Has anyone experimented with gasoline vaporizers?

I've been searching through youtube and saw that some people have done this and said they saw gains but they never really quantified the gains and so I don't know how well this works. I have a crazy idea of putting gasoline into the bubbler of my hho generator and get hydroxy + gasoline vapors all in one go. Explosive idea....

Here's a how to make a vaporizer... essentially it works like the bubbler for our hho generators.
