12sec 1776 challenge

[Speed-demon]

Remember that the headstuds probably need to be shortened too. Lots of work to build a narrow engine.... Looks good!!!!!

[Anders]

Thanks, shortened them last week. Had to take of material on both sides. Made sure they cleared the manifolds and rocker arms. 

[volkmaster]

Any news from JPM dynoday Anders?
 

[Trond Dahl]

205.4hp!
Great sounding engine!!

Hi guys,
I suppose this update is somewhat long overdue

After long days and nights leading up to SCC I was able to put the engine together and get the car somewhat ready for the strip. (Big thanks to everyone who helped me along the way)
Since the engine had been shortened 30mm the CSP torque bar now came in conflict with exhaust pipe #3, I had to cut it off and did not have the time to weld it back in.

I mounted a Bugpack traction bar to compensate for the loss of the torque bar, but about 3 meters after launch (and a lot of wheel hops later) the right axle broke... being the 1st run and all it was kinda lame!

Long story short: I replaced the axle went down to Johannes @Dynoday and made 205.4hp. I felt OK that day!

Next in line is to upgrade the rear with 26mm torsion bars and raising it a couple of notches, weld the CSP stuff back in and get the cooling tin sorted.... and of course buy a new gearbox that doesn't give me a top speed of 270km/t.

The 12's is definitely within reach.

BTW. The engine never maxed out, the curve was still pointing upwards when Johannes let of the gas.
The dyno was spinning at 250km/t which someone might say is less than ideal.

The sound in the engine at Dynoday was awesome!

Johan

[Black_65]

No that is very cool numbers .

Sorry to ask but what ignition are you using? i.e Dizzy etc

[JS]

The sound in the engine at Dynoday was awesome!

Johan

Very true, really something else for sure!

Thanks, that was a day to remember!

[GreenTom]

Good numbers. But you acheved about 186HP (139kW) and 204 Nm as I see. After sorting out the wheel hoop you should get 12s pass. Looking forward to see it in action.

Good luck.

[Anders]

Thanks Tom,
Those numbers were at the wheels. Unfortunately Johannes' printer gave up at the end of the day and we wasn't able to get the all the information out. 

[GreenTom]

At the wheels? so that is really good numbers. Could you ask if it wasn't calculated to flywheel power and torque (most rolling road do that)?
I think that the numbers are calculated to flywheel power - If it was typical wheel power you should get 3rd graph line with gearbox loss (I'm not sure how it's called in english).
Anyways, really good numbres, congratulations.

 

[Anders]

If you look at this link, http://bit.ly/1cjgGXC, you'll find the numbers from Eivind's car how was on the dyno after me. It has some more information regarding wheel and flywheel kw.
Don't know why I didn't take a picture of that view only with my numbers.

Oh well, I guess I just have to back up the numbers by producing decent times on the strip...

You took your picture too early Anders. He displayed the calculated flywheel HP afterwards.

That my friend will be the most difficult task now that you built the engine. The only way to get your car over the line fast with an engine like yours is to reduce weight and to build a custom gearbox with suitable ratios.


The easy approach would be to buy one of Russels lightweight gassers 

[Anders]

I see, should have waited a bit with the pictures i guess, maybe I'll go back once I have a proper gearbox to see if we can find those extra couple of horses.

Buying flakyjake shure would be easy, but where's the fun in that
One of my initial goals was to have a 12 sec street car powered by a 1776,
it will remain undefiled for the time being, at least until I build a new car.

[modnrod]

One of my initial goals was to have a 12 sec street car powered by a 1776,

Damn.
That's tough.
With your HP you should do it OK if your startline weight is under 900kg you would think though.
Are you going to make it even tougher on yourself and use radials?  

[Anders]

Certainly tough on the wallet. 
I'll put on some proper slicks when I'm racing, bought some phoenix slicks at SCC from Richie.
Plan is to buy separate rims for race/street, so once I get some passes in I can try the street wheels for fun

[Peter Shattock]

Great stuff Anders! Well the power bit anyway, sorry to see you broke the gearbox before you got a good run in.

It certainly looks like you are well and truly on the road to financial ruin now!

Welcome to the club!

Hope you you can get the car back in one piece for next year and have some fun!

Peter

[Anders]

Thanks Peter,
I should be able to put together a box during the winter hibernation, lots to do at work so I can always put in some extra hours if the wallet bleeds to much.

Ending the season on a high note after Dyno day certainly helped my motivation!
Garage night tomorrow and I'll start by putting together a todo list for next season.

