Hot air intake

damn that seems like a pretty sound idea too, heat vaporized feul is highly volital and really should produce more bang per quantity

You'll notice that the heated air theory was in relation to carbureted engines NOT mass airflow fuel (MAF) delivery systems. Carburetors meter fuel strictly by airflow volume, whereby our MAF systems use airflow and the density of that airflow to basically determine the amount of fuel delivered to the cylinders. As far as the warm air assisting vaporization, that's apples and oranges........our systems deliver pressurized fuel right at the intake valve using injectors that atomize the fuel into a fine mist for very easy vaporization. The standard carburetor used on most cars did have problems with atomization just by design, especially under certain operating conditions.

^^so in theory this only makes sense in older designs that are not as computerized and dont have modern fuel injectors??

still an interesting concept but not applicable to modern 4-bangers?

just making sure im clear on what u mean by that post

I remember reading about it a long time ago. It's really a great concept and had better fuel saving and emissions reducing effects when compared to most of the power robbing emissions stuff today.

Aside from it only working on carbureted engines though, if anyone really tried to bring it back and make it work they'd be bought out in an instant by the oil companies or something stupid like that.

Well comparing it to modern motor designs isn't really fare, this idea was never given the thought and years of work that every other motor has.
that being said yeah it was on a carb.ed engine and there would probably be no way ( other than complete reinvention of the ECU and injectors) to make this work on your car but the way injectors atomize fuel is different than Vaporizing fuel with heat. The atomization spreads the fuel out in the air but still keeps it in a low temp. less reactive range. The vaporized high temp fuel, being thats it all ready hot and will need less energy to reach combustion, should require less fuel to reach the same level of force during combustion creating a more effieciant engine.

or am I wrong??
