Which CR calculator is right?
I'm having a hard time calculating my CR. I've looked at 3 or 4 different sites, and I enter the same info for every Calculator, but they all give me different compression ratios! :smash:

These are the different CR calculators I used. Which one is right?! Does anyone have a trusted site they use and recommend?

All those online programs are is to give you a general idea, none are accurate. The only way to be certain is measure it mechanically.

I figured that, but the large differences between them was bugging me. Anyways, it turns out I misentered a couple of numbers :rolleyes: ... my bad
