Throttle fully open. Fuel pump relay removed. Engine warmed up to working temp.
7 cranks on each cylinder - approx 185 psi on all cylinders. I was happy with this.
Car has 153k miles on it.

Hello Everyone,
I am curious what kind of compression numbers to expect from a US Spec E28 M5. Also, Is the procedure the same as doing compression on other cars?? I assume you remove coil wire and push accelerator pedal to floor and crank for about 5 seconds?? Any info is appreciated.
