How do you figure out the compresion ratio useing a compression tester. Thanks

 

you realy cant. differnt cams produce differnt cyclinder pressur. a cam with low duration will pruduce lots of cyclinder presuer and have lots of bottem end torque. a high duration cam prduces less cylinder pressuer cause the valves are open longer and bleads off more cylinder pressuer, so you need high compresion pistions to raise your cylinder presuer so you dont have a soggy bottem end. hope this help
