yesterday I picked up the last parts of the body from the paint shop:

[attachment=1]

and the manifold built by my good friend JP:

[attachment=2]

Jyrki

Pure porn

It doesn't get any better than this!  :o

Awesome work but knowing you personally for long time, it's sort of something to expect 8)

just loving this build

Jyrki,
looks beautifull,what will you do to allow for engine expansion trying to pull the intake apart?as it is will it expand a similar amount? or will you have some sort of connectors to allow for this movement?

cheers richie

Beautiful build Jyrki! And refreshing to see the use of a real tube chassis and still sticking to the street car title... safety first.
But looking at that engine, I get the feeling that the streets are really short in Finland? Or how do you solve the cooling? 

This build is so 'Luftsick'  ;D
I'm loving it!!

Hi,

The manifold is not done yet, it's not even fully welded yet. My initial idea was to cut the other side runners, and use silicone hoses and clamps to allow movement. Just like in every previous turbo engine. However, I might take the risk and install it as is; the sidewalls of the plenum allow some movement, and the temp/growth of the long block vs. intake is unknown. If needed, it is VERY EASY to cut it later (unless I brake something first  :'(). The watercooled Subaru has a 1-piece intake.
So, not decided yet.

There will be electric fans, and fuel is gonna be E85. Not sure if the fans are gonna do their job. Back in 2009 I had this engine in N/A setup (11.8:1 compression) on E85, and with type 1 cooling, fan rpm slowed 40% from original, I could not get the heads above 120C. At WOT you cannot keep it cool no matter what you do, but that is just X seconds at time. In the street (city, not highway) and pits it's just cruising at idle. We'll see (there will be oil and cylinder head temp sensors).

Keep the comments coming - it's easier to solve possible issues now.

Jyrki

ive been using wigins clamps on the inlet side of things, they allow a lot of movment and are so easy to break the joint for servicing etc.

http://images.importtuner.com/reviews/parts/0702_impp_09z+wiggins_clamps+tube_connectors.jpg


I find they work great always seal up and can be used on air or liquids. from memory you can have about 5mm in expantion and 10 DEG of movment.

I use them all the time, i find buying the clamps and sealing ring from ebay and then i machine the ferrals myself ( i make them for some chassis shops)


Hope it helps.

Cracking Build by the way ;)

martin i found sime clamp that work better than them you show.

try vibrant performance they are stronger, but they only go down to 2,5" diameter. i use the on pressure side of turbo.



But Nice build jyrki

just looked them up, very nice

the main reason i used the wiggins ones is that there used on aircraft, so i kind of figured they would hold togther ;) lol

Absolutely STUNNING!

Just AWSOME!  ;D

Never seen a thing like that before.......thanks to exist. :o

Some progress..

Got the plumbing done

[attachment=1]

and the intake welded and anodized

[attachment=2]

Then it was time to assemble the engine

[attachment=3][attachment=4]

Next tasks: weld a few more brackets, finish welding the charge pipes, clean all tanks, hoses etc, assemble and check for leaks.
The biggest single task ahead is wiring (quite a few sensors around the car). Then another million little things...

Jyrki

keep it up

Tomi borrowed scales from Mika (THANKS!) and we weighted the cars. The new car is 752kg with driver and all tanks full, but still missing the full steel body, windows, wheeliebars, chute and probably something else too. Weight race-ready estimated to be around 880kg + possible new ballast (now the ballast consists of only the 31kg battery tray in front of front axle and 12kg of lead next to the fuel cell).
The weight distribution is estimated to be appr. 57% rear – 43% front thanks to the location of a number of heavy components: IC, tanks, batteries, turbo etc.

[attachment=1][attachment=2]

Tanks and hoses cleaned and tested for leaks (had to fix a transmission oil leak), all fluids are in, pushrods and rockers installed. Next: bleed brakes and clutch, wiring harness…

Jyrki

Excellent
so three weeks today we will see it loaded on the trailer heading for norway? :D

Making good progress

cheers richie

Nice! Just found your thread. Great work. This is going to be one bad a$$ car.

Just waouw !!! Amazing build Jyrki !!  :o

......I am Stoked..!!  It is "AMAZING" to see such craftmanship and innovative design... The Euro community as a whole baffle my senses with their incredible sense of direction with build outs but THIS BUILD really is COOL..!! My hat off to you for your time and patience and inviting us into your world since the beginning. This is MY Dream car and will no doubt pop out eye balls where ever you may appear. Beautiful garage setting with everything clean and organized. Beautiful craftmanship and wishing you success on your completion and hope to see you and your "street car" while in Europe next time in 2013..?    "Thanks" to you again for your efforts, and for a cerebral awakening/LOL...   Dyno Don

That's a real nice weight distribution. Well done!  8)

Matt

 Hi there Matt, congrats to YOU as well for sharing your build and awe inspiring pics.  You guys IMPRESS me......   Dyno Don

Thanks for your kind words Don ;)
Matt

Some progress.

Windows have been cut (though they will be assembled with chrome trim):
[attachment=1]

Some interior parts:
[attachment=2]

And finally, I fired the engine 2 weeks ago, and earlier this week I ran thru gears on stands and did the first test drive - 10 meters in the garage  ;D
[attachment=3]

Still a few tasks on the ToDo-list before I can take it to dyno, and weather permitting, to a test drive outside. I am not too hopeful about the weather, it is +2C and has been raining a lot, and in northern parts it is already snowing  :(

Jyrki

Love it!
Thanks for updating us on the progress. Easy that this will be (is already) one of my most favourite cars of all times

Looks amazing. Plastic windows on the street?

