That's pretty cool, man! Where do you introduce the HHO gas into your motor? I always went in with a tee on the brake booster vacuum line.
How many Amps do you run and where do you Mount the generator? I kept mine ahead of the radiator but behind my grill to try and get a little "windage". That thing got damn hot running under the hood.
Your design sounds cool. Do you have an mpguino or something for your car?
Enough questions already
Thanks,
Victor
