Fabricating some sort of intercooler sprayer

[rocketspeed]

Think it would be worthwhile to fabricate some sort of water intercooler sprayer? Both Mitsubishi and Subaru have employed water sprayers in the past. Seems as though this could be done cheaply and easily.

Sport Compact car converted the washer fluid sprayer on their project Silvia into one, with good results as far as stalling heatsoak goes.

Anyone ever try this, or give it thought?

Be smart use Co2......it'll create a hellava lot better heat transfer than water, and you can use it on the track.

 

[rocketspeed]

Co2 raises cost and complexity, however. I'm thinking this would be one of those projects you could run for literally just a couple of dollars. A small tank for water, a pump, , some rubber hose, a sprayer nozzle, some wires and a toggle switch.

 

[BlkZoomZoom]

Mine was 35$......however it's 5 bux to fill the bottle.

I did play around with just T'ing off the washer sprayer line, then disconnecting the wiper motor,. I didn't like the smell of the burnt washer fluid and people at the track were not happy with me.

 

[rocketspeed]

Price is right at $35. Where do you get the bottle filled? Did you ever post a thread about putting one together?

I wouldn't run it off the washer fluid, don't want to spray that gunk on the intercooler.

I was thinking get a donor washer motor & fluid reservior by scouring the junkyard, mounting it in the bumper or somewhere hidden, run a little rubber tubing to a garden type sprayer nozzle pointing at the intercooler and run a toggle switch through the firewall and mount under the dash.

Would need to drain it in winter around here, though, or the water would freeze. Just thinking out loud.

I'm interested in your homebrew CO2 spray system. You seriously did it for $35? Whats it involve?

 

[mazdaspeedpower]

yes, fill us in. Did you notice an difference in the performance of the car????

 

['Sploder]

maybe a bit of a how to?

I could build a co2 sprayer with instructions this week for about $25, all you need is a 20oz paintball tank, probably 6 feet or so of stainless steel hose (to reach the into the car), some sort of valve to control it, I have one from a drop forward on another paintball gun, and some mounting hardware. Just put a few holes in the area looped over the intercooler maybe with brass spacer things to keep the holes open, eh too much to type out now, I'll make a how to later

i did it for 3 dollars

take the windshield washer hose and put it in front of the intercooler with a mist nozzle i bought at home depot. whenever you need to cool the intercoller just spray with the winshield washer I filled it with water for my test. I didn't seem to notice any difference. Maybe c02 would work better but it is alot more money. I mad this temporary to see what it would do. I returned it back to stock. for 3 dollars to find out not bad.

jred321 - Hey dude thanks!

Yea I did an intercooler sprayer. Very easy. Just read my post and you will see how I did it. One thing I did add was an insect sprayer nozzel from a gun I bought at Home Depot. It was 8 bucks and it makes a nice spray.

I wonder if it would be possible to use the A/C system for cooling? Might be a stupid idea, but if you could route some type of coolant lines around the IC it may help. I understand that the A/C will drain some of the power, but it might create more.

 

[rocketspeed]

Maybe. I'm not really thinking about power gains as much as I am preventing the intercooler from becoming heatsoaked.

 

['Sploder]

so has anyone come up with a dedicated CO2 system yet? i really dont want to run it off my washer fluid because its not just water.

[edit] also what kind of lines/nozzles would be needed for CO2?

 

[SmoothCriminal]

ok I've pretty much got the complete co2 system planned out in my head, but I haven't thought of a way to store it/route the lines yet but here's what you'd need.

some 1/4" stainless steel tubing, about 3 feet or so

some stainless steel hose, high pressure stuff like from a paintball place, not somethin meant for a kitchen sink and some sort of valve, OR something like this http://www.xtremez.com/paintball/pr...C&variation=&aitem=2&mitem=&back=yes&dept=133

a decent sized paintball co2 tank, I'd go with a a 20oz

random plumbing fittings and solder

mount the tank under the glove compartment so you can easily get to the top of the tank to twist the valve and turn it on

run the line all the way into the engine bay to the intercooler

drill small 1/16" holes along the middle of the tube all on one side

bend the metal tubing into a shape something like this and mount it to the intercooler with some zipties

put some sort of cap fitting onto B preferrably soldered on with a torch (use pipe solder)

if your remote doesnt reach A then put 2 ends on an adequate length of steel hose and bridge the gap from the tank to A

thats all you'll need

should endup something like this

- I think they did this with one of the Turbo charged Focus's. I'm not sure if its the present Euro RS, but i definately read somewhere that they took advantage of the AC hoses.

smooth criminal, everything sounds good except the placement of the tank.in a front end collision that thing would be a weapon. Might be a pain in the ass but somewhere like the trunk maybe would be best. as far away as possible at any rate. Maybe rig up some sort of electric bottle opener as well.

 

[SmoothCriminal]

nah theres a relatively small amount of co2, it shouldnt do any real damage in a collision, if anything it might burn the passengers skin being so cold, so just put it in a holster type thing around it, maybe locate it under the passenger seat
