Intercooler misting?

[sacker00]

Anyone ever hear about this? any info please...

 

[larryd]

you mean water misting? or nitrous?

 

[sacker00]

Water i guess....

y, know, I was thinking of doing this before I bought a Talon. I had been doing research into turbo cars in general, and I came up with an idea to mist water or alcohol onto the intercooler to cool the charge even more. It would use a w/washer pump and tip, and some tubing. It could be switch activated, boost activated or a combination. Or even crazier, you could tie it into one of the fancy aftermarket computers you all have and make it come on depending on ambient temp, temp at the throttle body, boost, timing, throttle position etc.

I thought I had come up with this on my own, but apparently some others have thought of it too. Some with good results, and I may do it too some time.

You want some higher pressure pump (at least 60psi) and nozzle than the stock washer unit. Atomization is the keyword for water/alcohol inj.
There are many water/alcohol injection info out there and has been tried for a long time. All you need to do is search

hey jw, I think that we were talking more about external misting, to cool the outside of the intercooler, thereby cooling the air inside of it. On the theory that water or alcohol could take away more heat than the air. Not alcohol injection internally in the engine, just as a spray over the intercooler fins. For this I think that a good washer pump and the right nozzle would work fine, especially with a short hose. The one from my 94 Pontiac throws ALOT of washer fluid around

in SCC mag their rally focus does this on its radiator... basically its a length of tubing, a 2 liter, a windshield washer nozzle, and a windshield washer pump (or if you dont use your factory windshield nozzles, just run the line to the intercooler mister, and well.. you have a nice stealth switch for it, and a factory bottle to hold the water) its mostly done on rally cars... i guess most street cars or strip cars cant really benefit from it.. if you think about it drag races are (should be) over in less than 14 seconds.. thats not enough time for the intake charge to be heated beyond the intercoolers control.. maybe on a T25 hairdryer the rally cars are basically longer races, in the heat (baja?) and would most likely benefit from this much more than any street or strip car would. If im incorrect in any of this, please correct me as for now, its just speculation on my behalf.. hope it helps!

maybe not much benefit for a drag race type, but I am more of a road course/rally guy myself, so the longer time at higher temps might help me or those like me. Longer races in the summer time in those twisty bits of "Canadian back roads"(tm), should heat it up a fair amount.

when and if I do it, (after a boost guage, and some more mods) I will tell ya all what I find out.

Hello, this is great stuff. You can set up to inject in front of the turbo intake, before & after the IC, spray the turbo externally, and spray your brakes. This is the next mod I am preparing to do. The biggest thing to make sure of in setting this up is that your water injected ATOMIZES.

If I am not mistaken, the JDM evo uses water sprayers on its intercoolers but not sure. I knwo it can help out a lot when racing but has been baned all all tracks on the planet because it puts water down on the track thus causing slickness and therefore crashes and death = not good. Spraying rubbing alcohol instead of water would be prefered because it evaporates faster but it also costs a lot more than water. Hope that helps you out some.

 

[Bohrn]

yea that makes sense about the water on the track. I wouldnt do that for sure,maybe stuff the area around the intercooler with dry ice??

as for misting the turbo, I think that may be a mistake except in all but the most well thought out and engineered examples. Why? The cast parts on the turbo, being so hot they glow, and then spraying them with cold water, I would be scared of cracking from the thermal stresses.

 

[97GSTAT]

You'll can call me cheap, but I just use a squirt bootle right before I line up at teh track. Now this will be replaced with a N-tercooler nitrous system, but it couldn't hurt anything.

 

[larryd]

supposedly at my track its illegal to spray anything on your intercoole, i beleive that goes for nitrous and water.

 

[97GSTAT]

What they see won't hurt them. And my local track is kind of out of the loop. Nitrous should be alright, considering I've seen many cars purge their nitrous onto their radiator.

 

[kilurv8]

I would be worried about bending my fins by spraying nitrous onto my intercooler. The typical bottle pressure for a nitrous bottle is 900 psi (when heated of course) and anything under that much pressure could do some damage so make sure you do it a safe distance from the intercooler.

 

[RockinRoll]

I read about guys injecting water before their turbos and then finding out that the water droplets had more or less sand blasted the blades on their turbo...not cool. If you decide to use water injection then i would advise you inject after the turbo.

NX engineering makes an N-tercooler kit where you can spray NO2 or CO2 directly on the intercooler. They claim it gave a turbocharger civic 52 hp. I wouldn't expect that much, but I'm going to try it one of these days when I have a few extra bucks.

 

[larryd]

kinda expensive though isnt it?? besides if Im gonna get Nx im gonna use it in the engine not on it

 

[dsmtrick]

It sprays directly on the intercooler. Expensive, probably, but it's got my attention.

 

[EuroGSTSpyder]

You are right.:The EVO has water injection on its intercoolers as stock.

I am to buy a EVO IC and put on my Spyder as FMIC and wiol maybe do the water thingy too ..most for fun*S*

 

[larryd]

i wanna know more info on that if u do it

 

[EuroGSTSpyder]

Yes of course I will post info here...I checked already and it pretty much fits right in there in the bumper..Or course you need some minor cuttin too but hey..thats the price right.And as far as the water is concerned..I think I will hookit up to a switch inside the car so I can spray it whenever I feel like I need to...We'll see how it turns out.
