I think so, I am doing the math at all RPM's at all the pulley sizes. It may take some time.
Compressor Max Pressure
On the map, find the top-most point on the graph. The vertical coordinate is the max pressure ratio. For example, 2.8 pressure ratio at sea level is 1.8 times the atmospheric pressure, 1.8x14.7psi=26.46 psi.
Compressor max pressure is limited by compressor wheel speed. It's physically impossible to boost higher than this max pressure for one particular turbo. Plus the pressure drop in the intercooler system, the actual max boost reading from a boost gauge that's plugged into the intake manifolds maybe a few psi lower than this max pressure.
Yes,
PR of 2.0=14.7 PSI of boost that is at the compressor outlet and very hot. You loose some of that as pressure drop across the intercooler.
More as the volume shrinks when the are is cooled by the intercooler.
