i still completely disagree with you on that. The biggest measure of where CFM's will count is right at the valves, where the air enters the engine. 10 PSI pushing on them is 10 PSI whether it comes from a star turbo or hrc turbo. IF you think back to days of chemistry class, the amount of air present in that container (intake manifold) is all related to the pressure(boost), volume of the container(intake manifold), and temperature of the air, which with two quality intercoolers, should not be much different. No where in there does it come into play with CFM's let alone CFM's being a measurement done at the outlet of the turbo, 9 miles of intercooler piping away from the intake manifold and valves which controll the amount of air that enters the engine. Look at what sensors controll your engine, a MAP sensor, and intake Air temperature sensor. It uses these two values to increase fuel or decrease fuel for that certain rpm.

The way i see it, if you had a star turbo with hahn fuel system, it will run exactly the same!

But alas, no one on this board cares.