My kind of test run! Looks stunning Jyrki.


Yes, it`s fully legal and certainly a lot better if you ever crash. It takes hours to get rid of all the glass after first getting rid of the bits in your eyes.

-BB-

Very nice Jyrki!!  :o

Actually I'm not sure why I was surprised we had plastic windows in the red car and that got street usage.

Nothing beats a garage test run  ;D

It looks like you will be done for the next Turbo Town Shootout. I am almost certain it will be a really fast race. Need to get some T-shirts ready for the historic event.

As Kalle said; safety first. Lexan is legal for racing and street here. The windshield is laminated glass though.
Jyrki

Awsome Jyrki !

This thing is absolutely bonkers, I love it!  Awesome work!
Matt

This one vill be mean when it´s finished. Can´t wait to see it live.
As Ragtop said, next Turbo Town Shootout would be fine. ;D

Nice work mabey a movie of 10 meters in the garage? ;D

Hi Jyrki, it seems that your garage is exactly 392,34m to short  ;D!!

Good brakes?

Next step was to drive the thing a little more. We got some snow late last week, and the temps were close to zero Celcius, so had to find a place with electricity so I could heat the oil before the test. Without any body over the chassis the police might have some comments if I would drive it around the block?

Loaded the thing on trailer:

[attachment=1]

Took it to a parking garage, and plugged the oil heater.

[attachment=2]

Then it was time for a cruise. Taking it really easy, just testing that the controls work as they should, and confirming the sensors that are already there are ok. Found out a few issues; first of all the Fuel Pressure Regulator does not raise Fuel Pressure as it builds boost (brand new big Aeromotive FPR). Then the Vertigate needs some more final adjustments. Otherwise it was all good (or as the Slugs say "it didn't burn or anything").

[attachment=3]

Thanks to Jukka & Marko,

Jyrki

 :D  :D  :D

Hahaha... next step, fit studded snow tires and take it for a drive on the streets. BTW, the Aeromotive regulator probably freezed up... its not built for arctic temperatures  :)

Keep on with the good work Jyrki and I really look forward to seeing you back on the track again. Kjula and Turbo Town Shootout I hope?

Best rgs
Kalle

I like this line

"Found out a few issues; first of all the Fuel Pressure Regulator does not raise Fuel Pressure as it builds boost (brand new big Aeromotive FPR). " The sound must´ve been awesome in that garage.

Great stuff :)

that car looks awesome even without the body fitted.

i think you'll need a new speedo though as the 120 km/h one will only be sufficient for garage driving and not street driving as you intend...

What's your second small battery for? Looking killer!

You must have had soooo much fun while running it underground ;D
Awesome project!

There isn't physically room for an alternator in the car (belt-driven by pulley), so in order to secure voltage I have a converter which is fed by the red Optima, and the converter deliveres 15.6V to the electric system. Starter has a dedicated battery, because the converter would be on the limit with the starter's amp draw.

I have a plan how to fit an alternator in the car, but let's see first if I could get away without.

Jyrki

I tried running without an alternator on mine,

when i looked at the logs, the voltage used to drop to 9.8v at the top of the RPM scale, then on the drive back to the pits it would come back up to 11.9v

Cars looking awesome!

Well done!

Martin

Hi,
The converter is supposed to keep voltage at over 15V as long as there is decent supply - the main battery can drop to 10V and the system still has 15V. Let's see if the converter lives up to the promise of the marketing material. I am logging also the supply voltage.
Jyrki

Do you use a 'Kennebell' voltage booster for that Jyrki?

No, it's just a 12 VDC / 16VDC converter, supposed to live under rough conditions, 70A continuous, 120A momentary.
[attachment=1]

Jyrki

Nice, didnt know you could get one.....

Remains to be seen if it works in real life or not..
Jyrki

Report from the dyno two weeks ago:

[attachment=1]

The plan for the first dyno session was to test the engine, transmission, electrics etc, and only run at modest load, then take it back to garage and check the motor and transmission oils, oil filter, valvetrain and leakdown before reaching for any real power, so we ran on 0.5bar wastegate springs only. We started with short sweeps at 15-30% throttle opening 1500-4000rpm, then moving up. The ‘small’ Garret GT4094R with a/r 1.19 exhaust made 0.5bar boost by 3500rpm with less than 40% TP, making it a nice street engine  ;) The exhaust back pressure stayed at the same level as boost, but I wonder if the turbo will be good for 7000rpm and 1.5bar?

One of the reasons to go to dyno is to find new-car-issues, instead of finding them at the strip. First issue was a slipping clutch at little over 4000rpm, but during the following pulls the clutch started to hold, so it just needed to be seated in. Then there was an issue with the electric throttle going to fail safe on two pulls – it’s a duplicated signal and there was prob too big difference between them (more than 3% triggers the fail safe). It didn’t happen again but this needs to be figured out. Then while running up to 5500rpm, still running at less than 50% throttle opening, the fuel pressure dropped by 0.5-0.7 bar between 5100-5400rpm. We checked the electrics without finding anything, so figured it must be something mechanical. We didn’t have much time left, so just called it a day.

BTW, the 12V to 15.6V converter did its job all day.

