Update on my airplane, I now have four flights on my engine after replacing the seals. Last night I was up for an hour. At 5000msl it was 28C temps stabilized at 197(water) and 188 oil. I still need more power. I am only getting 5000rpm static which makes for very shallow climb outs. In the air, I'm getting between 5500 and 6000 rpm at about 140mph (no wheel pants or fairings).

 

I did an experiment with a 12" fan mounted behind the radiator. The fan keeps the water temp under 190 on the ground, but caused about a 10-15 degree increase in the air. So now I'm thinking about mounting a small radiator with a fan under the engine.

 

My next project is to rework the intake for more static rpm.
