Toyota Tundra Forum

good read, they made some good points also, i believe they were "over thinking" it some what though, any who, we'll try it and see what happens.........

all it can do is blow up...............lol.....

Anybody else catch this video on Toyota Hybrid Testing?

I tend to be a big believer in the law of physics, but I'm all for a cleaner energy delivery method.

10K psi hydrogen storage and a range of 300 highway miles. Interesting and good if you don't travel too far. But I'd rather see the HHO technology take off since you store water instead of hydrogen.

I have installed a home made HHO generation system on my 2007 Tundra. Not all systems require high amps to generate enough Hydrogen to make a difference in your mpg. The Tundra has enough space between the bumper and the radiator to put several generators which all run on 2-5 amps each and get excellent cooling so you can run them with more catalyst for higher production output. Without modification to the MAP sensor, the system has provided a 20% mpg improvement in city driving and a 25% mpg improvement in highway driving. I expect this to increase when I can adjust the computer to account for the air coming through the generators. The most significant thing though is the lack of typical exhaust smell. Since the hydrogen is causing the fuel to burn more completely there is less fuel going to the catalytic converter and therefore less emission out the tailpipe. The engine is also running smoother and quieter than before (I can actually hear the bubbling from the generators over the engine noise in the cab, it is so quiet now).
There are many different designs for the electrolysis cathode/anode and each one has it's own characteristics which affect resistance and amp draw. The key is to optimize this to utilize excess energy in the engine without having to increase the alternator which would have a negative effect until you reached the top of the curve again.
When you make modifications to the computer to adjust the air/fuel ratio then you should see some reduction in power but that should only be felt when towing or climbing hills. That is why the MAP sensor enhancer allows you to turn off your modifications if you are in those situations and maintain full power. The rest of the time though you will have much better mpg (very similar in thought to how they turn off 4 cylinders on the US car makers V8's to improve normal highway mileage).
In the 2007 model Toyota removed the secondary vacuum system on the left side of the engine which left an unused vacuum port under the plastic cover over the intake manifold. This made it very easy and simple to add an HHO system to the engine (and you can remove it when you need a servicing by Toyota). I tied power into the fuse box next to the battery with an ammeter and kill switch in the cab for safety. I tested each generator on a battery charger first to adjust the catalyst (baking soda) to the proper level so I didn't exceed 5 amps when it got to its highest charging level. I need to add more water/catalyst about every two fill ups.
I would recommend for people to look into this technology if for no other reason than to reduce your emissions. But the mpg gains are real.

Welcome sboynton. You've came to a great site, take a minute and introduce yourself and let us know a bit more about the model and such Tundra here http://www.toyotatundraforum.com/new-member-area/

I've never been much on science but have read a little on the HHO. You seem to have had a really good experience with it. One question I have to you is. Can the HHO cause permature wear or failure with the rings or any other componet in the engine, which normally receive lubrication 100% of running time from gasoline.

Hi sboynton. I'd love to see some pictures of your setup. Have you tried running the engine on only HHO?

Thanks for the welcome.

On the wear question - my system is fairly new so don't have any personal data, however others that have installed these systems report no increased wear on the rings since there is still gasoline being used, just less of it. But there have been many reports that oil changes don't need to occur as often since more of the gasoline is being burned and not deposited as gunk in the engine. When people have installed these systems on older vehicles they have reported that the engines start to clean themselves out and run like new again. It makes sense if you think about the Hydrogen and Oxygen gas being ignited in the chamber which produces an output of steam which then travels through the exhaust system.

On running the engine on only HHO - the system does not produce enough Hydrogen on demand to make this possible. In order to do that you would need a pressurized tank of Hydrogen like Toyota did in their Canada run. This type of system is designed to lower your mpg using a hybrid methodology only. That being said though, people have run small lawnmower engines on just the HHO produced by these systems in their garages.

It makes sense when both are mixed. This sounds like a DIY thread. This would be a great lunch on me conversation. So I'll ask. How do we build the system? Or wheres the best source with diagrams and such on the net? Almost forgot, where here.
