compression ratio compared to compression PSI | Hot Rod Forum

If your compression ratio is 12:1 theoretically that means the compression is 12 times atmospheric pressure. (atmospheric pressure compressed to 1/12th its uncompressed volume) At sea level there is 14.7psi of atmospheric pressure. 14.7 x 12 = 178psi. Not far from 185 and the compression tester could be off that much.
