Have you considered that an extremely >lean or rich mixture would give you the same effect? How would it do that? As soon as it fires it generates heat. Not trying to be flippant, I want to understand what you mean. I realize that cooling is realized with an extremely lean mixture by causing less power and therefore less heat to be generated. I also understand that an extremely rich mixture results in unburned fuel that carries away some of the heat. Is this how it works? Please correct me if I am wrong. OR=20 Are you suggesting that in my every other firing scenario a lean or rich mixture working its way through a non-firing face would cool the rotor face more than just air at the expense of fuel consumption? How fine grained is the mixture system with fuel injected engines? Is it possible to vary the mixture for each face of the rotor? Something like "normal-lean-normal-lean-normal..." -Randy
