ok i just got a compression gauge and was wondering how to read it. for instance lets say i put it on the motor and it reads 150 how would i convert a number like that to 11:1. i am goint to check the compression tonight and just wanted to know how to convert it after i looked at the gauge and saw how it read.
another question