By (unfair) comparison, the new engine made more torque with just 0.5bar boost and <50% throttle than the old 2332cc street engine did with full boost and full throttle (the one that ran 9.43 in a 900+ kg street car) on the same dyno  ;D

Back in the garage I drained the oils and checked the oil filter. Engine oil was somewhat milky (running too rich with E85, oil temps below ethanol boiling point even though it was connected to the heater). Otherwise everything looked ok.

Then I took off the fuel filters (100 micron S/S pre-filter and 10 micron cellulose main filter) and disassembled them. The pre-filter had some soft stuff in the mesh (and I also found out that the design is restrictive), and the main filter looked ok. However, the stuff in the pre-filter resembles the cellulose material of the 10 micron filter? This is a very likely the reason for the drop in fuel pressure.

Next steps: new fuel filters, clean the injectors just to be sure and a new dyno session at some point. Still A LOT of little things to be done with the car...

Jyrki

Nice work, I love the design of that dyno.

Dear Jyrki

As I also had a lot problems with alcohol in the oil  :P and tried different thinks on preheating, I wanted do ask U about your preheating set up.

1. Power of the heater?
2. where is it installed?
3. what temperature setpoint?
4. do you have circulation during preheating?
5. how much oil do you have?
6. how much drops the temperature when U start the cold engine ?

MeXX

Very impressive stuff Jyrki ;). I would be over the moon if my car ends up half the quality yours is. ;D ;D

Michael

1.   300W. It is enough to heat the oil in the oil tank in a decent time, but….
2.   oil-tank, which holds 50% of all oil
3.   none. There is a timer in the electric supply, or alternatively it is ON all the time
4.   nothing automatic. I sometimes circulate w/ starter engine
5.   about 9 litres
6.   if I heat 50% of oil to 70-80C in 20C garage and start the engine, the oil temp drops below 50C once the heads have reached 70-80C

Maybe I should add another heater element in the engine case oil sump (there is prob 2 liters of oil ??)??

Jyrki

looking fantasic,

Nice to know the voltage converter is working.

Nice!

Whoohoo, the new wheels arrived some time ago, and with the help of Tomi, Sami and Make we got the windows installed and lifted the body over the chassis.
The wheels are 8½x15 and 3½x15 Fuchs replicas (5 x 4 3/4" bolt pattern, custom et, custom lug nut setup) from Image Wheels (http://www.imagewheels.co.uk/index.html). I am really happy with their product and service! 5 weeks from initial query to delivery  ;D

Loving those wheels and made about 2 hours fom me :) very nice, and your car is dam cool too :)

It's getting BETTER and BETTER,love it!!!!!
 :)

That is badass, one of the coolest builds on this forum  ;)

That came from the guy with the other one :-)
But yes, I totally agree:-)

Are this the original steel fenders and the tyres are 10,5 x 28 ?
Please,do you have pics from the inside of the fenders.
Great car,thanks Fredy

Hi Jyrki,

I love this thread- one of the most awesome VW builds I have seen in a very long time. Great engineering and attention to detail.

Just as an aside, now that you have changed your wheels, if you ever think about selling on those Billet Specialties Street Lites, I' d be very interested in buying them off you. Just a thought.

Cheers,

Jonny.

Just 25 minutes from me! ;D

Car looks amazing Jyrki, subtle but insane at the same time. Brilliant.

Hi,
Yes, the fenders are original steel fenders. They are std width, or maybe even slightly narrower towards the rear of the fender. The tires are M/T 9x28x15, which in reality are about 27.3" tall. 5" narrowed, Geers brakes, 8.5" wheels with 3.75" BS. With this setup ideal back-spacing would be around 3.25-3.5".
I'll take some pictures under the fenders.
Jyrki

Thank you so much Jyrki !

Here are some poor quality pics of the rear fender tabs. The tabs are raised so that the Dzus' springs are not the first to touch the tires, just in case the car squats too much.

Then a picture of the stance (the front runners are not yet on the 3½" Fuchs replicas) :

And one more; almost everything fits under the panels. I had to take off the right side fuel rail; but it's an easy modification to make it fit.

Jyrki

Fecking awesome!

Good thinking on the raised tabs too!

Bad ass car, love it.

Absolutely awesome  ;D

wow, to faint !
Please one pic from the inside of the fender
[attachment=1]

Such an Awesome Project, Looks Amasing!

awesome pics...keep em coming

Wow. Just wow. I think this time Jyrki has really hit the gold vein for style. I have to say it's one of the coolest-looking VW rides I've seen in a very long time, if not ever. WAIT...what...it goes fast too? Even more amazing.

The motivation for our hobby is built on cornerstone cars like this: they come few and far between but this is one of them.

I totally agree with previous speaker.

Awesome work Jyrki, I really like you style build a "Streetmachines"

VERY cool and getting better with every update!

I love the aggressiveness of the wheel placement at the front wheels, great stuff Jyrki!
Happy new year btw!  ;)

Thank You everyone for the kind words.
Jyrki

This is by far the most perfect beetle racecar ever! Just can't stop looking at it  :o
Never been a fan of raised rear fenders, but you made it perfect on this car! And those wheels!!!! Wow!

Hope you plan to bring it to SCC this year Jyrki, can't wait to see how it performs at the track.  8)

Very well put Sir  ;)

I think I've just had a crisis....that is a lovely looking car.

Great looking build!

Installed the Force sensor for Gear Shift Cut:

Jyrki

VERY VERY nice - Love the stance  :)

sha shwa shu..  Oops sorry, I was drooling :P

great looking car.
looks even fast just standing there.

henk!!!

