Thoughts on vaporizing gasoline?

[Mustang Dave]

I read a second-hand story about someone who made a vaporizing carburetor as designed by Charles Nelson Pogue (The original "200 MPG carburetor) and installed it on his Ford Mustang. The car ran at a significantly reduced power level, and got 30 MPG.
I prefer to have full power available when I put the spurs to my "pony", but I wouldn't mind 30 MPG. Oh, wait, uh ....

If the gasoline hasn't completely vaporized by the time of ignition, The combustion temperature will most likely vaporize what un-vaporized gasoline is left in the mixture.

I have even tested a device that completely vaporizes the fuel on a heated surface, eliminating fuel droplets altogether, and the economy improvement was tiny (1 - 2% at most).

That is what other experiments I have read about were saying too.
All were claiming 3% or less.

Which is about what direct injected gasoline engines generally gain? Maybe they are on to something

35mpg + a 3% improvement is 36.05mpg or 1.05 mpg savings
maybe on a 48mpg car it would be better - that comes to 49.44 mpg or a 1.44mpg savings.

Crunching the numbers also reveals that a 12 gallon 35mpg car you would drive a extra 12.6 miles & a 48mpg car you would drive 17.28 miles further down the road.

It is certainly not novice experimenter friendly. Its more like a novice experimenter exterminator or skin modifier..
