pressure drop goes up with the square of the volumetric flow rate, or more specificly the square of the velocity of the moving fluid.
FYI, CFM through into the turbo is not the same as CFM out of the turbo
But if you keep it all as mass flow rate, and not volume flow rate, you don't have to account for it untill you want to find system pressure drop!!!