The car looks great, but the LUTFISK stickers seem kind of fishy, Jyrki... ;D

And my good friends, the Arabia Slugs, said they had nothing to do with it :)
Jyrki

Some progress..

Wheel alignment a few weeks ago - thanks Takis

Corner weights

[attachment=3]

Maybe the 'Purpose built street car' should be re-named to 'Heavy street'?
With all ballast in the front, the weight distribution is 53% rear, 47% front. Only parts missing are the running boards and chute.

Jyrki

I have been testing the car at a truck terminal a few times. The gearshift mechanism was giving me a headache; combining American, German, Finnish and Australian parts proved not to be plug'n'play. The electronics seem to work, but the shifting mechanism did not. Had to take it all apart once, and in the latest test session it was better (though not 100% confirmed to work yet), but then new issues rose. There is a mismatch of parts with the starter which need to be addressed. On top of that I also broke two rocker arms. Everything in the valve train is the good stuff, and I though it was over-built. Well, my 'low-maintenance' junk needs some spares and I have to keep on working with the car. I was not expecting to avoid teething issues.

[attachment=1]

Jyrki

Good to hear that you are ironing out the issues. I have never seen such a nice part being broken, looks like new except for the obvious.
Hope to see you at SCC!!

I think there might be reason to suspect a valve hitting the piston when a rocker breaks like that. Hope that is not the case of course!

Russ used to break them once the springs were coming to the end of there life. the aggressive cam and floating took them out.


Martin

Your car is fantastic -- -- But you can either break those or bend these or break rocker arm studs or have the nut back off on the stud

I'm running into the same issue and can't figure out why -- been thinking I'm the lone ranger == very sorry for you, but I'm glad to hear that I'm not the only one, was starting to think that I'm crazy --- So my engine is coming apart

Leakdown measured ok. Everything was new when I started, designed for boosted application, and it has only seen very little GENTLE use. Well, these things happen. I will measure the springs to see if they are gone (they were fine after the 1½ naturally aspirated seasons, and in this setup they have only seen 6500rpm and 14psi boost).
Jyrki

Those are the older models. The new ones are much stronger.

That could actually be good news!
Thanks,
Jyrki

How do you tell the old ones from the new ones Shagg

the new ones are bushless and bearing less... Ive had them in my motor for a long time.

they are honed to shaft size and are oil fed from the pushrod.

Mine have done a lot of work on the dyno and arnt showing any signs of wear at all.

Martin

They are also made of different aluminum.  ;)

Pauter have redesigned the shafts, they will be available in 3 - 4 weeks.

I placed an order for a new set Friday, and they shipped Monday. Pauter is always extremely quick to reply and help.
It will be less ratio and more spring. I am not worried about less valve lift - that is not the bottle neck for power in my motor.
Jyrki

agreed! But is there a bottle neck or is it just a mark on the boost knob that says ( danger, over power.  Dont go past here! ) LOL!

Rocker picture remind me an old saying tells :)

If it's not broken you not try hard enough

Beautiful and impressive car...

looking good

Good luck on your 1st runs!

I guess it is time for s ahort report from BRC in Tierp and SCC in Gardermoen. Well, first a few words about the preceding tests. After installing the new 1.4:1 rockers in place, I took the car to yet another test at the truck terminal. The valve train seemed to work, and taking it easy the gears shifted without drama. It was Friday evening and there was a race for Fords the following day in Alastaro. I tried to call someone in the club, but no luck, so we just took the car there in the morning and at the gate asked if we could join the event with an old VW. They said yes. So I took the car to a strip the first time. Leaving off at idle, running at 0.8bar, granny-shifting at 6000 rpm, the car ran 12.x at 190km/h. Felt pretty ok, just a slight pull to the right. I had changed the rear coil-over springs and could not do another corner-weight, so that was the most likely reason. Took a look at data at the pits, and everything seemed to be in order. So for the next ‘pass’ I put on wheelie bars, messed something and could not do a proper burnout, and staged. There was no traction, it just went right to the limiter. Short-shifted to second, then third and then I broke the gas pedal. Whaaatt!!! I have burned 50 liters of E85, but I guess with the helmet on you just push harder ;) Anyway, fixing the pedal should be easy, so even though the car was not race ready, I still decided to take it to BRC and SCC for testing – I did not want to go without a car again. So I booked the ferries, corner-weighted and adjusted the car and fixed the pedal.
At Tierp I took the first pass really easy; same low boost, low rpm, granny-shifting, just like the very first pass in Alastaro. No slip in clutch, so it just spun the tires in 1st, but no issues in 2nd thru 4th. It did a 12.x / 203km/h, and went straight and easy. For the next pass I made some minor adjustments, but during the pass I broke the pedal again. What the %¤&%. In the evening I did a quick&dirty fix to the pedal using e.g. Richie’s old UK license plate as material. Saturday morning I went out again, but the pedal broke right away. That was it; the rest of the day I enjoyed watching others race in the really nice weather.
The next day we started to search for a new pedal so that I could take the car to SCC. I parked my trailer in Västerås for a few days before driving to Norway – thanks to the TurboTown folks for the safe parking place, hospitality, garage tours, cruise night etc! The Swedish Monday-night cruise had a thousand cars! Tuesday morning I picked up a new pedal from Stockholm (thanks Jukka & Tomi), and drove to Stian’s place where we modified and installed it, and did some minor work on Stian’s car – thanks to Stian and his family for hospitality!
Thursday I drove to Gardermoen, Friday we just took it easy and Saturday it was time for some drag racing. The track was a bit slippery, and even my low boost setup broke the tires loose in 1st, 2nd and 3rd as seen 04:32 on

