Sort of in the realm of aerodynamics...

Tatra made a V8 T603 race car, and removed the parasitic load of the cooling fans from the air-cooled engine.

How did they keep it cool, you might ask?

Those big honking exhaust pipes are actually exhaust extractors, basically venturis that act something like the "air multiplier" on those Dyson bladeless desk fans to suck air though the engine. Voila, an extra chunk of HP not used by the cooling system!

I always wondered if someone could run something similar on a air-cooled VW engine.
