For vaporization of gasoline
Okay. After a couple months of experimenting, I've come to some conclusions.
Exhaust gas is perfect to force vapors into the engine. It's hot and rpm is proportionate to pressure which matches intake just like a turbo.
Tube / pipe heaters are the most efficient use of electricity to vaporize gasoline.
