Question for all you smart people out there......How to calculate the compression ratio of an engine that is complete? I know compression test gives you psi, but what about the overall ratio?
There may be a way to test it with some sort of sonic tester that can measure volume, but it may not be affordable for the home mechanic...
I have a how to on measuring compression on any engine to see what your combo does... It's a simple and cheap method that can be done in any home garage...
