Air Flow and Fuel Flow Calculation
Speed-Wiz can calculate air flow and fuel flow based on the engine specifications you enter. Fuel flow calculated based on the proper mixture ratio for the type of fuel specified in the fuel window from general vehicle and conditions information window.
Flow is calculated based on engine displacement, efficiency, boost pressure (if any), engine speed, and number of cylinders. The number of cylinders is needed only for the flow per cylinder calculations. Flow per cylinder is often very important for proper component selection and calibration (tuning).
