I was watching horsepower tv last week and they had a fiero that made 240hp and got 40mpg using some kind of weird gizmo that heats the fuel or somethign like that. I want to learn more about this but i forgot the name of the guy that made it.

Just google the 100mpg carburetor. There are a few different designs out there.

I remember that. Something about using turbocharged hot air to spin two brushes and atomize the fuel more. It actually made sense to me.

That do nothing

I found some more info, it's called a hot air engine.

There once was a man named Smokey Yunik who besides being a famous race car driver was also one of the most innovative minds known to the practical world. He developed the hot air engine which using real world theories actually was tested by Hot Rod Magazine and produced 250 Hp from a 2.5ltr GM basically stock engine. The engine utilized a turbo/homoginizer that mixed the fuel and acted as a check valve to prevent the increasing pressure due to temperture from backing out of the intake stream. The temperature in the intqake manifold was 220degries F. This is below the Flash point of a properly atomized mixture. Upon entering the cumbustion chamber the mixture was compressed and increased to 440degrees F. There was no detonation or preignition. The car (A Pontiac Fiero) achieved 60MPG at 250hp.
This is very hard to comprehend when all our lives we are told that colder air is better. Unfortunately the efficiency of this type of thinking is a miserable 25%. The Hot air engine was at >75%. Proper control and engineering of systems can and will provide us with continuous advances in efficiency. Example using old formulas and thinking,How are the NASCAR 350CI engines producing 700HP with a maximum intake flow of 350CFM?

But then it is shot down again. But that was by car and driver and they cant even drive an auto accord right.

That description mixes two concepts to come to an inaccurate perception. Colder air IS better, with greater parts per million, upon entry into a one-way system. Hotter fuel is better, as it's more willing to ignite. To say that because hot fuel = good, therefore cold air = bad is faulty logic.

Even in the description the air isn't heated until after it's passed a valve, so benefits of colder air up to that point could still be realized.

You can run hotter engines leaner, but it wont save you that much

The trick with heating pump fuel, is to get it hot enough so it atomizes\xplodes more readily, but keep it cold enough that it doesnt start separating into it's components or boiling in the fuel line.

on the gas savers forums tons of people use hot air intakes to increase cruise MPG.

so this device is basically a non-intercooled turbo?

thats kind of a weird idea...... all i ever hear about fieros is them catching on fire........
