Dynamic Pressure equations.
Im trying to find out the equation for dynamic pressure vs compression ratios. Reason why im asking is, I have 10:5.1 compression pistons. I want to run a compression test on the cylinders to see where I match up with the compression ratio. Also why is it so important to stay at 185 psi ?
Im trying not to over cam my bike and hold to the 10:5.1 ratio. (Max Power).

My build as listed in my signature, has 190 CCP for each cylinder...............and I have some hot-restart issues in the summer time.

RE: Dynamic Pressure equations.
I have200 lbs of cranking cylinder presure, without comp. releases id be F**ked all the time!
The other issue is timming, and a true 10 to 1 comp. or higher you need to drop alittle timming for the detonation issues that will arise!
