Ive got a 2008 a6 vette with bolt ons and a tune. The guy had a whipple supercharger, cams, full exhaust, and runing 14psi. We raced from a 20 punch and I got the jump but until about 90 and then he passed me. Beating me by 1.25 car lengths by 120. He went passed me pretty good at 90 but wasnt pulling to hard aftwards. What type of power are these gt500 putting down wtih those mods? It seems like he should have demolished me but the guy also sayed he demolished the tires through 2nd. I was on street tires and he was on radials. It was a good raced, guess its true what they say, anthing can happen on the streets! His car was pretty slick