www.youtube.com/watch?v=jPtomzYSdhg&sns=em

Sunday the track was better, but my pass was a disaster thanks to a charge pipe popping loose during the burnout – it did not build any boost at launch, nor during the run. It was an easy 10minute fix, but then came the rain. It was time to pack and drive to Stockholm and take the ferry back home.
In total it was a 2146km trip, a couple of aborted runs and only one run all the way down the strip. No good nor even decent time slips, but I was not even expecting that. Found and fixed a couple of teething issues and logged valuable data. Most importantly it was really, I mean really nice to see friends, hang out, watch and do some racing, meet new people, new friends. The hospitality was just overwhelming!!!
Jyrki

..and the story continues, including some more detailed technical shit.

For SCC my goal was 'to make a clean pass with 80% power'. Well, that didn't happen. It was not clean and there was no power.

After the Scandinavian trip I started to prepare for the next test session in the Finnish Finals in Alastaro. Based on what we learnt in BRC and SCC, and some further testing in a parking lot, I moved the ladder bar links one step up, softened all shocks and took some ballast from the front (now 962kg with driver). A new test at a parking lot showed it was better - with a third gear burnout I could get enough load on the engine to get an idea if the suspension setup changed, and check boost control.

http://www.youtube.com/watch?v=UbLE2Pa1XxU

Last Friday I took it to Alastaro. Tech inspection - OK. SFI 25.4 chassis certification - OK  ;D

First pass: bogged the engine really bad, down to <1000rpm. Drove thru the gears, granny-shifting at 6500rpm, 1.2bar boost. 12.1@215km/h.
Next pass: found traction, but 60ft was only 1.50sec. Later found the reason for that - I was pulling the shifter for a long time in 1-2 gearshift, so that the Gear Shift Cut re-activated and killed power. It also killed the 1/8" as it was doing only 168 km/h half track. The good news is that it picked 55 km/h from 1/8 to 1/4 :o Drove thru the gears, still granny-shifting at 6500rpm, 1.2bar boost. 10.2@223km/h. Car went straight as an arrow. Of course there is not that much power yet, but with reasonable amount of power I was so comfortable driving it that it was almost boring. This is good news - with the the previous car it took years to make it run straight.
Then it started to rain  >:(

http://youtu.be/qmUocsZy1hM

I would say this was '80% clean' and '80% power'. Still a lot to do with clutch, suspension, gearshifting, driver, power...

The time slips are not good, but I am reasonably happy with the progress. I have now 7 passes on the car, out of which one was aborted due to no traction in any gear, two due to breaking the gas pedal (?), and four passes driving thru all gears, taking baby-steps. 'At this age you don't have to rush things'.

Thanks to Alhomatic and Valtteri.

Jyrki

Great Report!

Is your shift cut on while you pull the shifter? as normally you set a time limit on the cut. So Pull shifter you get a shift cut for 0.2 of a second. then back to normal, even if your still pulling on the shifter.



Keep at it, its a stunning car! ;)


Martin

It activates for a limited time; I had it set for 0.10sec and then ramp power back in 0.02sec. There is also a setup for the minimum time between shifts for it to activate again. As I was pulling for a long time it re-activated. So my bad as a driver and as a tuner. I don't even need it now as I am using the clutch and lifting throttle..
Jyrki

you can teach the motec which gears your in, but using rpm against wheel speed. so it wont react.

have you seen the gear set on UAC? clutch less shifting? that system works the same a liberty box. you don't need a shift cut with it, just full power shifting.. only draw back I see is that you cant down shift.


Keep at it... ;)

I just have to say that reading this thread I thought I had an idea about what this car was about. I was fortunate to see it this summer, and make no mistake - it will blow your mind.
Perhaps the most well built "street" beetle in the world.

Will be looking forward to the rest of the story!

Yes, the ECU detects which gear is on. Can you please explain "using rpm against wheel speed. so it wont react".
In GSC I had the delay set at only 100msec, and no 'Next Gear Terminate', so I will address these.

Yes, I have seen the clutchless in UAC. What I have now is the Finnish Dog Ring stuff. With these you need Gear Shift Cut in a turbo car. Earlier this summer I fought with the shifting mechanism, and in order to get some passes this season I gave up and just started shifting with clutch & lifting throttle. I will continue the tests later - I really want to be able to do full power shifts.

Jyrki

Nice report Jyrki! Keep at it.

Season is over – here is the last report.

After the Alastaro event I took the car to dyno to see if there was power to be gained with more timing. Last year the engine was only dynoed to 0.5bar / 5000rpm before the clogged fuel filter ended the session, and the test passes this season were made with very conservative ignition maps. Well, we found out that the engine wanted a lot more timing above 6000rpm. What I had in Alastaro was less than 400hp to the wheels @6200rpm, and with more timing it made 450@7000rpm with the same boost. The numbers are not big, but less than 400whp was enough to run 223km/h at 960kg…

I made a small adjustment to the rear shocks, an adjustment to the clutch and registered to NIGHT OF FIRE in Kjula, Sweden. Boy the Swedes know how to arrange a nice event, with excellent atmosphere and lots of crazy Swedish cars  8)

First pass Saturday: 3rd gear burnout, launch @5000rpm & 1bar (same as previous pass in Alastaro): rpm dropped way too low to 3300rpm, so 60ft not good at 1.45sec. 1/8 mile 6.20/183, ¼ mile 9.61/230km/h. I would say speed is OK for the power to weight ratio, but there is still room for improvement in the et. I put it in neutral after finish line, and I let it coast along the very long braking area in Kjula, and I could hear noise from transmission. At the pits we analyzed there is something wrong in r&p area. The Mendeola case and r&p are 12 years old, but only maybe 130 passes?
 
