calculating ve or cfm

anybody have a clue. i know the equations but you can't calc one without the other. so if anyone knows either one that would be great. even a stock number is fine.

If you are thinking about calculating your actual VE, you will have to measure the actual CFM.

Otherwise, you can approximate VE from engine output (HP).
VE = (HP x 792001.6) / (AP x CR x CID x RPM)

VE = Volumetric efficiency
AP = Atmospheric pressure in psi
CR = Compression ratio
CID = Cubic inch displacement
RPM = Revolutions per minute

that'll work. thanks gary!

A buddy of mine made a calculator if you know a few things about you engine.
