Need help in calculating Engine Air Flow and Specs Explanation

[QUOTE="jack action, post: 5474256, member: 240508"] VE is calculated by dividing the actual measured airflow by the theoretical airflow that can go in the engine (displacement X rpm). So you either need to actually measure the airflow of the engine or used a complex engine cycle simulator to do the calculations. There are no easier way. The intake design (cross-area and length) can affect airflow by taking advantage of the pressure waves created by the engine's cycle. Although, on the intake side of a 2-stroke engine, it is not of a big effect because the crankcase is part of the intake system; So it shouldn't make a big difference to alter your intake design (as long as you don't restrict the flow).
