But the experiment was run at a university a few years ago on a Lycoming engine. I saw the data. I was surprised by how much the 50d F drop in CHT influenced the volumetric efficiency of the cylinder. Regards, George """ The measure is "manifold air temperature". If the manifold air temp is lowered 50 deg F, then the power would increase 5.8%. That is of course if the proper A/F is maintained. I believe there are to many variables to predict what a 50 deg cylinder temp drop would do to the manifold air temp. Craig Berland """ --- Incoming mail is certified Virus Free.
