| Subject: | compression tests |
Just out of curiosity, I did some compression test comparisons using a dynam
ic compression tester. =C2-You know, the kind of tester 'engine' guys use
to determine the health of cylinders. =C2-
On a ported and polished, high compression, O320-E2G LyCon engine with 55 ho
urs on it,=C2-
79/80 =C2- =C2------ > 145 lbs
79/80 =C2- =C2------ > 145 lbs
79/80 =C2- =C2------ > 145 lbs
79/80 =C2- =C2------ > 140 lbs
On a stock O320-E2G with 1200 hours on it
76/80 =C2- =C2------ > 100 lbs
77/80 =C2- =C2------ > 100 lbs
77/80 =C2- =C2------ > 100 lbs
78/80 =C2- =C2------ > 110 lbs
Now I need to look at my engine.

Not surprising with the better breathing engine and the higher compression
ratio. I doubt if very much of the difference is due to the lower differen
tial compression numbers.
