Hi Guys,

The compression test on my 993 RS reads 158 psi average with lest than 15 psi deviation. The PPI says this is within manufacturers tolerances.

How does this sound to other 993 RS owners?

9m - what are your thoughts?

Cheers

I haven't done a compression test on my RS, but if you don't get any replies I can find out from GT-One who service my car.

Thanks randeria,

Might have to take you up on that offer mate. My PPI showed 158psi average across 6 (no deviations greater than 15psi between cylinders), and was stated as within "spec'. However with a 11.3:1 ratio you would think that it might be higher?

See how you go and thanks in advance.
