Re: What did you do to your boss today?
Using 170 PSI as your target;
Standard rule of thumb on compression tests is as long as the cylinders are within 10% of the highest to lowest, you are O.K. 17PSI from the highest of 170 to the lowest of 155 is still within acceptable range, your largest difference is 15 PSI.
GTMikey said:So cylinder 1=158, 2=162, 3=155, 4=160, 5=170, 6=162, 7=162, 8=170.
My understanding is that 170 is the pass pr good number. Any thoughts, opinions or knowledge out there??