The et is not yet something to mention, but it is going to the right correction. I would say I am now within half a second of the potential of current boost, and the car feels good enough to turn up the boost to 1.5bar.

I am ok to end the season here - a month ago the gap from actual time slip to theoretical et was 3 seconds and ending the season with that would have tasted bad  :(

Thanks to my Swedish crew, Johan & Fredde, for their help in Kjula!!!

Looking forward to 2014!

Jyrki

[attachment=1]

awesome car and another great report.

Interesting that the motor liked the increase in timing past 6000 rpm.

It's been a while...
During the winter I took the engine apart just to be sure everything is ok - it was - and Mr. Alhomatic checked the transmission. I also did a long list of smaller tasks on the car so that it would be ready for the first races. It was but I was busy at work, so I missed the May race in Motopark. Then there were no races on real tracks until now. So last weekend we took the car to Alastaro, and with the help of Kari, Tomi and Make, did a few more test passes. With the limited number of passes we could not get the car to hook, and it only ran 9.6/233 with a very bad 60ft time (1.55 spinning through 1st gear). Still on low boost  ;)
This was the first time I launched a chute. Naturally I would prefer not to have a chute, nor the wheelie bars, but I must say I will not run these speeds without one anymore. A 950kg beetle running >230km/h and small brakes definately benefits having a chute. Feels a lot safer!
Sunday rained out, so we will go out again to continue tuning the suspension.

[attachment=1]

Three more passes in the big race in Alastaro. 9.62, 9.52 and 9.41/234.9km/h. Still on low boost and still not 60-footing well (spins thru 1st - not hooking at all). I have now 9 'real' launches with the car in total. The car reacts in a logical way to adjustments, and runs real nice & feels good and safe. Just not hooking, and not much power. Need to do more work and tests with the clutch, suspension etc.
Jyrki

What tires / pressure are you running?

M/T 28x9x15, 0.75bar tire pressure, also tried 0.80 and 0.85bar. Tires are fresh.
Jyrki

Dear

Jyrki

Hope U are doing well and car gets faster soon. ;D
0.75 bar sounds much to me I'm usually runnin' 0,3 to 0,4. Yes I know my car is lighter than yours. ::)
Try go get pix if your tire works at launch (wrinkles) and it will hook up.

[attachment=1]
just 4 example. BTW to compensate my weight advantage I did this run with a passenger  ;D

DoD MeXX

What do you call 'low boost'? 20 psi?

I believe tire pressure is close to what it should be. Looking at the marks on asphalt it seems to use the whole contact width. The tires wrinkle too:

(http://miksu.1g.fi/kuvat/Drag%20Racing/FHRA%20Nitro%20Nationals%204.7.2014/Nitro%20Nationals%20042.jpg/_bigthumb.jpg) (http://miksu.1g.fi/kuvat/Drag%20Racing/FHRA%20Nitro%20Nationals%204.7.2014/Nitro%20Nationals%20042.jpg)

Yes, to me below 20psi is low boost. Last year I ran up to 1.2bar and now a little more (but not much). My friends from Västerås would say below 30psi is low boost  ;D

Jyrki

I'd say you're probably right! LOL!
Tnx, car is absolutely awesome!

If I remember correctly you have a better weight balance in your car than a typical vdub, meaning more weight on the front wheels and less on the rear. This should result in a different ideal angle to the ladder bar, I guess pointing "more down" in front.... I`m sure you have all this calculated and figured out, but wondering if you have tried a drastic change in the angle of the ladder bars just to see how it reacts?

Yes, different link points (Instant Center) have been in the agenda. We might even test going back to where we were (from 11" IC to 10" IC). At the moment I believe it is a combination of things; clutch, track, shocks, springs, suspension geometry, launch rpm and boost, power curve, wheelie bars, weight distribution, tire etc. Sometimes it's a bit tricky and the window is narrow. The data shows that the car reacts in a logical way to adjustments, and it is already a lot better than end of last season.
Jyrki

Dear Jyrki

I can feel what U mean! ::) It's always a combination of everything. I had to realize that the clutch is even more important than I thought before, and it took nearly a season to get a clutch that lasts and is smooth enough to make every launch the same. Then the adjustments got more comprehensible and more logic. Then it took many many runs but the ET came down.

DoD
MeXX

At what height is your center of gravity? You seem to push way below CG judging from the build images. How high does the link points let you go?

CG height is a little higher than crankshaft centerline & chute anchor point; probably typical to other similar cars. The car is most definately more nose heavy than the peers.
The highest link point is 11". If there was a higher point I would test it. I am not planning to go back to 10". Ladder bars are 34" long.

