Yeah, turbo definitely can't push 30psi efficiently at all........

thats an evo 9 turbo, 16G6, and at 30psi its is NOT efficient. if you think 65% is efficient your retarded. your also assuming its going to flow 580cfm (irrelevant) at a 2.0 PR. thats also retarded.
so what was your point again?

So you guys think that when these guys are pushing 850whp out of a GT42r at high pressure ratios, their compressor efficiency is 78%? I'll tell you in advanced, it's not. Hello, mid to low 60's! I used to think pressure efficiency was key. I was dead wrong. Flow is way more important. Intercoolers take care of compressor efficiency or lack there of. If the pressure and flow number land on the compressor map and aren't near the surge limit on either side, it's plenty efficient enough to go fast. Everything else is just nonsense. If you went by compressor maps, GT35r's are perfectly efficient on b18c1 engines at 10psi. But when you go out into the real world, they have lazy throttle response and spool 1000rpm too late. Magically when you throw a GT30r, the damn car makes more power just about everywhere, runs better times, and responds like a healthy car should meanwhile compressor efficiency is not as preferred as the GT35r. Flow is king.
