Ive seen a few posts where its been said that 140s are typical for 951s... Im just curious then if its really odd that my car has...

1: 160
2: 155
3: 155
4: 165

At 198k miles no engine or turbo rebuild? This test was done by a shop that specializes in Porsches.

Sorry these figures indicates only that the cylinders are equal. If for instance you have a good battery you will crank faster and get better figures. If you want to know more abot the condition you should do a leak down test. Or if the car runs well, just be happy and drive!

I has 145 on all four cylinders on my 951
a leak down showed. ( if I remember right)
#1 4%
#2 12%
#3 5%
#4 5%
all on a very cold engine at about 2 degree celsius
so compression is not neccecary the best way to tell.
