I was told the process of checking the CI of an engine at the track is called PNG'ing but when i went online to fine out information on it could not find anything relating to it. Could anyone point me in the right direction with some info on it, or tell me a little on how its done
Thnaks for anyone that can help

To find the CI you need to do this. Bore x PI (3.142857) x Stroke x Number of Cylinders
Example: Bore 3.5" x PI = 10.9999995 x Stroke 3.97" = 43.669 x Number of Cylinders 8 = 349.35 CI This is the basic rule for displacement. However it does not account piston shape IE: HEMI VS Blower type, or any other combustion chamber variables.
