Does anybody know much about this? I know it acts as a kind of intercooler. I can buy a kit for $300 and i have been told it will drasticly reduce knock and Gain me about 30 hp. Are there any disadvantages and will it really produce 30 extra ponies? any help would be appreciated.

water injection? umm how is the water gonna help at all a cooler intake charge i get that much but is it really good to run water through your engine? or does it act as a compression adder as well?

im not exactly sure but you are able to run a water and alcohal mix or just water if you want. im not exactly sure how it works. do you have a switch hooked up for wide open throttle or somthing? im just starting to look into it.

Ive heard before there are "benefits" but I'm not sure if 30hp is realistic. It may help clean the carbon from the pistons and combustion chamber but too much will end up in the oil, BAD!! In general, when it is humid out the water is displacing the amount of air the motor can take in naturally, so I would think adding more would be bad except that you are injecting with the air/fuel charge that is already coming into the intake. An ideal aircharge is very low humidity , high barometric pressure, and COLD air.The alcohol will definitly make a difference in cooling the air charge, but how much do you put in and when do you activate it? I would do some more research before getting too crazy with it, I would rather inject NOS and get a real 50hp.

Ok...I've heard about this on another forum too...There's also an Ntercooler that uses nitrous to do the same thing. You already need an intercooler for it to work...It just enhances the intercooler with either nitrous or cooled air *get this...The air is kept in a nitrous-like bottle, so the ricers will still think ya gots nawwwwwwwwwws on yer car*
That's my .02 on the matter...May be somethin entirely different, but it sounded like the same thing to me...

you dont need an intercooler for this setup. All it does is sprays atomized h20 into the intake. i just dont know how it works and if you use exhaust pressure to activate it or if you have a W.O.T. switch. thanks for the info Ls454. it will take some time before i know whats up with it.

it could possibly be a compression booster i suppose water doesn't compress as easily as air jumping up the compression making more power....jsut think about it though would you spray water into an engine?

well, its not like its a stream of water, its a real fine mist.

It's more of a safety measure than a performance upgrade. Sport Compact Car has one on their 300ZX TT, and I believe the EVO's have it to.

Yeah, saftey against detonation.

its mainly used to prevent detonation. usually its injected with a nozzle and it has a pump to pressureize the system. its not worth the money.

From what i understand, it would actually advance my timing and reduce knock retard. is that true?

yeah you'd have less knock at stock timing, so the knock sensor wouldn't retard the timing.

think of a few things though:

rust, rust and rust.

these cats know plenty about injecting water into their engines. they run good times and get 300+ hp from 2.0 liter four bangers with it.

aquamist is the main company that sells water injection systems afaik.

Thats the kit that i have been looking at by aquamist.

So basically don't get it if you're looking for a "performance hopup" it's just a precautionary item, and if you don't need it then why get it.
