How do you know the max PSI a turbo can run before it maxes out. I know compressor maps give a good Idea. However what is the max psi the following turbos should be run at just from experience. Example you wouldnt want to run 30psi on a t04e 57trim turbo. Also I realizing that the intercooler will help but at what point will it be out its range. I also realize the exhaust a/r helps to but I just want examples for a reference point. Thanks in advance.
