So, I am cheap, and refuse to spend 300 bucks on something that sprays water, so, after viewing a post on a WRX forum, I decided to build my own intercooler sprayer using mostly parts I had laying around.
This whole project started as a concept/boredom, so the execution is rather crude, but I just wanted to prove the concept before I went around making it fancy.
Parts list:
3/16" PVC tubing
Windshield Washer Pump
1/2 Gallon Milk Jug
Wire, Wire Ties, 1 switch
Irrigation spray nozzles
This cost me 10 bucks for the spray nozzles and the PVC tubing. If I didnt have all the other stuff laying around, it might cost a total of $30.
Procedure:
Remove intercooler cover.
Run PVC tubing along intercooler cover, wire tie in place.
Drill hole in milk jug on the side, somewhere near the bottom.
Install rubber grommet (comes with the pump). Install pump.
Reinstall intercooler cover.
Run tube from intercooler to pump.
Run power and ground wires. Install switch somewhere in cabin.
Drill small hole in tubing. Install irrigation sprayers.
Done.
Pics:
These nozzles can be found in Lowes, in the plumbing section.
I will prob spraypaint the reservoir black to blend it in better, as well as make a better mount for it.
Outcome:
I know it isnt as good as a true intercooler sprayer, but 300 dollars can buy me more performance with methonal injection. I made this to spray the intercooler between runs at the dragstrip. I do not have dyno, nor track times to demonstrate if this even helps. I can tell you that after driving my car hard, I pulled into the driveway and shut off the car. I raised the hood, and put my hand on the intercooler, and nearly burned it. I then closed the hood, sprayed 3 quick squirts, opened the hood again, and could rest my hand on the intercooler, no problems. So it does work somewhat.
Note: I chose to run a complete closed loop system, IE, I ran a line from the pump, to the intercooler, then back into the reservoir. This allowed me to lower the flow rate going through the sprayers, without installing a control valve. Contrary to popular belief, more water does not mean better cooling. The object is to atomize the water, creating more surface area for the heat to come in contact with, and then vaporize the water. When the water vaporizes, it removes heat from surrounding areas.
Enjoy all.