Last Saturday I took the car to Alastaro (Ford Nationals). The track was not prepped since the big race two weeks earlier. With some minor adjustments to the car (raise rear supension, 17kg ballast off from the nose, some fine tuning to fuel maps) it did 1.40 60ft, 6.01 1/8 mile and 9.36/231 (pulled chute early). Still spinning, still same boost. Next pass the engine did not run 100% clean (most likely Hall sensor fault) and it did 9.56/233. Again we learnt something, but not much  ;)

[attachment=1]

Next stop BRC Tierp  ;D

Jyrki

This is one of the best build lately!
LOVE this car!
Great work!

If you get frustrated ... just step back 10 paces and just look at it !!
its beautiful  ;D ;)

great car and great work !

Time for another report... a couple of races done again. First there was BRC at Tierp. After Ford Nats I barely touched the car; plan was to repeat what it did in Alastaro, but on a prepped track, hoping to improve et. Track was good, weather was excellent, event was really nice, but my car did not work. The clutch that had held fine decided not to hold at all, in any gear. Well, it held in the burnout, but slipped really bad in 1st, 2nd, 3rd... With my car it is too much work to do anything to the clutch at the track, so after three attempts I just parked it and enjoyed the event.
I think I saw this same movie last year, though back then it was the gas pedal :o

Back at home, and based on the advice from Niklas, Johan and Ron, I added weight to the clutch and shimmed it differently. Next events were SCC and FHRA Finals at Motopark (the other real drag strip in Finland). I chose Motopark. It was not an easy decision not to join SCC this year... I did the trip with a trailer 6 years in a row and it was always a blast. But it's a long trip, and the weather forecast was not good. So I was off to Motopark, this time with Pekka helping at the track. Another nice track, and nice weather.  Four passes Saturday and one Sunday. Finally the clutch was operating close to the way it was intended. Good news after the one-year-fight. Two of the passes were partly wasted because the clocks started before launch. Playing with launch rpm and boost we worked 60 ft down to 1.34sec, 1/8 mile to the 5s (5.96sec / 184km/h), and 1/4 to 9.35/231. Decent wheelie in 1st, too big wheelie in 2nd, and I ran against the llimiter for 0.3sec. My mistake - lost some time there, but not much. Back up pass was 9.42sec.

I have ran out of adjustment in the rear suspension, but there is something I should be able to do over the winter. Also, the engine is not making more power if I raise boost from 1.3bar - I have to figure this out cause the car could handle more ;)

Jyrki

Nice Jyrki! You are on track to plenty of 8sec passes.

Great looking car,it is a shame i haven't seen it at SCC.

Henk!!!

Last report for this year:

After Motopark I found a clamp in the pipe from IC to throttle body leaking, and replaced it with some 3" silicone hose. Hoping it would make more power I made the trip to Pistonhead Finals at Kjula with my friend Jukka. We arrived Friday afternoon, took the car to tech inspection and got everything ready for Saturday. The Västerås guys arrived in the morning with some ice for the liquid IC.

The first pass felt easy and nice. No drama from start to finish. The engine bogged down to 3400rpm at launch but still pulled 1.37 sec 60ft time. It ran 5.82/192.9 in the 1/8 mile and 9.09/239.8 in the 1/4. In the 2nd and 3rd passes the clutch started to get more and more agressive, and just spun the tires bad. 2nd pass 60ft was 1.52 and ran 6.00/193 in 1/8 and 9.27/240.4 in the 1/4. 3rd pass it was spinning like it was 2013 again  >:( 1.74 60ft, yes that is correct  :o Ran 9.71/229 putting it in neutral before finish line.

The car behaves real nice at 240+ km/h (GPS showed peak 244) without any aero stuff  :) Maybe it it is good to weight 940kg?

I am very happy I made the trip to Kjula. Extremely nice event, nice people, friends, lots of nice cars from nostalgia blown methanol to 4wd turbos and a nice strip.

I am also quite happy with the 9.09 and exceeding 240km/h. Of course it is not running as it shoud yet, but I have heard that it is not supposed to be easy  ;D
The ToDo-list for the off-season is done...

Thanks Jukka, Johan, Fredde for the help at the track.

See you in 2015,
Jyrki

Love your car and your reporting just as much!  Have a good winter and even better spring/race season 2015!

great report!

This has been a great thread to read. Very cool car

Been a while... maybe I didn’t write any reports untill now because the season was not easy.. Car was ready in the spring, and I took it for a test’n’tune in mid-May. With Tomi we drove 300km to Motopark; left very early in the morning and on the way it was close to zero Celcius. In Motopark it actually hailed, but in the afternoon the track was all good and we ran a pass. Clutch did not hold. Tried again with a different launch rpm & boost – no help  :(

Next stop Pistonhead at Kjula Dragway, travelling this time with Kari. A really nice event, and it was good to see Stian, Johan & rest of Västerås gang. My new clutch & setup only held for a second pulling a wheelie and then let go  :'( The hamburgers were excellent though  ;D

Then, with a new clutch setup, it was time to go to BRC Tierp. Our convoy consisted of Make’s cool turbo Superbeetle, Tomi’s uber-cool 240Z and my purpose built street car. Nice event, friends, Leif’s car making some serious passes, weather, and again really good hamburgers! I ran 3-4 passes, bogging on the line and finally breaking my Mendeola  :-[ Best pass was 9.5/238 @1.3bar boost, bogging to 1700rpm which hurt the 60ft

Even though I felt tired I took the engine & transmission out right after the trip and took the Mendy to Alhoracing, who had promised to fix it. He worked quite a few nightshifts, and made it all good again. All I did was to raise boost to ~1.55bar, and put the car back together.

