oops, yes it is divided by pi. That is why I should not reply to things when
almost brain-dead. Thanks for the correction.
And true, it will not get you the greatest wear, but it is at least a
ballpark figure (I also think the ring will not perfectly follow the contours
of the cyl, since when it is causing the wear (on the power downstroke), it
is being pushed outwards by the pressure of the gases on the inner surface of
the ring (at least on most ring designs w/ bevels on the upper inner surface)
and therefore being deformed to match the slightl out-of-round condition on
engines w/ cyl wear)
Take care, all!
