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:

Come on now John...............you have to be kidding me. Cant wait to see how it works for you.

No kidding. Can't wait to see this train wreck. I predict a truckload of fail.:clapping:

Johndjmix1,

Where's the picture of the install?!

I'm starting to feel a chuckle coming on!

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.

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.

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:

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.
