evo 10 = 9:1 compression and they are around 22-24psi stock
also the spool of a 30r chould hit full boost at 42-4300rpm
but on my turbo which is a 30r wheel shoved in a stock evo turbo housing will hit full spool at 3800rpm

Is the EvoX Direct Injection?
How the F do you get 22-24psi on a 9:1 motor with 91 or even 93 octane, even if you're intercooling like crazy? The timing must be down to nothing . . .
