Bill, not quite certain how it do that. I can understand that the
rotor being coated would tend to lessen the amount of heat the
rotor would absorb and therefore keep the temp of the oil ,which
cools the rotor, down. But, it then seems that heat has to go/do
something. I agree there should be some increase in overall
efficiency by keeping the temperature of the combustion chamber
elevated. However, I believe that heat has to go somewhere and I
think you would see a rise in coolant temps. But, that's just
speculation on my part. Not saying there aren't some advantages
to having them coated - but if like most things there are probably
some disadvantages as well.

Ed, wouldn't the heat go out with the exhaust?
Didn't Al run some numbers the last time ceramic coating went around the list? I remember him predicting a 15 degree delta, but I can't recall what the delta applied to.
Al, when you ran those numbers, were you able to take into account that the smoother surface would possibly help create a laminar boundary layer at the rotor face.
