How much would a 1997 LS1 A4 Vette make with the following mods:

MTI Stage 2E 205cc heads
226/226 comp cam
Fast intake
90mm T/B
ASP pullies
CAI
Borla Exaust
Long tube headers
No cats

 

My friend has a 97 LS1 Vette with similar mods.

Vararam
Ported LS6 Intake and throttle body
Cartek 2x Cam and HEad package
Kooks LT's
B&B 3 inch
3.42 hardened
Hardened Output Shaft

395rwhp- He runs even with his Dads 2002 Vette Convertible somehow, both are A4's

I'd say 405-430 rwhp, considering that I don't know how good those heads are and it depends on if the torque converter is locked or not. When you lock it, you can gain around 4-5% on your dyno.

 

Heads/cam/FAST intake, it seems that most guys get anywhere between 420-485rwhp. I'd expect ~450 if the heads are decent.
