Ive run as fast as 11.9 at 114 in this car with the e heads and roller setup and have driven lots of cars but its never had this top end. This is hard to call since I have done all the handling stuff like tubular upper and lower a arms, qa1 coilovers with 550# springs and 1" solid sway bar and poly ends, and reloated corvette shocks in the rear. Its a really tight ride and I know it would eat up a new ZL1 Camaro as I just drove one of those recently but I would equate it to a heads/cam C6 Z06. This engine revs quick! Its not uncommon to hit the recall on the tach and see 6300 rpm! But once the boost hits in second it just winds up so fast its almost a race to balance being pushed in the seat, checking for cars up ahead, and jumping off the throttle. Id have to say if I can hook, this car it should be good for low 11s. Id really like to turn it up to 12 lbs and leave it there. I also need to program in the rev limiter to 5800 rpm!

My original 74 GTO wieght around 3,400 with a 3.42 gear and a turbo 400 trans with a stock converter the engine was a 455 with a crane fireball cam the heads were stock and a stock. It had a small b & m 174 street charger, the car ran the best of 10.89, I never ran more then 9 lbs of boost!

Its about 4600 feet above sea level here and Tucson usually has an awful DA. Its one of the slowest tracks out there but when I get there ill be sure to post some numbers. And its got factory manifolds installed the same way as they came from the factory. I did all the piping from there up to the turbo and 3.5" downpipe to dual 3.5" exhaust. All the hot side was done after the manifolds in stainless steel and the cold side is all aluminum TIG welded together

Did you run the hot side from the manifolds to the front, under the control arms? Any clearance issues if you did?
