Again... anything?

Thanks Brian.
So 15PSI at 18k blower speed looks like it should be about 1500CFM.
Do you know what inlet this is assuming? Obviously as we have seen there is a drastic effect in changing from say a 90mm throttle body to a 102mm inlet. In that instance the blower would make more boost, and the slightly left pointing green RPM lines would not be accurate as CFM increases while boost increases for a given RPM.
Do you have anything on drive loss based on boost and RPM?

Rob,
You are really asking for volumetric efficiency, although im not sure if you know that.
By drive loss, you mean power required?
That one is easy...(boost*SC_CFM/229)/Adiabatic_Efficiency

I do know that, but I'm trying to put it in simple terms.
What I dont know is how to calculate how the different inlet changes the game lol. I was hoping someone could do that for me. And rather than take that chart for its face value, i'd like to know what values were used to calculate it all.
And by drive loss that's exactly what I meant. Thanks.
