These worked (sometimes) by leaning the overly rich mixture that carbs provided. Most ignitions couldn't burn a real rich fuel mixture back then. Sometimes they worked by decreasing detonation and pre-ignition, allowing the mixture to burn when it was supposed to. They did not help a well tuned engine. With modern EFI and electronic igniton, you would see no improvement, either.Back in the early '70's at the Army Aviation Center (Ft Rucker, AL) I knew some guys in the test and engineering section. They got a set-up from J.C. Whitney that would inject water into the fuel to "hydro-ize" the fuel. Turns out they could make the same thing with some peanut butter jars and tubing. They did some tests with their vehicles and determined that yes, it did work under the right circumstances. It was like driving in the rain. The 'hydro' just increased the density of the air. It's a simple concept that some folks want to be paid a lot of money to provide it to the public.
If you bought all those gadgets that were guaranteed to increase you gas mileage and hp, you'd probably have a perpetual motion Spyder!
