an intercooler question
hey guys,
some dude today told me he can get a good deal on those water jets that blow water onto the intercooler to cool it down a bit. you guys know what Im talking about I am sure. It blows a mist of water onto the intercooler to reduce the intake temps.
whats your take on these products?
thanks
Jared

it should help cool the intake charge due to chemical processes of evaporation.. best if you could put ice in with ice water to cool it down as much as possible. it should cause the differences between driving on a hot day vs a cool evening.

Yeah, it should help a good bit, esp on hot days. But, I am a bit partial to using water techniques to cool/keep from detonation. Take "water injection" for instance. You have your boost set to say 12 or whatever, and say you have to inject water at that boost level or you'll detonate. You go to race a guy, or run at the track or something, and in the middle of the run, your water bottle goes empty.. you then detonate, and **** your **** up. I guess thats a good bit off topic though.
I dont know, it would be good, just dont depend on it to lower intake charges to prevent detonation. At least i wouldnt in fear of the bottle going dry.
Though, ill remind you i dont have any experience in water injection or anything of that matter and am probably ignorant and uneducated. Anyone care to teach my stupid ***? Thanks

Excellent Point. It shouldn't be a dependant thing but like drag'n on the track it chould be helpful also an idea would be for road racing. since naturally you're motor would be runnign quite toasty it might help cool the car that little bit that you need. Like Roy says though not something to depend on .. maybe somethign to give you a little 'edge'

IC water spray are a proven way to lower inlet temps, boosting power and reducing the chance of detonation. If you're interested in IC sprays, read this series of articles from Autospeed. They cover how intercoolers actually work (as opposed to how most people think they work), how to build an effective sprayer and have an awesome intelligent sprayer controller to make it work properly.

Haven't we ALL heard this
Just wanted to toss this in. If you put a bag of ice on the top of the intercooler watch where that ice cold water goes. I did that at an autocross and caught it as it was draining onto the turbo and exhaust manifold. That could probally do some damage.
Also with the sprays it may be a good idea to run distiled water if you have really hard water in your area.

Water injection systems come stock with all new WRXs, so I guess that the Prodrive Team really know their **** when proposing such a solution....
It is actually used to increased the HP output by boosting a bit more, and lowering temps->increasing O2 percentage in the intake charge. I dont think that this system can be effectively used to prevent detonation....

They have IC water sprayers, not water injection.
If the intake temp is lower, not only is is denser (more O2 so more power), it is less likely to detonate. Remember detonation is caused by the air/fuel mixture spontaneously igniting because of it's too hot. So the cooler the entering air is, the further the air/fuel mix will be from it's ignition temp. If you suppress detonation, you can run more boost and/or ignition advance.

2) Yes, the final result is the same but the purpose of this mod by the Prodrive Team was not to prevent detonation. They wanted to up the boost in a safe way, and provide as much reliability as possible. The water injection system is an on/off system in WRXs, and you can turn it on/off whenever you like, without fear that the engine will detonate
