Rich;
True, most is gained by keeping the crank out of the oil but there are
small pumping losses as air is pumped from one cylinder to another as
pistons go up & down. On average the volume is constant but the
situation in the crankcase is anything but a static condition. Think
7000 RPM air pump.

As long as there is pressure on the bottom of pistons going down, there
will
be exactly the same pressure pushing pistons on their way up. Has to be.
I
always thought (Without any real knowledge) the HP gains came from
keeping
the crank out of the oil.
