Compression Ratio.
What is the stock compression ratio of the 3rd Gen. Cummins ISB 5.9L?
Is it the same for all 24V Cummins engines? How about static compression in each hole?

Taking the 17.2:1 ratio if you figure up how much psi you should have on the compression stroke what would it be? P1V1=P2V2, anybody know what the volume is when the piston is all the way up, I think you would have to account for volume in the head as well. I have seen #'s ranging from 300-400 psi on compression testing. What's everyone's take on the normal number to get assuming rings, head etc. are all working perfect. Jay
