Like in the following: Compressor maps - examples and explanation |
You're missing the fact that you are confusing flow rate and PSI and what each means to the motor. CFM coming out of the compressor has nothing to do with the PSI (the amount of air) entering the motor. The motor can only naturally accept (Naturally Aspirated) so much air. Forced Induction does what it says forces more air into the motor using a generated pressure difference (PSI, bar, etc.) CFM only comes into play if the compressor cannot flow high enough to make the desired PSI.
