Well, just to try and add a few cents worth. I am not rreally thinking at the moment, just writing whatever comes to mind, so dont moan if it is a load of hogwash.

Exactly how can you overcool a aircooled engine with a porsche fan. Ok, I understand that the oil has to get to operating temp, but isnt the stock oil cooler removed to make space for the porsche fan. So if that is the case, the operating temp of the oil is governed by a remote cooler. If you end up making the barrels and heads really cold, is that going to make much difference, not like it will shrink to the point where your assembly tolerances will become zero and things start to sieze -or am I wrong? Think about it. There is always combustion happening, so the insides of the cylinders will still be warm.
Oil also starts to break down at temps above 90deg C (maybe higher for automotive oils, cont find any specs), so the cooler the cylinder, the longer the oil will last. The temp of the piston wont change that much, as it is mostly cooled by splashed oil and it is heated by the combustion.

Dont know what you guys think or know, but I am open to suggestions, ideas and arguments - lets wake this forum up!!!
