Cylinder Compression values

Post by reggie_001 »

Just wondering if anybody could tell me what readings I should expect if I did a compression test on the cylinders of a 4.0 litre Range Rover S 2000 model.
Thanks in advance.

somewhere between 140-160 psi (hot) depending on whether its a highcomp (9.?) or lowcomp (8.23) motor.
84 Rangie, 3 inch spring lift, 2 inch body, Megasquirted 4.6, R380, rear Maxi, 34x11.5 JT2s. Simex FM installed.
