Hi,
Just wondering if anyone can explain how to convert between the compression ratio of an engine to the psi I should get from a compression test.
In other words, I know a stock healthy Micra engine is 9.5:1 and produces 180psi per cylinder.
I'm getting around 190psi on my high comp 1.4 (with some 272 degree rally cams), how do I translate this into a XX : 1 compression ratio?
I'd really appreciate any help, thank you!
