What about running an external Oil cooler with electric fan, and duct the heat outside like a bilge vent

Ok see if i understand you correctly. the oil in the pan is 270+ deg. oil exiting the cooler is 190 deg. right. so oil going thru your motor is 190 deg. so lowering the temp in the pan wont do anything for you cause its going to be cooled by the cooler before going back thru your motor.

If the oil in the pan is getting that hot, something is wrong no matter what the temp is coming out of the cooler. So what can be causing it to get that hot? Heat tranfer from the underside of the pistons is a big heat source. If you are running lean, your oil will get too hot for your oil cooler to handle. Same with any detonation. What's the compression ratio and what gas are you putting in it. Aluminum heads? Water temp? Are you flowing water freely out of the the engine, ie. (2) 1 inch dia. hoses? Too large of a prop possibly lugging the engine. How much timing are you running? Sorry for all the questions, just looking at the big picture.

190F - 200F at cruise. About 220F and steady at 4500. It is when I run at full throttle 5300 - 5800 rpm (depending on prop) that the crankcase oil starts a steady climb. 1 min WOT crank case temperature depends on how hot the crank case oil already is. Starting with hot oil it gets to about 240F +/-.
