No matter what your method, will always consume more energy splitting the hydrogen and oxygen than you can can get back. You can't cheat the laws of physics.
Well... That's not quite true. Extensive research was done, and it was shown that hydrogen can extend the lean burn limit of a gasoline powered internal combustion engine...

Sure the kits don't work, but the kits don't alter the A/F ratio of your car.

If you could find a way to trick your car into running lean with a good hydrogen generator, you would see small gains. You'd have to map the A/F ratio against load though. It'd be hard but doable.

FOr some reason, the wikipedia page on it isn't showing for me. However, IIRC correctly, hydrogen fuel enhancement can allow a gas engine to run as lean as 25:1 at low loads.
