If you want an example of high-efficiency internal cooling, look to the Edison2. The intake (or exhaust, I forget) is a thin belt around the widest circumference of the body—where the air is moving the fastest.

Well, there are very few engines under legal driving stresses that I would see having enough heat to even come close to this accomplishment. It would be fun to try though
