    Mathematical formula

     



    For a street car the formula is (RPM X Displacement) / 3456 and multiply the result by 0.85 (85% of efficiency). If you dont care about fuel economy just put more efficiency like 95%. Normally 110% is for race cars only. With this formula it will give you the CFM of the carb you need.

    Good day
