Here is a stock ls1 on i think it was 10 psi meth on STS kit that we tuned awhile back. IT was also on 3 bar speed density.

I don't know much about them either but what I do know is that the size really only changes the max output and the speed/efficiency. Say you have a 76mm on a stock LS1, it may start building boost around 3500-4000rpms and max out probably not untill around 7500-8000 rpm's. Now say you have an 88mm turbo on the same engine. It will start making boost later like around 5000rpms but pull probably well past 8000rpms. If both turbo's are wastegated at 10lbs, the only difference would be how fast they can reach that 10lbs boost mark.

I think this is right, someone correct me if i'm wrong.

Just like comparing blowers and turbos same overall effect, just efficiency and how you spin each compressor.

I think I have some 70mm and some 88mm dynos on the site. PLus a few stock lsx with APS kits.

Was he running stock manifolds? So you guys could tune that shit for me? Do u think if I did H/C/I and just left the turbo not connected I could drive it to you and we could connect it and dyno tune that bitch?

I don;t remember what all mods he had, it was awhile back. I just remember it was a white T/A with an sts kit. But yeah just leave the boost pipe off the throttle body and drive it easy.
