Compression ratio calculation
Is there any way to calculate your compression ratio by using a compression guage? because i have one of those and i dont feel like replacing the gaskets for the valve covers just to look at a bunch of numbers.

Re: Compression ratio calculation (battsup)
No. "Compression ratio" is theoretical only due to the cam holding valves open as the piston moves up. Cylinder pressure is what a gauge reads and it's a relative value depending on leakdown, cam timing etc. There's no direct relationship.
