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 CylindersExample: Bore 3.5" x PI = 10.9999995 x Stroke 3.97" = 43.669 x Number of Cylinders 8 = 349.35 CIThis is the basic rule for displacement.However it does not account piston shapeIE: HEMI VS Blower type,or any other combustion chamber variables.
thank's for the post and i will try it good job guys.Performance Chips
