We tried boost levels anywhere from 18-21 psi but anything over 18 psi provided minimal gains. Tried all the way 23-24 psi as well but the system was maxed and just ineffiecient and made no extra power over the lower boost levels. Next is to build a sheetmetal intake, install cam, and possible some mild head work and look for 450+whp.

Re: pretty quick hatch
umm i like pie, so cutting it i guess would make it easier to fit in my belly, so i'm down with pie cutting. anyway, I've seen lots of long tube, probably equal length turbo manifolds on higher horsepower cars lately, whats the deal with this-- how does a longer tube help with power? just curious about the science behind it. how is it different basically from a shorter length thats close to equal such as a ramhorn manifold versus the longer tube equal length headers?
