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?