[Anders]

Had a couple of hours in the garage today and continued the job on fabricating the cooling tin.
Will send them of to powder coating once done.

Did a leak test earlier this week with the help of Kalle (Thanks).
On a cold engine I had 2% leak (rings) on cylinder 1,3 and 4. number 2 had 4% with a small leak from the exhaust valve in addition to the rings.
Expect the leak to be close to 0% once it warms up.

[Anders]

More fiddling with the cooling tin today.
Starting to get somewhere, maybe I'll have it done by Christmas.

Received this little thing in the mail the other day, intended for my next engine project.

[ Attachment: You are not allowed to view attachments ]

[Anders]

Not much done this week, but I had a talk with JHU and came to the conclusion that my current solution to the shortened cylinder tin  and fan housing problem, might cause added turbulence and less effective cooling of the heads.
Took a step back and cut away the extra I welded to the cylinder tin and focused on shortening the fan house. Got the width I wanted so now I have to create a smooth arc to make the housing look like stock.

[Anders]

Still not a lot to report as far as cooling tin goes, but received more parts for the 1600.
I'm going to use a holley 2100 setup which I got on thesamba, looks to be in decent shape.
Got the Stack and filter from socal speed shop, personally I think it looks a bit flashy. Will have to do something about that one day.

[ Attachment: You are not allowed to view attachments ] [ Attachment: You are not allowed to view attachments ]

Has anyone any experience with the dome filter btw, read somewhere that they were a bit flow restricting but can't seem to find it again...

Anyhow got an old scruffy exhaust to go with the engine as well, not usually big on chrome mufflers but might let this one pass. 

[ Attachment: You are not allowed to view attachments ]

Suppose I have to start another thread for the 1600 soon, so I don't clutter up this one..

[modnrod]

Those mesh filters look and sound cool, and at least they don't melt and drop chunks of foam into the carb like a Ram-Flo I guess  , but they are restrictive.

Generally they reduce the available area into the carb by 30-40-50%, depending on mesh weave.
Oops! Now you have a ONE barrel Holley 2100!

Sliding one of those up into a stock oil bath assembly (after removing the mesh) is an option. Dual inlets to the air filter body, 6" x 4" filter inside it (450cfm flow)...........

[Anders]

Thanks man,
Appreciate the input! The mesh filter is easy to take off/put on so I'll be able test it out once I get the engine on the dyno.
A 'one' barrel 2100 is not quite what I had in mind

[Anders]

A little more done on the cooling today.
Got a hold of a new set of cylinder tins. Made them fit the narrower engine and shortened the fan house as well.
Hope this will result in decent cooling. Next is welding them all up and getting 'em ready for paint.

Hi guys,
Hope everyone enjoyed Easter and got lots done to their cars; getting them fit for fight for the coming season.

Not a lot of progress to report from my side, since I'm the the process of moving and has acquired me one of these:

[ Attachment: You are not allowed to view attachments ]

But thankfully Jussi and Kuplapaja has been hard at work in Finland making me a nice box to go with the engine.
I'm excited to try out the dogrings and the finish gears to see what times can be made with this combo.
The ratios are:

3.70
2.31
1.68
1.39
 
3.88 R/P

Making it a really nice freeway flyer, or not

Erlend and I treated our cars to a day at JPM's Spa and Resort on July 10th.
After a nice 500 or so kilometer cruise down to lovely Helsingborg on Thursday, with a short stop to pick up Johnny, everything was set for a day of wrenching and coffee drinking on Friday.

Main problem needing attention was poor drivability, with too rich idle and leaning way out on gentle acceleration. After a quick session on the dyno to recreate the problem, the decision was made to add the 3rd progression hole to the old Italians. A quick hour with wrencing and drilling later; the carbs where bolted back on to the motor. The result was instant and the previous flat-spots where all gone, great success! The later test drive really left me baffled on to how good such a, on paper, aggressive little mouse motor can behave in traffic. Truly smooth as silk... well almost
  
After some more wrenching, tuning and coffee drinking we ended up with 198hp @ 7630 rpm, not bad for a 1776cc, but a couple of horses less than the previous numbers from Dynoday 2013 (205.4hp @ 7900).

Anyhow the 12's are definitely within reach this season and with SCC coming up, I'm really looking forward to see what it can preform on the track in a couple of weeks!

Thanks for the help and a splendid trip Erlend & Johnny, I had a blast!
