I am just now in the early stage of taxi tests. So far, temps are within limits. With the heads outside of the cowling there seems to be a greater cooling effect.
I have the same engine mount from Great Plaines and engine from them as well. Redrive is from Valley Engineering.
I have no baffling system under the cowling at this time. It seemed to complex of an effort because I have dual Bing carbs mounted near the heads. My hope is that with the heads outside of the cowl that would be sufficient. I am going to install two air inlets on the top of the cowl to direct air across the oil cooler. This should also improve overall cooling effect.
I will also install a prop spinner to smoothe air flow through the inlets on the nose bowl.
