Perhaps if I had the rotors ceramic coated the coolant temps would be higher and oil temps lower but, my oil temp was at 160-180F and my coolant temps were at 200-210F, so I don't think ceramic coating would have done me much good. My understanding is that it shields the rotors more than any other component from the heat of combustion - so would probably help keep oil temps cooler.

The biggest problem the rotary has is excessive wall area for it's chamber size. While it may or may not help temps, I don't know, it should improve the overall efficiency.
