The Cal-look Lounge

Hi Guys,

As the most from you know I'm trying to do a 9 sec. run with a NA engine, this weekend we achieved a 10.385 @ SCC, does anybody know if this is already been done in the past and with witch cars and engine.
If you know my car and have some ideas that can help me, I'll be glad to hear it.


Thx.
Sven.

almost all prostock cars in us run 9 with n/a engines, roger crawford rund 9 in his superstreet ghia.

dont know if any in europe runs 9 with an n/a you, jussi, and kemp is on the way..

The only one I know that has a license plate and has been driven on the street was Mark Reilleys (Ex Dean Lowrys Pro Stock) with a ARPM 3 liter engine.
I know JPM was very close a lot of years ago with his pro stock (sold to Norway I think). He made a 10.02 or so as best and I think that is the fastest ever in Sweden.

Good luck - aiming for the sky is the way to go!

I still have my race car, one day I'll start to chase you. :)

Bus engines do not count  :D :D

Sven , what is the weight of your car ?

Udo

My Unlimited Street car ran 10.30 @ 133mph, street driven 2276cc. It made 180 hp on moter and 340 hp on nitrous on Heads Up dyno.

Hi Udo,

Sven's car is 640Kg now,he went on a diet this winter as he is also doing some cycle-racing  ;) So i would guess he's around 710Kg all in...
Maybe Sven will confirm this...

Regards Steve.

If nitrous counts, then Bernard Newbury in Stitch Up is close - 10.001 @ 134mph I believe. Big Jaycee motor with a small-ish squirt of gas.

Nitrous is supercharging and Svens car does not use nitrous.

GO GO GO Sven!

Dave Dinning has run a 10.39 @ 129mph,

He is aiming for a NA 9 sec pass too!

The race is ON!

- Sven
- Kemp
- Jussi
- Dave

Who else?

maybe andreas åberg in the "herbie" i think his done 7.1 in the 201m so far with his "small engine" and theres alot of potential there. And wht about thomas kemp?

Marcus, Andreas Åberg have pro stock Chassi from Chassishop,
Sven,Thomas,Jussi and Dave have floorpan car ;)

Magne

That's it . If you put a Ron Lummus chrom molly chassis under Svens car he will go 9's ....
640 kg is too heavy

Udo

sorry i just thought it was a nine second na car in europe that was the topic. ::)

I think it is possible anyway. Just add more power!

The super Street cars has smaller engines and about the same weight.
Super street regulations: 10.75 lbs per cui, minimum 1500 lbs including driver.

2789 cc= 170 cui, 710 kilos is 1565 lbs -> 9.2 lbs per cui.
If a super streeet can do a 9...

Hi guys,

Total weight include myself is 710kg and this will  not change because i will not put any polyester or carbon parts on my car and the floorpan also stay.
I guess the only solution is find some extra pony's

What about bigger carburaters, currently i have 58 bergs but we have max. power with only 185 mainjets, maybe when we can more air into the engine we can use bigger main jets ....?
I do have to mention that we totaly have forgotten the venturis in the carbuarters they are only 48mm and the inlet valve's are 50.5mm, maybe I can start to make the   venturis bigger.

The jet size is depending on the vacuum signal from the engine.
It does not have much to do with the power.

I had 48 mm vents in my 58 mm Terminators with the same intake valve, but I never experimented with anything else.
I would go for a dyno session and experiment with different lengths on the intake and the exhaust and also vent size as you mention.

May the force be with you!

i wish you good luck on your quest sven.  UD  .

My pro stock runs in the 9's with a 2442 engine NA 8)

A way to get more pony's is to reduce spring pressure... in other words get a Raptor cam from JPM.

do you get free sticker from JPM?  :P

nah it makes sense what you say.

GO, GO, GO Sven.  don't forget it is a 'heavy latemodel' as well  ;D

My car improved from 12,65 to 12,17 from a change to JPM´s cam. And there is more in the car with a 1,7 60 foot. Before the 12,65 last year I had a proper dyno sessong, but not now.
Sven, call Johannes, I´m sure there is more HP to be found!

