will this be effective for track runs in fl humid heat air when the intercooler gets heat soaked?

i'm thinking of buying an aquamist system to spray the intercooler down, think it's worthwhile?

Did you know you can make your own? You can buy a small roll of copper tubing (probably 1/4") and a small hand bender for it. Grab a nitrous purge switch (can be found on ebay as low as $5 or new for about $75) and the brass connectors for the bottom. Get a CO2 bottle (like the kind you put on a paintball gun) and mount it upside down in the engine compartment. Hook it all together with a switch inside and you're good. It is suggested that you spray paint the copper tubing silver to match the intercooler and you may have to test a piece of tubing to figure out what sized holes work the best.

What you do is spray it for a few seconds, between runs to keep the intercooler from getting heatsoaked. A CO2 setup is good for about -100 degrees fahrenheit (if I remember correctly.) Much better than water and fairly cheap to make!

What samel is talking about above is a CO2 Sprayer.. not water. The CO2 will work better, but be more expensive to use(bottle refill).

They DO WORK, the warmer it is outside, the better it will work.
You also don't have to have the bottle mounted in the engine bay... it can be routed to use in the car.

A home built system Total cost should be about $90($15 + $75 for purge valve) If you get the valve used, the system could be as cheap as $20. 8)

When your ready to go, just push the button for a second to Ice the FMIC and your ready to race.

Or you can just buy one made here....

yea, i figured i can make my own..and its probably the better choice, aquamist is kinda pricey.

i have a co2 tank....from a paintball gun, but its a hassle to have them filled, water is much easier. and its usually in the high 80's low 90's here, and really really humid. so water will probably work fine, co2 would be better tho, but it's just the fillups.

if i make my own..what kind of pump thing can i use? to pump the water?

 

[SpitterGuy]

If i plan to cool my intercooler, I'm going to use c02. I also paintball as a sport and since I bought a gun a Dick's, I get free refills, plus no hassels cause I go in there alot. Ever felt compressed C02? It's not fun. Stays much cooler than water, which car wise, is great.

I have heard of guys using windshield washer pumps to spray them with water. Maybe there's another stronger pump?

Anyone think about an aquarium pump? I'm still thinking about a way to do it, but since the output opening on most is almost 1/2" dia., attaching a 1/4" dia tube would increase the pressure.

 

[AWD_ENVY]

You'll want a pump that can provide a higher pressure than awaser pump or Aquarium pump could provide.

I'm guessing that it would still work, but not that effecently. But then again... it's CHEAP :lol:

 

[Grunge]

Next suggestion would be to check out the pumps aquamist uses and find something similar.

Greddy makes a WaterSprayer kit as well.... I think it's around $200 for the whole thing.

Here's some intresting reading on the subject though.

This CO2 bottle is pretty big, but you could mount it in the back seat, although with it weighing 25 lbs, it probably isn't worth it.

This is probably a better size...

Is a 20oz CO2 bottle enough, or would it need to be bigger?

The bottle size depends on how much use want to use it.
I would say 20oz should be enough for 1-2 continueus minuets. That should be enought for a few 10second freezing sessions.

It will work better than watter, but as stated above, it's not something you would have ample of like water.

I thi nk the co2 would also be safer, you dont want water on the track when your launching etc.

 

[insert clever sn here]

good point...

Would it also be more efficient to also spray it while moving...like during the run? Just wondering.

Wouldn't most of it vaporize when it hit the IC anyway?

Yes, but co2 is very, very cold. It would cool a lot better then water and not leave liquid on the track.

 

[SpitterGuy]

You would have to put the sprayer fairly close to the IC.I can hold my finger a couple inches from a C02 bottle and i'll still get freezer burn.

yes, you will put it 1/4 inch away.

Me friend has the NX Nitrous Cooler. It almost touches the intercooler.
