Now that I have your attention, what in the world is this??? www.aquatune.com Any one hear of this and what merit does it hold? All you techno gurus let us know what you think. I might even be so inclined to try it and compare on a dyno just to see if it works.:wink:

I have a Spearco H2O injection on order for my car. Mines more to cool the intake charge under boost. I will have before/after dyno results for those who care. I don't expect much if anything in terms of more power.

I'm really interested in the results and installation Barnaby, make sure you let us in on how it goes.

Why not go with a Vortech aftercooler?

If I'm not mistaken, P-38 Lightning's had water injection to satisfy their combination of super plus turbocharged engines

I would be very interested in real before/after dynos.

One thing I find interesting is that in the "how it works" section they claim to break the H2 and O bond using ultrasonic waves.. later they clain that the hot carbon deposits in the combustion chamber don't mix well with "water" and the carbon disolves.. I thought the water was changed into H and O and was no longer H2O??

It was mainly used in the 70's to fight detonation on the older cars,trying to use the lower octane fuel. As far as making more HP,in a N/A setup,it don't work. Combustion heat creates the pressure,which makes the power. The limiting factor will be the octane level of the fuel.

The water's main purpose is to cool the intake air by vaporazation. On a NA car you might see some gain on hot dry days. On a boosted engine it can work pretty well, cools the air charge that was heated by compression but without the pressure drop caused by an intercooler. A good system would use an intake air temperature sensor to adjust the amount of water spray. An ultrasonic nebulizer makes sure the water vaporizes fully and fast, but in no way breaks hydrogen-oxygen bonds. But carbon in the piston chamber could react with steam to form a mix of hydrogen and carbon monoxide, so it is theoretically possible for a water injection to clean-up carbon deposits. I don't think carbon deposits are much of a problem in modern engines though. Bottom line, you guys with superchargers could see some improvement, not much for the rest of us.

Well Steve, if you haven't noticed by now... I'm weird. I researched all forms of intake cooling and this one peaked my interest more than inter/aftercooling. I know I am limited in it's effectiveness, but it's different and gives me something else to learn.

I turbo'd a 1600cc '76 Dodge Colt way back...the original ricer :smile: I had water injection on it, the main benefit was to cool the intake charge, which could run several hundred degrees under boost and increase potential for detonation... so, without an intercooler...water was the accepted practice back then. I could vary the boost from 10 to 20 lbs (forged 8:1 pistons) and when running at the high end I would use alcohol...anyway, it screamed at 20lbs.