And NO, I don´t get a free JPM sticker either!!!  :D

My early 59 is 75 kilos heavier... It made a 10 with a flat cam and street tires!

Dude, that is exactlly what he was saying: with a flat cam you need less spring....Its so simple, yeeezz!  ;D

Sven,

According to my calculations you will need 310 rear wheel HP to manage a 9.998 sec run - 132 mph when you car weigh in at 710kg - 1565 lbs.

Best rgs
BB

Edit: I realize that my calculations are wrong. Your car is lighter than the weight I used. Good for you.

290 hp at the rear wheels should push you over the line in 9.920 secs.   

That means someting like 320 in the engine. With 2789 cc you need 114 hp/liter. Not easy, but is possible.

I know ;) At the moment we have a bit more than 102hp/l. After Das Drag Day I will change some things and we'll try and hunt for that 9 second pass! :o

Cheers,

Christoph
PROFORMANCE

Hi Dominick

I have seen in Hot VW's from 2000 that Perkins did a super street record of 10,14 !! I think it was Dave and may be you know what car it was ? Nearly the same times that Roger does now in the same class

Udo

That is the car now owned by Jack @ Jay Cee Ent. and driven by his son Zack, and the Dave Perkins is not the same person that helps me, there is two of them.

Ok thanks . 10,14 was very fast at that time ...

Udo

Do the Berg 58's have profiled butterflies and throttle shafts?

No they don't. This is extra labor at BERG's,don't know exactly what they charge but the 58BERG's are sold without this modification as a standard on the shelf item.

Regards Steve

Thanks RUN IT and congrats with the 9,9 run!

It is with the Bugpack Super Stock engine? pan car? Nitrous?

BB
Norway

I believe they still have the tooling for the butterfly's, not sure about the shafts. That fixture might have went after when Andy had passed away.  But they did work. Worth the extra money. When I worked there Andy did a set of both butterflys and shafts, and they did help. Still have the set and there put away, for another set of IDA's.

Ted

Thanks BB,
That was with my 2470cc Super Street engine running Berg 58's all motor. Its a pan car we built in my buddies back yard! We ran the Super Stock engine this weekend and ran a 10.85 @ 126+ at 12lbs per ci. We dropped it down to 11lbs per ci and never got a full run but even with problems it ran a best of 10.66 @ 130.30 with stock replacement head castings using 44x37.5 valves. Right now I don't know which is more impressive, the Super Street motor is state of the art and the Super Stock is completely off the shelf!!

Hi

that super street engine is very nice. Must be like Rogers engine !? I hope i can see them racing at Fontana next month  :)
I think you do the head work at heads up performance ?

Udo

That video give me goose bumps.
Great to see it again, and good work Doug and Anthony!!

Would be very happy with your timecard Sven .. Very impressive indeed . Congrats again .

Erich 

Thx.

I hope I can improve it at Bitburg, we are adjusting and testing the suspension and clutch for Bitburg, a lot less grip overthere but still a fast track, you never know!

Sven.

Sven, it would be awesome to see you over here racing next year :) The best races for track prep are FIA rounds at Santa Pod, 1 in May - 'The Main Event' and then in September for the 'European Finals' (this is on now at Santa Pod') Last year at Euro Finals we had 13 passes over the weekend!

It was great to finally meet you at SCC  :)

Pat Downs from CB Performance was running consistent 9.50s and 9.60s at 143 mph this past weekend at Sacramento with a his 2800cc N/A engine competing is Pro Mod.

I want to do this with my floorpan and full metal body, no tube chassis and no plastic.

