green lines would be the power it takes to drive the supercharger... wow!! 20kw at peak efficiency!!! that kinda... sucks 
pressure ratio is (boost + atmospheric)/atmospheric.
so if you were running 14.7psi=1bar=1atm boost, your pressure ratio is 2.
draw a horizontal line across at 2, and then you get the efficiency at different air flow (in cubic metres/min, which is similar to CFM, and you work it out by the speed of your engine x the ratio of the SC drive pulley x the volume the SC pushes per rev?? )
