I know most people here are using HHO for increased fuel economy, but I'm wondering if anyone here is using HHO as a power adder. If you get the right tune, the more complete burn and advanced timing should see more power from the same amount of fuel.
Anyone here using HHO purely to get more horsepower? What sort of gains are you seeing? and on what type of car with what HHO setup? oh and what other performance mods?
