So of been researching the HHO thing and yes I agree that that cheap kits are not worth buying with all the problems that can accour but check out this one. It seems a lot more advanced, adjusts to throttle, build pressure to opperate more accurately, and only uses 5 amps max. how i get it. Also they cover how to adjust it right so engine is not running lean or rich, (extra temerature gauge).
Another thing reading down the article is i read that if the timing is off and knocking there actually is a way to like octane the hydrogen to correct like timing.
What do you guys think of this? Is it worth building and trying? It seems like they tell you the risk and thing you have to do to the internals.
Just let me know what you guys think of this.
