Water injection is nothing new, i think it even comes stock on some WRX'x or Evo's in Japan. Never heard of it for n/a cars though &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'>

i met a guy that would run 31psi wiht his water injection kit......though from what he said having a intercooler would not make it work as well...he had this on a non-intercooled datsun 510.....

I have never read a credible source that thought highly of water injection. Those who has read "Maximum Boost" may remember this quote "A Water injector on a turbo car is a poor-excuse band-aid for not doing the job correctly the first time." &nbsp;Food for thought. But sufice it to say there are probably no setups on this board that could really benifit from water injection even in theory. Oh and ca18guy I am pretty sure that you are mistaken about the water injection on the wrx's. I have seen spray kits for the intercoolers, perhaps that is what you are thinking about. Think about this as well it would only take a very small leak in the injector to destroy your motor. Yet another reason to stay away.

I don't know but I'm pretty sure all the WRC teams run water injection. &nbsp;It is primarly a cooling type system, but during combustion it breaks down into the 2 part Hydrogen and 1 part Oxygen. &nbsp;Both of which would be benifical. &nbsp;SCC did some tests with a Aquamist sysytem that showed sizable gains in power and cooling. (I guess those terms are kind of interchangable) &nbsp; &nbsp;My .02c , not real sure though

If water injection is their primary source of cooling the intake charge, then what are they doing with those silly intercoolers? The article I think you are referring to was the aquamist system on the "Project Rally Focus". This was not a water injection system. Rather it was a intercooler sprayer. Systems used to spray water or no2 on to the intercooler to lower it's surface temp are commonly used in many forms of racing. Including WRC.

This is not the same as water injection, where small ammounts of water are sprayed in to the combustion chamber. To lower combustion temps and prevent detonation. In theory this could work. But the risks associated with it out way any benifits. Proper fuel management and intercooling are more than enough in 99.99999% of all cases. I really doubt that any one here is in that .00001%.

Dude chill out. I know what the hell H20 injection is man. &nbsp;Just because somebody is new doesn't mean they are retarded. &nbsp;What source's for your claims are you refering to.

i think yo may need to chill out, from what i read i didnt seem like he was attacking you at all, just seeing if you got confused or something, everyone get sconfused sometimes, post count has nothing to do with stupidy, thats genes

damn it seems that people's skin just gets thinner and thinner. Now disagreement is considered an insult. Sorry homie welcome to the "real" world. People don't always agree with your, my or anyone else's statements. If you try to make every attempt at discussion in to a personal attack you are in for a rough ride.

Also what is this crap about post count, to be honest I didn't even notice yours. I get corrected all the time. I don't much care by who. Right is right, if you have a point prove it. If you prove your point I will be the first to admit it.

As for the source I quoted. "Maximum Boost" by Corkey Bell, considered by many to be the enthusiast's "bible" on all things turbo. It is a very good read for any one interested in the subject.

Also in he future if you have a concern of a personal nature take it to the PM. Rather than making your self look silly by bickering like a child.

Sure. &nbsp;Exactly what does old maximum boost got to say about it. &nbsp;Sum it up for me. I'm interested.

Sorry. I'm not trying to be a dick, it's just that water -injection has been around forever and so have turbos. &nbsp;I don't know but I think that there are probably credible reasons to running h20 Injection on high tune cars or even cars that have stock internals, or are even subjected to the kind of stress that somebody like us exerts on a car. &nbsp;I don't know if WRC &nbsp;runs it or not. &nbsp; I'm just keeping my options open. &nbsp;Many sides to a story you know?

Well the quote form the book I posted it pretty straight forward. I feel sums Mr. Bell's position well. &nbsp;

No worries... It takes a lot to get me pissed.

Yeah I am aware that water injection is not a new thing. And in theory it sounds like there could be practical applications. I am looking for some credible information on the subject. Like I said everything I have read, frowns upon that method of detonation control.

The one other thing that you mentioned about the water releasing oxygen and hydrogen into the combustion chamber. I am not sure that is the case. As water is a pretty stable element I doubt that the energy is sufficient to break down it's molecular structure with durring combustion. Rather I understood the purpose to be to stabilize and lowering the temp of the mixture to prevent pre ignition combustion.

</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Quote </td></tr><tr><td id="QUOTE">I don't know but I think that there are probably credible reasons to running h20 Injection on high tune cars or even cars that have stock internals, or are even subjected to the kind of stress that somebody like us exerts on a car.
</td></tr></table><span id='postcolor'>

There may well be. However I still want to see some type of proof. Aside from claims made by manufacturers.

As far as reducing stress on internals water injection is only a means of suppressing detention. It has not effect on reducing the compressive or tensile loads on the engine that result from increasing it's power output. So therefore if detention is controlled by means of intercooling and proper fuel management what is the point of water injection. I don't think that any one would really suggest that water injection is a substitute for either proper fuel delivery or intercooling. So my question is what exactly would be the benifit of adding a complicated potential point of falure to my motor?

As I have said before I am not an expert on the subject. I do read a lot on it. But I am not an expert. If any one have good evidence to support waterinjection as a means of detionation control or any other application, I would be grateful.
