Re: Turbo PSI vs. Boost

Well no, you need the compressor map and what kind of PSI your looking for.

The air is measured in lbs/min at a certain pressure ratio. That is the outlet pressure/inlet pressure. Then you want the turbo to stay above 65% efficent and under the max RPM limits.

I found a nice little free program that caluates most of this for you, then with a compressor map of the turbo in question you can check it.
