Normal compression on a gasoline engine is about 125 psi.
With a compression gauge.

10 psi
To determine the compression ratio from the psi (pounds per square inch) reading of an engine, you typically need additional information, such as the specifications of the engine, including the displacement and the type of gauge used for the psi measurement. However, a common method is to use the formula: Compression Ratio (CR) = (Absolute Pressure in Cylinder + Atmospheric Pressure) / Atmospheric Pressure. For example, if the atmospheric pressure is approximately 14.7 psi, the absolute pressure would be 155 psi + 14.7 psi = 169.7 psi, leading to a rough compression ratio of about 12.5:1.
110 to 120 psi
Should be 110 PSI
85-125 psi is acceptable.
It should have a minimum of 70 psi.
480 psi minimum
150 psi should not vary by more than 10 psi between cylinders
