Straight from the Evo 9 Service Manual:

Cylinder Compression:

Crank the engine with the throttle valve fully open and measure the compression pressure.
Standard value (at engine speed of 250 r/min): 1,000 kPa (145 psi)
Minimum limit (at engine speed of 250 r/min): 637 kPa (92 psi)

Measure the compression pressure for all the cylinders, and check that the pressure differences of the cylinders are below the limit.
Limit: 98 kPa (14 psi)
