I have seen talk on crankcase compression ratios lately. This is an excel work sheet I created to do this work. The blue numbers you input, the red numbers are out puts. If anyone would like a copy of this and more, you must email me directly, I'm not good with pms wpt1mike .com. If Forest were to challange me on any detail here, I will listen. This is how I have done this for more than 40 years. Maybe Im wrong, but you need a standard to start from. I can still be taught.
