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.

degrees)
