I'm sorry for all of the questions, but being a chemical engineering student with a minor in Mechanical and Petroleum Engineering for Oklahoma State University I can't help but question your methods. It's what any good engineer would want to know...

It very clearly violates the laws of thermodynamics.... You are using power from the engine to break water molecules into hydrogen and oxygen, then getting power back through combustion, which is basically a chemical reaction that combines hydrogen and oxygen where you collect some of the energy released by that chemical reaction which is the same energy you inputted earlier to break it apart. To get a net gain in energy, you would have to be operating at greater than 100% efficiency, which is impossible. Now consider that gas internal combustion engines operate around 30% thermal efficiency. Unless you are collecting energy from some type of thermonuclear reaction involving that hydrogen and oxygen, you are never going to be able to get more energy out of it than you inputted. The entropy of a closed system cannot increase beyond its inputs. This is first year physics and chemistry stuff...
Take a moment and ask what is the chemical composition of petroleum based gasoline. Next, ask what the thermal efficiency of using gasoline or hydrogen in an internal combustion engine. Please note at this point that Hydrogen combustion is far less energetic by volume than gasoline, then ask the chemist in yourself how this will increase the thermal efficiency of an internal combustion engine.
The ONLY reasons anyone EVER experiences a gain from HHO are:
1: The ultra lean burn state that they force their engine into, which could be done just as easily running a higher octane fuel, water injection or many other methods that would give back higher returns than HHO generators. The time this is most beneficial is at cruising speeds, where engine power can be significantly reduced without having an impact on the vehicles ability to cruise down the road. This is why things like Warm Air Intakes or variable displacement works so well....
2: The change in their driving habits that they subconsciously adopt when they are trying out this miracle fuel saving technology. EVERYONE does it, regardless of whether they think they do or not.
