I'm looking for the system that sprays water on the intercooler
Anyone know anything about it, is that something to consider instead of getting a larger intercooler?(short on cash). Any comments on it would help.

Good write-up...but if you read carefully
There was no temp change. That is the problem with intercooler spray systems. If your intercooler is getting hot, they do what they are supposed to: cool from that temperature back to ambient. Really, at best (and I like this system) all you accomplish is to *guarantee* the nominal efficiency of the intercooler (7x% at stock levels and worse at higher boost).
A more effective means of accomplishing charge cooling (what you really want to do) is to use either an internal, water injection system such as aquamist, or both water spray and injection.
Injection literally cools the intake charge far beyond ANY intercooler (latent heat), and the vapor water (and typically a small amount of alcohol) *acts* as extra octane (knock resistance). (AND, keeps our pesky carbon buildup from happening!)
This lets you run more boost without having to find race gas.

Yes but who is going to rebuild your motor when the internal spayer breaks and floods the car
with water. It is not a pretty sight. Water is also not a very good thing since it does take away space from 02. The best thing to do is use a setup that cools the FMIC or the IC pipes using co2 or your A/C.

Way old school...
Aquamist is OEM for several brands, it is more than safe. It has a processor that looks at system status and cuts off flow if there are problems. The orifice is far too small to allow what you are talking about, even if *everything* fails.
Yes, a person could damage the engine with 'hydrolock,' but that was only theory with the very old engine vacuum passive systems and the old windshield wiper pressurized systems. But really all I've seen even with very crude systems was diluted oil and carbon "farts."

But why not just do it an easier way by using co2 in a tube around the IC pipe or even doing it
using your A/C setup. Just run the A/C and the pipe is cold and making your intake charge very cold.

There's no free lunch. There is also some misinformation in this thread.
Cost/benefit(if any) for water spray on the IC is not good. Check down a couple of threads for NOS spray on the IC. Better, and lots safer than injecting NOS, but still not cheap.
Using a/c to cool charge requires mechanical and thermodynamic efficiencies well over 100% to get a gain. Tough challenge.
If you haven't 'chipped', consider starting there.
My $.02.

But you gain more hp then you lose and when you turn it off the pipe stays cold for a pretty long
time. This is a very good setup for drag racing and autox since you just run the car for a few minutes and then shut it off before you make your run.
