There are very few cars than can have much of a low pressure under the car at high speeds. Low pressures under the car create suction and make the car stick to the ground - a very desirable thing. The new Ferraris have this. Even the Porsche 959 did not. In fact, for it's time, the 959 was revolutionary because it had zero lift. As groovy as our Type 3's are, we aren't in this class of aerodynamics :-). At high speeds, we get lift. As a sidenote, it is because of the high pressures under the car that leaving out pieces of sheet metal that seal the engine bay up on a Type 1 car is such a bad idea... > Anyways, if he > pulls air in front of the engine, it surely wouldnt be hot.

Compared to using typical aftermarket dual carb air cleaners, it's definately a better idea. But, it's hotter than the air he'd get from the louvers in the fenders. The air near the asphault tends to be hot. The transmission gives off its own fair share of heat, too (1 hp wasted by the tranny means 746W of waste heat... if we very roughly guesstimate ~3hp used by the tranny, that's ~2000-2500W of waste heat, which is a notable amount). I considered routing the intake air forward above the tranny for quite awhile. It seemed easier to fabricate :-).
