Hey Ren-Man,
Thanks for having us over last weekend. Lena and I had alot of fun.
Sorry to bear bad news, but I don't believe that you can actually get your compression ratio from a compression test. I know because I've already tried it. The test will only tell you maximum cylinder pressure in PSI. Valve timing and other factors skew the test greatly. Compression ratio can be calculated by the pencil and paper method if you know the chamber size of your heads, thickness of your head gasket, your bore and stroke, and piston head design. I might even research the formula for a jar of your famous hot sauce..........ha ha ha
BTW, I think I have a compression tester around here also. I'll look around for it.
