I just checked out the link to their site but I still dont get what its all about? They want you to spray water into the air intake? WTF? I thought that was a big no no. Could someone please clarify for me because I am confused and the site gives no real info that I could find.

That water is sprayed in before ur turbo and is vaporized to cool the air charge greatly.

Basicly WI brings down your intake temps which means more power, and other cool stuff. It dosnt spray like a faucet, but sprays a mist. At least thats my understanding of it.

No, the water is sprayed after the turbo. It would just heat it up again if it was sprayed before the turbo.



it reduces charge air temps, which in turn reduces detonation. People are running higher-then-average boost levels on pump gas due to this.



I've heard there is a "steam cleaning" effect as well, but i think it is prolly BS, ive opened up a motor that ran WI and it was just as dirty as anything else..

actually dragon says that the steam cleaning effect is true on the water injected engines that he has openned.



we had a discussion about it, when goodfellas and his dad stopped by my house

it will keep the carbon buildup from being as bad..i've seen a few spotless engines torn down that were using WI

If you do a search of the internet, you can find how this was used back in WW2 for aircraft engines. That is when this all began. Even how it works. Get to it!

You should have a look on www.ausrotary.com

Look for posts by Bill Shurvington. He is top dog for thermal dynamics and WI. He knows all the info on injecting at the scroll and injecting after the intercooler.

I was under the inpression that post intercooler spray was the prefered method for anti detonation.

I watched a fd run at 1.3bar of boost on a T04e turbo with stock seals and its still good to this day. He ran a WI system that was activated by a boost sensor which kicks the WI at 10 psi.

Coolingmist.com has a WI product for N/A engines.



Of what use would it be for an N/A? Would it make any difference at all?

Water Injection is occasionally used on high compression N/A engines so that they can be ran on something other than race gas. I think I heard something about old school hotrod V8's among other examples......



Kind of a "lets get this historic/valuable engine to run on street gas without tearing it down and replacing the pistons, which would wreck its character/collectability/value" type of thing.
