Water Injection Installed
 

I made a makeshift water injection system for my H2 today. Cost me about $10. Expecting gains of 5-8 MPG.

Did the same on my mustang when I was in high school, worked great....gained BIG mpg's. My teacher was seeing gains of over 20 MPG using water injection.

For those that dont know, water injection is a PROVEN way to increase milage, and power (And reduce knock and let you run more boost if you have a supercharger). Not a mystery, not somthing that is a gamble, not some new age tech thing that costs $5,000..........its old school and it works, period.

Im under the asumption that the computer will raise IGN advance and lean the mixture (Better milage). If not, someone let me know and Ill have to pick up that device that allows you to connect the laptop to do it.

Please post the before and after dyno charts along with the fuel/air logging with you water injection. BSFC would also be nice to corroborate your thesis, as would be EGT. I do not doubt the power increase, as the injection acts as a "chemical intercooler". It is the MPG increase I suspect.

FWIW, Wikipedia is a editable source page and not to be used as an end all for hard information. The info is only as good as the lasy guy(s) who posted/corrected the info.

Also, for a non-boost charged engine, this idea will not access any more HP than stock. The added "octane" and cooling of the combustion chamber isn't needed in natural asperation.

And, it isn't water. Its either alcohol or methanol. Either of which is a corrosive to a stock engine.

I piss on my air filter and have seen gains of around 35% you should try it....It really works!!:notallthere: :OWNED:

Johndjmix1,

Where's the picture of the install?!

I'm starting to feel a chuckle coming on!

Re: Water Injection Installed
 

Cant wait to hear your results. Never heard of water injection giving better mpg, hydrogen yes, but water no.. so we'll see.

Re: Water Injection Installed
 

Running the water injection allows you to run more IGN advance, and a leaner mixture....hence saving fuel. Its not really any "mystery"...thats a fact, I would like to see someone prove that wrong.

Cant beleave you guys havent heard of this....its common knowledge....been used for YEARS. I remember my 6th grade teacher did it on his mustang.

Ill post some pics tommorow if I remember, but basicly it involves this:

Get a strong container (I used a small gas can). run a line from manifold vac into the top of the can, just into the can *NOT* in the water. Drill a hole and feed the line in, but make it fit tightly as the can needs to be air tight.

Drill another hole in the top and run a line into the can to an aquairum air stone siting in the water. Have this line come out the top of the can and just cut it a few inchs over the top. I have 3 of these lines set up with 3 air stones.

Fill the can about 1/2 way with Water.

When you start the motor it will suck on the inside of the can, and you will see the can "suck in" a bit. The only way the vac can get air is through the air stone, which creastes bubbling water in the can. This bubbling creates a mist which then gets sucked into the motor from the vac line.

After a week im seeing about 3 mpg better than without it....not as good as I expected, but still....

Im trying to think up a better way to get a fine mist into the motor. Im thinking of buying a cool air humidifyer and taking it apart to see how it works.

The hydrogen generators are interesting, but it would seem it would take more power to make the hydrogen then is saved by it. Some say it works amazing and others say its a hoax Anyone tried this?

Guys, no laughing here....(. Just trying to figure out ways, like all of us, to save some cash at the pumps! Im just experimenting myself, but hey....I know there is a way to deliver the water right...just got to figure it out.

Re: Water Injection Installed
 

Anyone tryed the hydrogen products? Or do i have to be the guini pig for that too?

Re: Water Injection Installed
 

You can't make an efficient hydrogen refinery from a gasoline engine powered alternator. These systems remind me of perpetual motion claims.

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.

Re: Water Injection Installed
 

I just gained 10mpg for free. I was heading down hill and put my gear into N and BAM 20.5 MPG....:popcorn:

Re: Water Injection Installed
 

Wow. Were your tires deflated? Check out my MPG.:fdance:

Re: Water Injection Installed

Re: Water Injection Installed
 

I think if you mix in some Red Bull with that water it will give you the boost in power you are looking for. :lame:

BTW, Wikipedia is NOT a reliable source for information, it is only as accurate as the editor. No fact checking, cross referencing, or corroboration needed. Boneheads.

Re: Water Injection Installed
 

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:

http://en.wikipedia.org/wiki/Law_of_thermodynamics

Because these snake oil salesmen are breaking #2.

OMG... I am on my ass with that one..LOL

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
 

you too, huh !

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.

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).
