An aluminum casting with a bunch of fins inside and out would be ideal
but a bit heavy. It would not do all the oil cooling but it might help.
I'll draw something up when I get a bit of time.

Hey good idea, maybe I'll try that. Aluminum with a bunch of fins might
still be lighter than the stock steel pan I have now. Design it so that
it takes no more "footprint area" than the stock pan and also does not
exceed the external 3d dimensions of the stock pan so us guys already
flying can use it.

There are some large heat sink aluminum extrusions with large fins available
in the electronics world that might be welded together to form the pan.

BTW Did you get the manometer?

Yes, it just arrived. Haven't opened it yet, just put it in the car to
take to the airport. I just got back from a trip to the coast. Left
yesterday afternoon 95F. Throttled way back to 4900 RPM after the first
1000 feet, very slowly climbed to 5500, oil temp went to 230 and even at
the low RPM setting only dropped to 220.  Just not good enough...

Hang in there Perry you will figure it out. Let me know when you get the
manometer installed and I will ship the camera up or bring it up myself.
