03GT_Hybrid · April 10th, 2008, 09:09 PM

280? i think I have a little more rwhp than that...?

B0B · April 10th, 2008, 09:13 PM

yeah a full bolt on 4v should be around 300.. you can safely push 400 to the wheels with a good tune and it will be reliable.

03GT_Hybrid · April 10th, 2008, 09:38 PM

yea seems like too much of a risk for me. Thanks guys

you can always get a forged rotating assembly first just to be safe, then throw some boost at it.