Before the FHRA Finals we tested that it works as it should at the familiar truck terminal, and then I registered to the race. Weather forecast was not accurate, and the rain that was supposed to be over by Friday morning lasted till afternoon. Then it was time… first pass was not successful (spun the tires, 1.40 60ft, then slipping) but looking at the data we though we knew what had gone wrong. Next pass with less rpm and less boost it bogged to 1300rpm, killed boost down to 0.6bar, then picking up again and pulling thru gears. Car went straight and pulled a 9.07 and 250 km/h. WOW  :o with Stian’s old GT4294 it responded to higher boost  ::) Next day first pass with more boost at launch it pulled 1.39 60ft, 9.011 and 251km/h. Close  ???
I took some fuel out (it was rich) and on the fourth pass with even more boost at launch it pulled a wheelie, ran clean and effectively up to 1000ft, then misfired a little, I lifted and pulled the chute right after 1150ft. 1.35 60ft, 5.68 / >200km/h 1/8 mile, and 8.887 / 222 ¼ mile. 330ft, 660ft and 1000ft were really good. Pulling the chute early hurt the et by maybe 0.04sec, so it really doesn’t matter now.

Mission accomplished:
8
>200 half way
>250 full pass

Thanks to everyone involved, specially Tomi & Kari!

Cheers
Darren

Congratulations Jyrki!! Finaly!!  8)

Really loved the write-up. Thanks for that!

Oh, wicked ET for a street car too!

Wicked build. My favourite street/race car by far.

Glad you got on 8 ..

Onneks olkoon,Jyrki... :D ;D

Well done on the 8  8)  Now you can turn it up?  ;D   I nominate Niklas for boost setting duty!!!   :D

Or Skinne  :D  :D

Awesome, fantastic car

Congratulations !!!! excellent effort

Damn! Could not happen fast enough ;D

I can't wait driving a 11sec in a street car. Then a 10sec.. But 8? That is never happening..  ::)

A couple of weeks ago I took the car to a test'n'tune in Alastaro. First 0.12sec after the launch was good, then it lost traction, I shifted to 2nd gear which broke immediately. Ooops.

Yesterday I received some pictures from 2015  8)

Awesome Bug

impressive car , good numbers

^^^^^Those pictures are awesome! This is an incredible car! 8) Congratulations and fantastic design and work on your car. What a machine! Loved reading the thread more than once about how you developed this car.

I guess it is time to continue the tradition and write the annual report  ;D

After killing the Mendeola in May, I did not rush to make it to the next races in June. Not many races in July, so we aimed to make it to BRC Tierp. Kari fixed the transmission with a new mainshaft, and we tested that everything works driving around an industrial area – left some black marks there  8)

Bug Run Classic at Tierp was a really nice event. Track was good, weather was good and you could make as many passes as you wanted to. Same old story for me… I had to figure out what the clutch was doing (something totally new). After some tests it started to work consistently, and we did some decent passes with low boost. Then on the 6th pass the clutch locked 0.3sec into the run and the car made a huge wheelie. It still ran 9.13sec @247. After the pass I was afraid that coming down from the huge wheelie could have damaged to front shocks or wheelie bar mounts, so I just parked the car. Thanks to Tomi and my younger son for the help (he is 7)!

We also had an issue with the trailer – the frame was broken. THANKS TO FREDDE & JOHAN for fabricating and delivering custom parts to fix it so we could make it back home safe!!!!!!!!

At home I checked the car – all good except for the front apron that was damaged bad. So I made the decision to make the trip to SCC Gardermoen. Travelling with Jukka, we took the Åbo-Stockholm ferry that arrived 6:10 Friday morning… so we were at Gardermoen in late afternoon. The SCC crew had arranged perfect depot area next to Espen, so we were able to (once again) combine our infrastructure.  Excellent chili con carne Friday evening.

It was so good to see all the Norwegian good friends, not to mention our good British friends.

The new track was a positive experience. It rained both nights, and the weather was really good during the days. In the previous years the water would have risen to the track from the ground, but not anymore - track was safe. Also the shutdown area was really good; on one pass the chute dropped under wheelie bars, but there was plenty of room to stop the car (speed was over 250km/h).

Car was spinning the tires in 1st and 2nd, and I was using the width of the track ;) but it still felt it was under control, so during Saturday I worked the et down to 9.03sec. For Sunday we decided to try new launch tactics. It worked, but we ran out of time to make all the tests. Racing was open to 17:00,and my last pass was 17:00.22 ;)

Back home I checked the car, made some adjustments and test fired the engine. It dropped little oil under bellhousing. Flywheel seal  >:( I am glad it happened after SCC, not at SCC… btw it was the original seal from the 90s  ::)

I had a day off so I took the engine out and apart. Looked good, except for the seal. Afterwards I learnt that there would be one more race at Kjula… had I not taken it apart I could have swapped the seal and make one more attempt.

Well, even though I did not achieve any new records this season, I still feel it was good. BRC and SCC, several very low 9s, and the rush of pulling the chute at over 250km/h.

Goals for 2017: consistent passes, quicker et’s, what else?

Thanks.Well the (original) targets for the car were achieved last year  :P
so now it is just pure fun  ;D
Jyrki

Thats usually when the ET starts to improve  :)

THAT is so true, but such a long road to get to.

Jyrki, very impressive and great to read up on what it takes to make it happen.
