    how much CFM in intake?

    Can anyone inform me of how many cubic feet per minute oem intake and aftermarket intakes are capable of - short ram, cold air. Anyone know how many cfm's a turbo is capable at certain lbs of boost?

    the answer to this will be different for every type of turbo, and every type of engine.

    even for f22s, the exact cfm will vary.

      Yep what type of filter element, intake design, and such all play a big role. But whatever it flows better than stock thats all lol.

          yes, of course it is all depends on what type of filter and intake, and engine possibly. however, can anyone provide any found fact on any setup? just wondering. I guess all you would need is a some sensor to measure the wind speed in feet per minute inside the intake and then take the cross sectional area of the intake. Of course this would vary on if the car is running full throttle or idling or in between. and then you would have variables such as air path, turbulence, and meter accuracy.

            The only way to really say would be to flowbench it.
