well the formula is available but i don't know many cubic inches my 95 integra gsr motor has...i want to get a big turbo for my car but i dont want to get one that is too big and not be able to make power until 8000 rpm or whatever. if anyone can help me put this formula to use that would be great. thanks


Engine Airflow Requirements

In order to select a turbocharger, you must know how much air it must flow to reach your goal. You first need to figure the cubic feet per minute of air flowing through the engine at maximum rpm. The the formula to to this for a 4 stroke engine is:

(CID × RPM) ÷3456 = CFM
