I'm on a blown turbo running 10psi (bad thrust bearing), but last night I was messing with a new CL with gauges, exhaust, etc.. And we took off from a dig at a light, and he was no less then 1/2 car back til 80mph. I know at 10psi I'm probably only doing 350whp, but dang man... I was supprised, I almost got embarrased by a Honda and even tho I was at 10psi on a blown turbo, I would have never heard the end of it.
