I’m finally getting around to putting a post up about the HHO Monster Dual Dry Cell system I installed in my Mustang recently. The most difficult part about installing one of these systems is finding locations for the various parts. Now that that is complete, all seems to be working well and it’s a matter of time to figure out the proper tune to get the best MPG. Matt, the owner of HHO Monster, just replaced his older wet cell with a Single Dry Cell along with the new Pulse Width Modulator (PWM) that just came out, and immediately saw a 30% increase in his Toyota truck. I haven’t been so lucky yet, but I’m hoping with the new PWM and using a gauge like the Kiwi MPG or a Scangauge I can get the proper tune quicker. If he sees 30%, and the owner of the HHO Monster sister site in Italy sees 25%, I’m hoping to get similar results in the end. But for now, let me go over what I’ve done:

The Engine, Dry Cells, and Reservoir

Since my engine is the single cam 4.6 liter V8, we figured I should use the dual cell system to make sure we have the hydrogen output that might be needed. Each of these cells puts out about .8 of a liter per minute, with testing actually having shown to be more in most cases. I ended up mounting them under the front bumper on the passenger side of my car. If you look to the driver’s side, you might see the Amsoil Dual Bypass Filtration Systems, for those who have considered this from me as well.

The current supply reservoir tank is mounted next to the radiator reservoir and drains down into the cells, where the plates within each break out the 2 Hydrogen and one Oxygen (thus HHO instead of H2O), and the gas is then transferred back into the reservoir. The pressure from the gas keeps pressure in the system to help keep pushing water into the cells, while on the other side of the tank the gas is pushed into the engine. I picked this spot for the reservoir after remembering that the 2004-05 Mustang Cobras has a reservoir located here for their superchargers. The water has Potassium Carbonate in it as the electrolyzer so it is far more safe than many of the other systems using Potassium Hydroxide.

WARNING: Do not use Zephyrhills Distilled Water as your water source. When I first used this the tank filled up with suds that looked like a kitchen sink filled with detergent. Even with the tank 1/4 full, it filled it to overflow out of the top cap (when removed) and of coarse started to get pulled into the engine. We’re not sure why Zephyrhills is acting this way, but at the HHO Games, others commented about having similar problems and Crystal Distilled seemed to be the water of choice. Matt has used Publix Distilled with no ill effect. Once I mixed a new batch using Crystal Distilled Water, all was normal, no suds.
