Wheels up on a circuit car is pretty damn impressive for sure! I would definitely be worried about something breaking but it's good to see everything held together.

Since I got my car dynoed I've been looking at your dyno sheets more. Is your car 381hp/337trq at the wheels or is that corrected flywheel horsepower? I'm going to be adding a water/air intercooler on my setup so I'm wondering how much power I'll pick up. Also what intake temps are you hitting when you're up around 15-20 psi?

I was actually a worried, as my buddies car did break his transmission and it would have been my only possibility to piggy back to the mainland as his car is (well, was :D ) a street legal car as well and was towed on an ambulance to the event. The wheelie was after his car already had broken... but I went for it anyway :rolleyes:

Yes, that was corrected flywheel hp ;) Coorection for whp is/was about 15%.
IAT not sure exactly, but those are usually pretty low, around 25-30 Celcius ( ~70-80F?).

At Santa Pod I was running a 'little' more boost and a little more timing, so I think I'll revisit the dyno again sometime to see what that was ;)

Nice work. Love the "wheels up" shot.

having seen wallys car last weekend, i can say its an awesome car every run seamed easy, no fuss, no effort a very well put together car with a nice guy driving it :)

cheers andy

Thanks for that Andy! It was definately great finally meeting up with you guys. The photoshoot with all of us on the track at once was real fun too!
Definately hope your car is there next time. It sure sounds very promising what you've build so far.

The clutch I run now is not as effortlessly to operate with drag starts mind you. The wheelie was actually a real big bog, but the other way around, but don't tell anybody I said that :rolleyes:

and welcome to the german car board ;)

Wally,

This really beautiful picture! :eek:
One question ... the clutch is noisy or works smoothly? What are you thinking now about the double kennedy clutch?
Thank you.

That are two questions :)
Actually both: its noisy when depressing the pedal, but smooth on all other moments.
So far, only this kennedy double clutch holds the power and gives me a light (=street friendly in my book) pedal.

More surprising is the stock cast flywheel still holds. I would rather have a steel ('forged') flywheel, but only 200mm and 215 seems to be available (the 215 only very recently and is not in stock afaik).

Received this photo from Santa Pod's official track-side photographer. I really like this one.

Very nice pic!! :rockon:

Wally September 21st 2010 10:29

Tnx guys!

I seem to have reached some sort of goal already with the latest dyno run. A goal I had planned only after some major engine updates for the next year(s), but this one already took me there :)

This is corrected engine hp at the crank. Power at the wheels was 342.4 at 6150 rpm. BTW 500 Nm ~ 370 lbs.ft (also at the crank)

The remaining goal is a '10 second' car...As I am only an '11-second driver', that goal may take some more time and/or even more power... :lmao:

Humble September 21st 2010 11:42

Damn, those are some good numbers. What turbo are you using now? I'd like to clear 300whp with the addition of an intercooler.
