Anyone use them still? Remember 4-5 years ago they were all the rage on forums.

In case you don't konw what it is, basically a bar with hole spunched in that sprays a mist of water or even windshield resevoir onto your intercooler, and with a little speed it should cool the intercooler A LOT.

 

Like the sprayer on the Neon SRT4 turbo toys. I don't know of anyone on here who uses one, maybe someone will chime in.

 

Are we talking about meth injection?

 

no a spray bar is meant to cool the intake temps by dropping the temps of the intercooler itself. some people use nitrous to do this and others use co2

 

Not allowed for drag racing.

 

No, something like this: http://www.youtube.com/watch?v=rcW1iVxn8-M

 

same concept. theyre just using water

 

AFAIK all the STis in the USA come stock with an I/C sprayer. Not sure how many people actually use them though.

If you run Nitrous it is very cold, but gets expensive fast. Been a trend for many years (going on 15 years now)

 

Wut? That sounds silly.

Edit: now that I think about it, probably puts liquid on the track...makes sense now, ha

 

there's a couple of cobalts i've seen using the cry02 kits. I've been thinking about it myself.

 

Do this spray water o.to the innercooler. Then have a bitrous bar and spray the ic and freeze the water. But only enough where you can still get good air flow

 

if anything i would just talk to modern perf. seeing as how they're in my hood

 

here's the link if anyone's interested:

They are really not worth it. As long as you have a pretty good sized ic I would just save my money.

 

i would imagine that they'd be worth it specifically if you live in an area that has long periods of hot weather.

 

This won't have any effect on an Heat Exchanger right?

 

don't take my word for it, but i don't believe they would. At least, you would have more benefit from cooling the air after it ran through a heat exchanger. That's why meth injection seems to be more beneficial, among the other performance gains you would get from it.

 

This is stupid. The mist will not cover the intercooler other than just the spot it sprays if your going over 20mph. All the water will do for cooling is bring the intercooler back to ambient temps faster. If you have a massive intercooler like that then your not going to see any difference. The intercooler does not get that hot. A meth Kit is a much better investment and will produce 100x more power than this kit if you tune and dyno both setups.
I came up with this idea about a year ago on my car and tested it to see what would happen. "funny cause i showed one of the guys that works at ModernPerformance my setup before testing it" I simply got 2 vacume Ts, The washer fluid line that feeds the sprayers for your windshield has a break in it by the cowl with two rubber fittings, I put the T in there. "the T has to be at a higher point than your tank" ran some small vacume line down to the intercooler and split it again. I ran the two hoses then to the two tabs that mount the bumper to the crash bar infront of the intercooler. "you have to lay infrontt of the car to see them" This way it aims straight down and pours out a considerable amount of water. It cost me $5 to do and had no wiring. I would just clean my windshield when i wanted to spray the intercooler. There were no gains i saw while datalogging. During summer days with 100+* weather when Iats would climb above 100* i could spray it while pulling away from a light and the iats would come back to cruizing temps faster but that was all. Wouldnt get any cooler than the outside air temperature. This was done with a aftermarket intercooler as well. I could see it helping a stock intercooler cool back down faster if you were making back to back pulls.

I even tried running rubbing alcohol mixed half and half with water. It just helped it cool back down a little faster after coming off from a light during hot days. Didnt make the IATs any cooler than the outside air temp.

 

Or this one

Nitrous Express N-Tercooler System - 00-05 Dodge Neon Turbo Kits and accessories

 

That is what I was referring to. An actual pipe in front of the intercooler that covers most of it with a spray or mist.

Something to look into but I have no data logging yet, need to get a Bluetooth odb2 cable and could data log to my phone. But I'm stock except cai.

 

On an STI the IC is on top of the engine. The design makes it so there is little time from the air getting from the intake to the engine. In a Subaru the air may only travel a few feet, even with a CAI. In a FMIC design the air has a much greater distance to travel. But there's a tradeoff. A FMIC stays cooler that a top mount IC (TMIC). Heat travels up and "heatsoaks" the IC. Spraying a mist on the intercooler will cool the air temps substantially on a TMIC. Not sure how good they work on an FMIC but on a TMIC they do work. You can shave tenths off a quarter mile time just by cooling your IC.

 

waste of money....

 

The problem with your test is that it sounds like you used the windshield washer fluid pump to supply the spray for the I/C. The problem is that the spray will not be atomized and it needs to be in order for the latent heat energy transfer to work properly. That's why meth injection kits use high psi pumps that atomize the spray otherwise it won't work at all (also bc it could hydrolock your engine haha).

An atomized mist of meth would work. Is it worth it? Probably, if you can do it cheap but it's really not THAT big of a difference. Meth injection would be money better spent.