Thats is the right way to do it :-)

Is the goal only for race or streetcars? I would like to make a new goal for those streetdriveable cars for next season, first we fill the fueltanks in normal gasstation max 99 octans std, then drive that 30 miles etc drive on the street to the raceplace, there put wheeliebars + change maybe stinger on + get belt off if needed, and then we will see what times comes up...
We are not using 85e because from my carage it is 65km to the gasstation where to get it and also on rally + circuitrace it is not allowed here.
Next week i am putting my old street engine back on circuitracebeetle and if it works ok that one more 15 lap hard circuitrace, then i will take it to JPM dynoday for test ;)

Jussi

Cool idea, but no fan belt off I would say, as that would not really qualify as street-ready to operate. I understand the wheelie bars if you think you need them from a safety point of view  ;)
The stinger...mwa, if you think that really helps you a lot  ::)
Street cars are so much more fun I think.

Yeah.street legal.

Dirk

Here is one of my 9.60 runs at 143mph

Hi Pat

Sounds very smooth and not too much rpm's !?  :)

Good luck Udo

Thanks Udo, I was shifting the car in every gear at 9300 and going through the lites at 9200. I think it was were the camara was mounted that made it sound like it wasn't reving high.

That was SOOOO cool Pat! Great vid but thats due to a great n/a engine!
Man, that revs quick. :o

Nice drive!!! 

And for the streetrecord: ok, belt on + mufler on, just add the wheeliebars if needed...
 

 ;)

HI Pat,
Well the very first time I red your mph I was really impressed as you reach turbo engine car  speed!! ::)
really awesome car/work ! 
it's hard to keep the way in the N/A engine due to the hard work we have to go really fast ...  comparing to the turbo set up
But it's our addiction too !!   ;D ;D ;D
cheer
JR

Thanks JR, I plan on getting the car to go faster soon. Been playing with some different gear combinations. Mike and Sam at Rancho are helping me with a new gearbox, thanks Rancho! Went to a taller gear set and lost a tenth in the eigth mile but got it back in the qaurter mile. Need to go back to the original first gear and I think I have a 9:40 car.

Just out of interest does any one know what other makes of car running 4 cylinder naturally aspirated engines run 9's or are close to running 9's, or perhaps even faster. I can't help thinking the Jap crowd must have some quick cars, but as with VW's the turbo cars are the ones grabbing the headlines from what I can see.

Hats off to you guys who are trying to make it into the 9's, 2011 should be good to watch!

Peter

I think some of the Japanese makes have run very low nines.(FWD!)
They may have even cracked into the 8 second zone by now,
but we we probably would have heard about it...or perhaps not!

But they all seem to be running with hairdryers. I've spent a few evenings browsing all sorts of drag stuff on the net, and it seems that most 4-cylinder N/A cars are struggling to make it out of the 12's! Wheen the going gets tough, most bolt on a turbo! :D

I believe Roger ran a 10.004 at Fontana earlier this year and was having transmissions problems and missed a shift on that run

So are you saying these are N/A times? I struggled to find anyting 9 second type quick (N/A 4 cylinder) outstide the VW world on the net the other night. Perhaps I just don't know where to look though? As ever the rotary boys are right up there though.

Peter

Do not fall in to trap to considering a rotary motor comparable to our little motors. By their nature rotary engines are able to perform both functions (intake & exhaust) on the same rotation thus effectively doubling their horsepower potential. Rotary engines should have their advertised displacement doubled. Proof of this is in their fuel consumption levels, much closer to that of the bigger V8's. Nevertheless due to superior head design you will definitely find newer NA 4 cylinder engined cars typically running quicker than our VW brothers. Wayne

Sorry about the Honda content! Always good to know what the enemy has in their armory.
Now back to the Volksies!!

fair play that is no nonsense quick, but I don't think the ACVW guys are doing to bad when you consider the starting point.
So the next obvious question is who has the fastest all motor ACVW car? Also are the ACVW's ahead of the WCVW's or not?
Peter

Found this:
http://www.eurosportscompact.co.uk/entries2010.php
Looked through and I think the quickest without a turbo is a Scirocco running 11.95! Everything else is turbo'd...
