Spraying intercooler...

[Billdogg]

I don't know if anybody does this, but if you sprayed your intercooler with cool water, wouldn't that help cool down the air going into your engine? If I'm right, you could make a cool system by using your windshield washer fluid system. Fill it with water and aim the sprayers at the intercooler. Just an idea I had. If I'm out of my mind, please tell me why.

They dont usually like you spraying water and making puddles at the starting line of the track. Otherwise, It would help if you could spray a liquid with a high evaporation rate, like denatured alky (flammable though) or you could try packing the intercooler with dry ice in a custom box around it.

Your idea is the same as a liquid intercooler, and yes they make them but they are expensive. They are designed to have water transfer the heat away, unlike ours which are designed to have airflow act as the heat exchange agent.

Hope this helps,

might work. i know NX makes a ntrous kit like this that uses a bar to spray a wide area of the intercooler w/nitrous. at higher speeds the water would probably just spray through the intercooler and have little effect IMO. it would help keep air temps down at the line where there is not much air flow through the intercooler. although im not sure how the other guys at the track would like a big wet spot on the starting line

haha, bob. great minds think alike i guess, LOL

Ok, didn' think about the whole track thing. What about on the street or once you're already taken off. Would there be much difference?

Neat idea if you ask me.

There has been some discussion off and on in the past about this.

I actually tried this in about '96. I used two rows of about 4 sprayers each mounted to the inside of my 20 row IC's shroud. The nozzles were "misters" that are used in hot/arid areas to humidify the air and, hence, cool it. I triggered it with a boost switch and also a manual override switch. My thinking was that it would be most valuable after doing the burnout and before pulling up to the line. However... I didn't take into account the fact that the nozzles were mounted so low they would siphon and drip onto the track! I got pulled from the line twice in a row so I drained it so I could at least race that day. Hmmm... I even remember the track official wondering why it smelled like alcohol!

Shortly thereafter, the "custom" wiring job that I did for that sytem shorted out... then the car got put away for about 6 years do to a variety of reasons.

Anyway, with an inline solenoid to prevent the dripping probs, I'm thinking it would have helped at least a little, but can't honestly tell you!

Spraying intercooler

I've seen spray cans of "Freeze" that chill to a -62 degrees that is used by computer techs for cleaning and troubleshooting pc boards, creative and find a way to mount the can where it would get a good spray to the i/c, then a way to open the nozzle for spraying. Doubt you could get much "cooler" than that!

I was thinking about using co2 and putting on solenoids to spray the ic. Its very cold, cheap, legal, and should be simple to hook up. Maybe nos solenoids, nozzles pointing at ic, 5 lb tank up front, button activated or hobb switch activated, should lower the temps a little, just gotta make sure the co2 goes across the ic, and not over or under. Would a very cold shot on the ic harm the metal? I seen Bill Foutris cool his ic with nitrous once, same principle, only cheaper. Opinions?

also, brake and parts cleaner ($1.79 a can at Discount) cleans dirt off effectively but also vaporizes almost immediatly after contact. it gets very cold too. it would probably evaporate off the track before you could leave the line. at $1.79 a can its worth a try

I thought of doing the same thing, wiper sprayers and all! I was worried about unequal cooling. This may cause cracking in the intercooler. If the intercooler did not crack, then it would help with heat transfer.

I just posted a similar question in the Hot Air area. My car is an 85 so there is no intercooler. But my thought was to use a fogger type nitrous nozzle to spray the turbo and intake with CO2. Not exactly sure what CO2 evaporates at but I know that it is very cold when it does.

In the case of an 86/87 setup you would just mist the intercooler, in an 84/85 I was thinking you could mist the turbo, intake and the piping after the MAF. Has anyone here tried something like this. My main concern would be uneven cooling and developing a wide enough spray pattern

If you shoot nos or something in the intercooler and you have a open filter would it suck it in the filter and blow the motor up or something. I have a nos kit and was thinking of trying it but dont want to take a chance on the filter pulling it in .

I've been thinking about this for a while. Would the pressure from the windshild wipper fluid "pump" be enough to "mist" the IC for about 3-5 seconds?

Wooohooo! Now I have something to do this weekend.

Oh wait, forgot the washer fluid "Pump" isn't working.
