I don't think you'll see any gains from water injection on a modern engine, unless your engine is running with retarded spark, you won't make more power or get better fuel economy. These systems worked great on carbureted, high compression muscle cars when premium fuel became hard to get. Water injection doesn't give you more energy, it subtracts energy from the combustion process, limiting peak temperatures and allows you to run MBT spark if you run low octane fuel.

You hit the nail on the head Dog.

If there is a Wikipedia article to be referenced in regards to HHO/water to hydrogen systems, it should be this:

Because these snake oil salesmen are breaking #2.

Re: Water Injection Installed

Well I had a water/methanol kit on my dodge ram and it worked alright. Its a pain to fill the damn tank up all the time though. Looked back at the site and to my surprise they offer a kit for the H2. Planning on getting it.:)

No pics, u guys would proboly laugh so hard you would fall off your chair.

One thing is for sure though, running the water injection makes 87 octane fuel work real well with the supercharger....

Re: Water Injection Installed

the part I find interesting is how the idea of water injection has once again come round to become a objective cure.
I remember back in the `70s when people were force feeding this crap and blowing up engines left and right. the only thing I can say the water does effectively is remove carbon deposits on the combustion chambers and pistons.
its negative effects are little more of a concern.
cast pistons can't deal with the incresed flex of the domes for long before they fail from fatigue. the other fine atribute of water in fuel is noted as "putting out the fire". the catylist will actually suffer on the long term because it can't make heat effectively. it will plug up and cost you more then any amount you saved. so fair warning on the "benifits of water injection".

Re: Water Injection Installed

did you guys look at the performance gains on the dyno charts on the link?? Like I said I ran one on the old dodge and it ran fine the only problem is filling up the damn reservoir and apparently they have a bigger tank now???:)

Re: Water Injection Installed

There are others that know allot more than me on this subject but, water has been injected into jet engines to cool and make more power for a long time. It was used in WWII in many planes but, the 2 most popular I can recall were the P-38 and P-51. Both running superchargers although the P-38 in my book was a turbo as it used exhaust to turn compressor. Even the Zero ran a water injected supercharger that turned on belts off the crank.

If you have the water or water/methanol inj. set for WOT only and do not have a 40lb. lead foot even a small tank should not be to inconvenient. Some use a progressive inject system but, are harder to tune and calibrate to prevent washing the cylinder walls clean before ignition. Well that is getting in deeper than regular street rig needs.

I'm a fan of inj. many things through fuel for diff. appl. Later my goal would be direct cyl. injection which would be most powerful and most eff.

Good Luck to ALL no matter for whatever purpose and experiment. It is the only way the rest of forum get to learn something new is because one member took the chance and time as it does take time and money.

Re: Water Injection Installed

Ducky if I'm responding to you when you were making your short comment after my statement concerning something else I do not mean to even begin to start crap.

If you pay close attention to my remarks about injection it was not about mpg but, about power. I feel whatever you inj. as long as it creates power then you need less throttle to maintain desired speed. I'm yet to be convinced that you can gain huge mpg increases inj. water until I see enough people getting it done. But, I do know that someone cannot get something new going without trying. Most increase in knowledge has come from people going out onto the edge of the envelope.

Now again I feel inj. or just additional cool air blown right on intake or heads as far as I know should help to increase power which can create the opportunity to use less fuel to maintain the same perf.

I hope I have clarified my thoughts as I hope to encourage experimentation on all vehicles in any way and for whatever reason.

WATER INJECTION
This technology was developed during World War II to provide emergency sprint power for turbosupercharged fighter planes. At altitude, there is less air for cooling engines. The turbos, however, cram air into the inlet at manifold pressures nearly the same as those at sea level. The compressed intake air, heated as it goes through the turbos, makes the engine even hotter. Spraying water, or a water-alcohol mixture, directly into the intake lowers the combustion-chamber temperatures. This permits substantially more power for brief periods. Several manufacturers have attempted to apply this technology to automotive use. We ordered an AquaTune from a classified ad in the back pages of PM. "AquaTune is like no other water injection system in that it is, in actuality, a fuel cell hydrogen processor. It produces hydrogen-rich bubbles before being introduced into the engine draft." An "ultra-sonic barometric pressure chamber giving off ultra-sonic frequencies" apparently splits water molecules to create hydrogen bubbles. Anyone who can explain that, please call me--I'd like to make some hydrogen ultrasonically from water and solve the energy crisis while simultaneously eliminating global warming.

It was relatively easy to install the AquaTune, although we did need a few feet of our own vacuum line. (What do you want for $399?) Unlike the pump-fed water-injection systems on P-38 fighters, the AquaTune relies on intake manifold vacuum to pull distilled water from a plastic bottle and into the manifold. So, at periods of wide-open throttle, virtually no water should enter the engine.

THE DYNO SAYS: With the AquaTune adjusted according to the instructions, the test truck gave us 20 fewer horsepower and about a 20 percent poorer fuel economy.:OWNED:

THE MORAL OF THE STORY
We've tested nowhere near all of the fuel-saver gadgets on the market, and I'm sure purveyors of others will be waiting in our lobby soon. But not one of the items we tested worked. At all. There's no ignoring the laws of physics, people. Your vehicle already burns over 99 percent of the fuel you pay for. Less than 1 percent is squandered as partially burned hydrocarbons and carbon monoxide before the exhaust hits the catalytic converter for the last laundering. Even if one of these miracle gadgets could make the combustion process 100 percent complete, the improvement in mileage resulting would be 1 percent. Any device that claims quantum-level increases needs to be examined with considerable skepticism.

We say caveat emptor (let the buyer beware). But there are plenty of people out there who say: "There's one born every minute." Prediction: Within a few weeks after the appearance of this article, there will be gas-saving gadgets on the market that tout themselves as "Featured in Popular Mechanics." Someone will buy them. Probably not you.

WHERE ARE THE PICS.....

Re: Water Injection Installed

LOL @ you guys.

Ok, the pissing on the air filter and red bull idea gets applauds. :clapping:

Re: Water Injection Installed

Ok Guys I am New Here..I own a company in Canada & we have just finished a hydrogen unit..I also own a H2 & am looking forward to testing our unit on my rig...I have just returned from flordia where i spent a few days learning how to reprogram the E.C.M ..The problem is that when we use the hydrogen
the computor thinks the rig is running lean..and dumps more fuel in .So we have to reprogram the E.C.M. to accept the hydrogen...Our first unit we did was a ford explorer was getting 12 mpg on the highway...After reprograming the ecm & adding the hydrogen we topped out at a amazing 32mpg hwy.We are takeing my rig to flordia first part of august to superchip customing tuning to run some dyno testing on the ecm & hydrogen...Keep you posted if we even get close to the results of the explorer we will have a winner

Re: Water Injection Installed

Read Yettis comments above. If water injection and other stuff worked to improve MPG, all the fleets would be using it. The manufacturers would boost their CAFE (look it up) ratings.

There seems to be some confusion, so here is the skinny......

The only thing water really does is cool the intake mixture, so more air/gas can get into cylinder. It also makes things burn cooler, like someone already mentioned in this thread, so you may need it with some turbos/supers for this reason. Nothing to do with gas mileage. Because of what I said above, it can actually decrease your mileage, but can (in some cases) give you more power since you are burning more gas (not less).
