The static compression ratio of an internal combustion ingine is a value that represents the ratio of the volume of its combustion chamber from its largest capacity to its smallest capacity Compressed at an 8 to 1 ratio, you should get 6 x 8 = 48 PSI pressure if all the air makes it into the cylinder and then gets pushed out . If your vehicle has been running roughly or losing power, there may be a lack of pressure in one or more cylinders It will also estimate a dynamic effective compression ratio taking into account the cam timing and rod ratio .
