if you do the math, this is just hype. gas only has so many btu's and it requires energy to move mass. the 20:1 air fuel ratio would increase gas mileage along with a vapor system, but this car should get no better than 50 mpg. to accelerate 1500 lbs at that rate you would need to burn alot more fuel. plus running that lean would be extremely hot and the engine wouldn't last long, you would have to limit the rpm's to about 5000 to keep the pistons from melting!

but fuel does need to be vaporized before it will burn. so lets discuss this. would heating the fuel to lets say 150 - 200 F before it is injected improve combustion? power?

and what would be any potential drawbacks with the most obvious being pre-detonation without tuning

i wish my car weighed 1500 lbs if you think it would need to burn a lot more to move 1500 think about an actual car that weighs 3000

well a motorcycle weighs about 400 lbs and get 50 mpg. an older dirtbike can get as high as 120 mpg if its small. but look at how practical it is, your better off with a motorcycle! you can't haul anything in it.

omg 1500 lbs, id kill for that weight in my car haha

anyone would kill to have a 1500 lb car.


as far as heating the gasoline before injecting it, you might as well run kool-aid in the tank, you'd make more power. the colder the fuel, the denser it is. the denser the fuel, the more efficient the burn. the more efficient the burn, better power and mpg.

yes colder fuel is denser, but warm or cold the ecu adds or subtracts the appropriate amount. but for ignition you need heat, fuel and air. granted the fuel is warmed rapidly as the piston compresses the mixture, if it was warmer going in, the explosion would happen a lil more rapidly. gasoline doesn't spontaneously combust until about 500 F but a spark will ignite it at -40 F. if it was heated to about 200 F before being injected it would vaporized much quicker giving a more complete detonation, and would be much cleaner also.

for power you want as much air as possible so you can add more fuel, therefore you want it cooler so it takes less volume. but fuel burns the same reguardless of temp. it's the vapors the burn not the fuel.

hmmm...... do you really know what detonation is? its when the fuel is injected and ignites prematurely, before the combustion stroke, and before the spark plug can light. that craks, chips, and melts pistons. detonation is bad, mmmmkay? if you want a melted piston, be my guest. just remember, thats why they make fuel coolers, NOT fuel warmers.....

lol yes thats pre- detonation, but that is most likely to occur at extremely high rpm's or excessive boost. if you have the proper octane rating you shouldn't have to worry about it but that is one potential problem i've thought of. for a daily driver though, it shouldn,t be to much of an issue.
