Replying to: stacks125 (Mar 04, 2009 6:41 pm) Depending on how elaborate you want to make the HHO device, it can cost any where from $100.00 to $900.00. I found all the plans on-line (google for HHO) and then built it. Mine cost me $130.00. I used 2 seamless stainless steel pipes (2" and a 2 1/4" by 9" long) $80.00 plus a water filter from Tractor Supply $17.50 and made my own bubbler $10.00 and bits and pieces from AUTO ZONE +/- $15.00. I had an increase of power and a increase in gas mileage. I went from (21 gal tank) 290 - 320 miles and now 380 to +/- 400 miles if I drive like an old lady. If I want to spend a little more, I probably could improve that up to around 475 to 500 miles per 21 gal tank. AND yes thats 25 mpg. I went from 15 - 18 mpg to 18 - 21 mpg.
