Replying to: mrmouse3 (Jun 10, 2008 10:20 pm) that sounds like a great idea. Would you be able to let me in on some info on what it takes make it run on hydrogen and did you notice any power loss?               Thanks Stacks Replies to this message: mrmouse3 (Mar 07, 2009 5:27 am) dabell7 (Oct 04, 2009 6:53 am)

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.
