1st. the water to air intercooler uses a closed loop of water to cool the incoming charge of air to throttle body. the warmed water, through heat transfer, is routed to go through a radiator of sorts, to heat exchange the other way , then the cooled water goes back to the other one- internal, cycle.
water injection- this is where water or water/alcohol mix is injected right into the fuel/air mixture in order to be in the combustion chamber.
$200 is quite low. im not familiar with a system that cheap. aquamist has one, but its gonna be in the $500+ range. a couple of my buddies with grand nationals have water and water/alcohol injection. they can run a higher boost than the normal ones due to the water slowing down the flame front and thus reducing detonation possibilities. this is the primary function- the cooling affect is a side benenfit.
the mystery at this point is the tuning. you will need a way (computer i would guess) to regulate the exact amount of water to be injected.
you would also want to do this at a dyno probably to make sure you are helping instead of hurting.
i like the idea, and so does Mike at Active. i discussed this with him a few months ago and he is positive about it. they just have a lot going on right now and designing a water injection hasnt even made it to their drawing board right now. (least of priorities). trust me, if they had one,,, i would have to have it. with the research they do, i would know that it would enhance my performance.
hope this helps
ps,, i'm pretty sure im taking my car down for a stage 2 + upgrade. i think i want to shoot for the 10's now! in my grocery getting/daily driver.
: Isn't this more or less the same idea as an air/water intercooler or aftercooler?
