Post from 1-10-2008 (My own HHO experiment) + analysis
Here is a repost of my HHO experiments earlier this year.
I now have 3 cells and a bubbler under my hood as we speak! (er blog)
--------------------------------------------------------------------------------
I have been experimenting with this concept for about 4000 miles now.
My setup includes 3 seperate HHO cells (Jars) and a bubbler. I have 2 circuits each operating off a 30 amp circuit breaker and relay. One circuit is direct to a single cell and the 2nd circuit feeds a pair of cells in series. Each cell has its own 12v dc fan and I've even installed a forced air cooling system.
I have a day/night video camera setup under the hood to monitor the system on my 7" touchscreen.
2 cells are fed through a bubbler and then into the vacuum plenum and the 3rd cell feeds directly into the intake.
The system is now operational only when the car is running (killed battery once by leaving the circuit on by accident). The entire circuit switches on when power is supplied to the fuel pump. I installed a failsafe circuit by running a wire to the switched output of the fuel pump relay then to the pair of 30 amp relays feeding the HHO system.
I even have a fan to cool the relays and fuses. I also have a total of 3 video cameras installed in/on the truck. Front cam (Behind grill), Rear cam (attached off the 3rd brake light), and a cam under the hood to monitor the HHO system (and watch the bubbles).
Fail Safe switched circuit currently runs:
(2) 30 amp relays with circuit breakers
(3) HHO cells
(4) 12v dc fans
(3) video cams
Back up sensor system
12 volt distribution rail for interior accessories
The HHO system also includes a temp gauge and amp meter. The HHO system in operation pulls 30-50 amps. (Depending on operating temperature)
I am still actively experimenting with cell and plate designs making changes on a daily basis. I just replaced my O2 sensors after 248K miles yesterday so the true tests start today.
No exposions yet!
End of original post.

Postmortem: My wife made me remove all the HHO cells before she would ride in the truck.
Analysis: I found no significant mileage difference. I believe that my homemade cells leaked air into the cells under vacuum and allowed it to dilute the gas. Also on my first gen Exploder I have no way to reprogram the PCM to offset the H20 released into the exhaust.
Here are pics of my first HHO cell in operation and a pic of the cell viewed by the underhood cam. Notice the A/F guage is dark.
I'm really glad more people are trying this concept. Just don't tell your wife.
