Was
the engine warmed up before the compression checks, or cold? It makes a
big difference on mine...

From:
JIMRHER@aol.com . . The
compression numbers I gave were very general and I can be more specific
here. Static compression is taken by blowing 80 lbs of air into the cylinder
and measuring how much it will hold. Using a two gauge setup and a
Calibrated orifice, I think you are allowed just under 50 lbs. When this was
done 1 year ago I had one cylinder that read 50 and the others were higher.
This time that #1 cyl. read about 40 lbs. The lowest was #6 at 24 lbs. #4
was only 44 lbs. and strangely #2, the one that I was so concerned about and
the one that was the hottest and most abused so to speak, was 56 lbs. the
highest of all. Also note that #6 is the front left cyl. that has the
intercooler in the baffle in front of it and did have lower CHT. This, to an
engineer, is a shoulder shrug, meaning even us Idiots can't answer what is
happening. . I also would like any other inputs? . Jim Hergert N6XE,

I wouldn't believe your mechanics
gauges. I think it would be worth remeasuring with another set on
gauges. -- Lorn H. 'Feathers' Olsen, MAA, DynaComm,
