Guess my dyno numbers
I'm going to be putting my vette on the dyno in a few weeks. Anyone care do guess my RWHP?
Here's what I have:
'04 A4 Coupe
Engine
1) Dart Pro 1 205cc Heads (10.9:1 compression)
2) 228/232 .571/.578 112LSA cam
3) Fast intake
4) LS2 TB
5) BBK shorty headers
6) Yella Terra rockers
7) P1SC with 4.25" pulley (around 5-6PSI)
Trans/diff
1) Yank SS3600
2) Z06 3.42 rear
Exhaust
1) Z06 titanium
That's the main stuff anyway. What do you think I'll put down?

Here's where the higher gear ratio and stall have another positive effect. They make life easier on the drive train. I do think it would be wise to invest in a solid trans mount to avoid wheel hop, and a trans to diff brace for strength with that kind of power. But I think it will hold up fine. I am on a similar track with my mods as you are and plan to run the stock A4.

So I never brought the car to the dyno, I just decided to tune it myself. Its a bit of a learning curve and I'm a long way from being an expert but I enjoy tuning the car as much as I enjoy working on it so why let someone else have all the fun?
I'm running 345/35/18s w/A4 and car won't hook at all at in 1st, so I don't even try (they aren't drag radials so I don't expect much bite). If I lay into it slowly in second (which takes me past 70mph) I can get traction, but on a cool day it will break loose pretty easy as well. I haven't spent much time in 3rd other than to verify AFR (11-11.2) under load.
Max boost in somewhere between 5-6psi with the 4.25" pulley. Id like to pulley down but I really am pushing my luck with that stock tranny the way it is. Plus tuning on the street sucks.
I suspect with drag radials and a strong tranny it should run high 10s. Enough for now (not really). Next stop:
1) RPM transmission
2) Max boost the P1SC (9-10psi?)
3) Meth injection
700 whp anybody?
