IC cooling

[jaktheripper]

Ok, I've seen intercooler sprayers and whatnot, but I was wondering something. I keep a minature fire extinguisher in the back of my car just in case worse comes to worst, and I was wondering would it be safe and/or benifitial to spray my intercooler down with it to help it cool down between runs at the track? I still have the side mount, and I've heard alot about heat soak and letting them cool for some time, so would this aid in the process without harming it? Thanks.

If you're that worried about it, just bring a little spray bottle and mist it with water after the run. Don't unload the extinguisher on it. The thing will look like a marshmallow after you're done with it.

Fire extinguishers generally are designed for one or more classes. Commonly available are A (water), BC (carbon dioxide), ABC (dry powder), and ABCD (halon).

A fire extinguisher may emit a solid, liquid, or gaseous chemical.

Water is the most common chemical for class A fires and is quite effective as one would imagine. Water works to extinguish a fire by simply cooling it below the ignition point. However, it will merely exasperate other fire classes. For instance, water sprayed over burning liquid petroleum merely spreads the flames around.

For classes B and C, a dry powder is used. This provides a blanket which blocks the fuel from oxidising.

Carbon dioxide also works on classes B and C and works by displacing the less dense oxygen. This can be problematic in enclosed occupied spaces as we need oxygen too!

Halon is the universal extinguisher. It will extinguish any type of fire and is highly effective. It works by breaking the chemical reaction of the fire. Halon is a chlorofluorocarbon and is being phased out for more environmentally-friendly alternatives. Halon fire extinguishers may cost upwards of $800 due to production and import restrictions.

If you are just trying to lower the temps I would use a can of compressed air. Wearing a glove, turn it upside down and spray the piss out of your intercooler. Repeat until can is gone and open another. $2 a can and all that is in it is cold air.

that works

And, in part, by smothering. You need to get the fuel below the flame point, not ignition.

I saw this stuff on horsepower TV once.. it was like called CHIL or something. It was this spray stuff that would put fire out and cool down whatever you sprayed it on real quick. The stuff was real neat. He lit an oil soaked rag on fire and sprayed it with the stuff to extinguish it. After he sprayed the stuff on, the rag would not ignite again.

I don't even know what i'm talking about. I barely remember it.
