This calculates the pounds of air per minute (mass flow) that and engine will consume at its maximum rpm.
|cubic inches||the total displacement of the engine in cubic inches (see our cid calculator)|
|max rpm||the engines maximum rpm limit|
|volumetric efficiency||the volumetric efficiency is a measure of the efficiency of the engine moving the intake charge into the chamber and the exhaust out. Typical values are as follows:|
2 valve head – 80%
4 valve head – 88%
it is not unusual however to have VE’s of 95% or more in correctly built race engines
|air mass flow||the total mass flow of air per minute that the engine will consume|
