I wouldn't do that at all probably alot of trouble for little gain. Look into getting a C02 intercooler sprayer. CO2 is much much colder than water at outside temp. and will probably cover alot more surface area. Just search intercooler sprayer. Heres a pic

i did it, i went to the junk yard and just used one winshield sprayers and it did not do anything, but make a puddle in front of my tire to burn out in. i tried freezing half the tank then filling it, nothing but a cold puddle. I have even heard that the CO2 sprayers suck on our stock intercoolers. So, to answer your question, nothing (or nothing cheap) will cool down our intercoolers in hot weather. I hope this saves you time/effort/money.

I live in the Phoenix area and the heat around here gets brutal ,
so being broke and all I rigged an intercooler sprayer out of my windshield washer line .
All I did was unplug the line that went to the nozles and routed the line down to the intercooler , I used a nozle I found at home depot that has an adjustable mist pointed it where liked it.
I think its better than nothing in this Arizona heat , I also removed my wipers for obvious reasons, mine leaks alittle bit but not terrible plus with the nozzle I have I can switch it off so it wont drip.

Oh yeah , the co2 sprayers from what Ive read work great on small intercoolers , I think thats what they are for originaly.
I read an article in one of my mags where they installed an co2 sprayer on a buick grand national that had it small stock intercooler on it and they gained like 20 hp.

The latent heat of water is very high, so a lot of gain can be had in getting water to vaporize off your intercooler. And, once built, they are free to keep stocked up, unlike a CO2 sprayer.

The problem, however, is that you're using windshield-washer jets and windshield-washer pressure. That just squirts a stream of water, which won't vaporize off your intercooler ... it will simply wash it and create puddles or worse, such as wet one front tire and not the other. The only cooling that you're getting is related to the specific heat of water, which is not very high.

You need to use a misting nozzle for the sprayer, which will also require relatively high pressure, such as 80 psi or more. Can't be done using the pumps for the windshield. You need something like a ShurFlo pump from Northern Tool.

I have a water sprayer on my Probe and it seems to help, altho the Probe's i/c is a front mount. I used a windshield washer system (reservoir and pump) off a junker along with plant misting nozzles from Home Depot. It also helps to use 50% water/50% alcohol for better evaporation/cooling. I also hardwired the cooling fan so it's pulling air thru the i/c all the time, which helps while sitting at stoplights or in the staging lane.

-There was a page at vfaq.com on how to do this, use the rear washer bottle, run a drip irrigation pvc hose from back to the front of the IC, punch a small hole in front of the IC's plastic air dam and feed the hose through, use a 180 degree spray pattern drip irrigation sprayer that spray fine mist ($.10), since the IC is lower than the washer reservor, gravity will drain the whole bottle once you hit the switch even the pump has stop, so you need to install a small one way air valve (aquarium) so when the line is no pressurize, water will drain back into the bottle, I use washer fluid and 1/2 bottle of rubbing alcohol, this project can be done for under $10.

Thats why I used the front bottle, it is a lot lower then the rear one, it is infact lower then the IC, atleast the motor itself it. Works pretty god, got some kinks to work out though

-Yeah, but every time you activate the pump, the wipers move, the rear pump can be activated without moving the wiper.

Actually I rewired the whole system so that I can turn it on with a switch inside the car. It is next to the shifter so it is really easy to get at, I can also leave it on for as long as I need. It isnt hard at all

use co2 system. this is the easiest way to cool it down. The next thing to do is one get a bigger cooler or two make a box and fill it with dry ice and ethylene glycol (antifreeze) with 20% water mixture. (the only prob with this is that you cant use the intercooler unless this liquid is present) a water spray is illegal at race tracks so you cant use water for racing.

PS when using co2 you must isolate the air intake or else the air will be contaminated with co2

Ooookay, that's about deep enough.
