I have had many of the overheating problems of other Europa 912 Europa owners: replacement of 2 ignition coils ($300) each, and a voltage regulator that appears to be failing. My primary problem was trying to decide if the difficulity was restriction of air in or air out. My water and oil temp were within normal limits. Due to the fact that I am not using the standard engine air inlet this cleared up the center of the top cawling. I added a air scoop, like on muscle cars - from Autozone. The air scoop was installed backwards from normal installations - this develolped a low pressure air under the cawling to draw the hot air out.
Last week I did a high speed taxi run. The air temp was 98 in the shade. I had the plane outside for several minutes and the under the cawling temp was 119 before starting the engine, I checked the temp after getting the plane back to the hanger after the run and the temp was 114. On a typical flight the temp jumps up 25 degrees from ambiance. After turning the engine off it is still necessary to open the two inspection doors on the top cawling.
I will try to enclose some pictures. If it does not work and if anyone is interested I'll get help from one of my electrical engineers son.
