Well I guess I should jump in seeing as I personally have raced a 2006 ZO6 with a procharger pushing 8psi, in my old GN. From a dig the Z was useless and from a roll it was very impressive but the ol GN stayed glued to his drivers door all the way up to 170 mph and thats when the GN started "Floating" all over the place, sucking the windows out..

"Scared the living S**t out of me!" We then went from a 30-35 mph roll, I jumped a half car on him and kept it! The owner of the Z is a good friend of mine and he said to me he could not belive how I stuck with him.. This was done on a old airport runway for a photoshoot...
My old GN was built pretty good however but never had it on a dyno so I will never know what it had for RWHP. I drove it all the time on the street, Autocrossed it and we even drove it to BG for 3 yrs and back with my son. We drove it all the time and I have to say, On the street it was plain scary! BTW I was running 23lbs of boost, 93 octane with Dual nozle Alky Control's set up...
