with my small 16g i'm hitting 20psi by about 3700rpm but even running 22-23psi i doubt i'd break 300 whp on a dyno (did it on a virtual dyno but we all know how accurate those are) big thing is the fall off at high rpm, although not near as bad as the td-04 its obvious...
you still have pretty much 300whp by redline!!!
seems like an awesome turbo and if it is indeed an 8cm thats really good spool on a 2.0L
i was considering a 16gxt but i'll wait and see where this goes
