RE: K&N filters.

Spin on filters flow outside in. Oil goes into the ring of small holes around
the inside of the gasket and pushes open the check valve (where equipped) and
exits through the center hole. If you connect the oil lines to the mount
backwards, there will be no flow. They are about $10.00 retail.

The K&N is a 20 micron absolute (not nominal) element, that flows 16 GPM at
70 PSI. This is way more that required for a rotary. While there is no doubt a
pressure drop across the element, I cannot detect it with a conventional oil
pressure gage.
If you can find a better performing filter with a 550 pound burst can, please
tell me about it. I run two in parallel on the race car for 32+ GPM
capability at 100 PSI.

The SAE dirt holding capacity or efficiency when half full of dirt is of no
value as a requirement. I discard then each season. An element half full of
stuff, means that your bearings are gone. Bearing stuff is real big. Even a Fram
can stop a bearing, or a washer, or a screw driver. It just cannot protect the
bearings against contamination.
