 Mr. Lamar,
Personally, I think a hard anodized finish on an aluminum pulley would
be superior to teflon. Combining the small air evacuation holes on the
dedendum of the pulley and carefully designing the 'spokes' of the
pulley to behave like fan blades could go a long way toward dissipating
the heat. Adding dynamic balancing complicates things, assuming that
dynamic balancing refers to some sort of balancer like an automotive
crankshaft harmonic balancer.
 I honestly have no idea what it would cost to have a die made up to
stamp the tooth form into 4130 steel, but my hunch is that it would be
more expensive than either custom pulleys or modifying existing off the
shelf items. Just my two cents worth...I sure would like to see a rotary
powered plane compete at Reno.

 P.S. My experience with AOL was that they were easier to get rid of
than herpes, but not much less annoying.
