cant help with the test but can confirm the compression ratio is 11.5:1
what is atmos? atmospheric pressure? and is abs absolute? small words for the non-talented pleaseHumbug said:11.5:1 * 14.5 psi (atmos) = 166.75psi abs no?
correct. don't forget you would need to subtract one atmos to obtain guage pressure...roobars said:what is atmos? atmospheric pressure? and is abs absolute? small words for the non-talented pleaseHumbug said:11.5:1 * 14.5 psi (atmos) = 166.75psi abs no?![]()

I like to know details mate. Anyone can take measurements and compare them to what's in the manual, I like to be the fool that knows why you do these measurements, and how they are calculated.smiley_666 said:i dont understand what all this is about. (i know about pressures etc)
you do a compression test. you do a wet compression test. you compare. if wet is better than dry by a bit more, rings are stuffed. if both are lower than everyone says they will be, youve got other problems (valves, head, gasket etc)
you dont really need to work it all out perfectly if you have a base to start with ~150ish psi
I agree, couple that with my $30 compression tester made in china and its going to be way off. But like I said, It's just for better understanding of the process.smiley_666 said:yes, but by figuring it out this way means not a whole lot. like i wrote above, it will always be out by a fair bit to the 'theoretical' pressure from the compression ratio
