HHO is no joke. it really works....on a carb engine lol. i build thses at my work as a side job and a real good one( not the ebay ones) will increase mpg on a carb eng but inorder to do it on our xbs you have to change the ecu so much its not worth it. the more hydrogen and oxagen you put in a fuel injected moter the more the ecu will change the fuel. not worth it. but on lets say my 1978 doge van( v8 318) i went from 8mpg to 12-13mpg. witch is damn good for a 1978 20foot van lol.
