Homemade IC Spray with pics

[II-Savy]

I think it came out well. I used a universal kit. It came with everything...Reserver, motor, lines, wire, copper sprayers, HUGE metal momentary switch(which I didn't use). Install was easy AFTER I moved it down off the firewall. I forgot about the siphon effect, the water just poured out..lol oops. SO then I moved it down below the airbox, now it's lower and it works great. You can see the black rubber lines on top of the grill with the copper sprayers pointing down.

The second pic is the radio shack black momentary button I used. I think it looks good. What do you guys think?

Shouldve used Co2, much more effective and not that much harder to make.

[II-Savy]

I forgot to mention it was a total of 40 bucks. I had no job at the time and a house and baby to pay for :D

[BlkZoomZoom]

I spent around 35-40$ for mine also.....however it's 5 bucks to fill the bottle.

[II-Savy]

Very cool. That's not too bad at all....

You saying the sprayer was also only 35/40 bucks? What did you install?

[YuYuRena]

u guys should maybe write a how-to. let's not keep the secret all to your self now ;). But good job dude.

[KzA]

yea man..i really wann akno how you did that for 40 bucks..

[jaymode]

do you have to hold the button down? Just wondering if it would be better to have it spray the whole time you are racing like in a 1/4 mi?

[lamp3]

yah, a how-to would kick Ars. Notice a difference with it?

[BlkZoomZoom]

I just used a 20 0z. paintball gun tank,
made a valve work for a water/garden hose,
and ran steel line in front of the intercooler with 12 slits in it,
I had to play with the slit design to make it work and spray right though.....

Performance???? Ha..... 15.0's at 8psi, next run I used the Co2 sprayer at 8psi and ran 14.6's w/ virtually the same 60' time.

Beat that for 40bucks!!!

[II-Savy]

YuYuRena - Yea maybe I will write a how-to....possibly tomorrow, I may have time after I wax her with some Mcguires(sp)

KzA - I want to napa and asked for a universal kit, it's part number 66-01. Big blue box. I think it was 43 plus tax and with my AAA card I got 10% off. The radio shack button was about $1.90.

jaymode - I do have to hold the button down. I went back and forth about that and I decided monmentary was the way to go. That can be changed easy.

lamp3 - I haven't done a real good test, it's prolly marginal at best. It's just for when you really snot on the car.....I will spray it and the IC SHOULD be cooler and be closer to when you just start out driving.

[II-Savy]

Yea ... I need to mess with my sprayers, they are OK. I tried to aim one high and one low to cover the whole IC. I have done a small amount of looking for nice brass sprayers...nothing found yet.

[Ryan]

sounds awesome guys wish i would get my car back so i could continue the modding lol.. geezus.. drivin me crazy

[lamp3]

dude don;t snot on the car, what'd it ever do to you? ;) On the same note caught my dog taking a piss on one of my wheels the other day....bout drop kicked him.

[II-Savy]

LOL :D , Yea I'm nice to it. Unless it's late and I'm coming home from soccer late. Back roads around here are sick. I haven't sneezed inside of it yet.:D

[jonnydoe48]

paintball tank is exactly how i was thinking to go.

[monkeymsp]

It funny after I read the specs on the WRX the other day I had the same idea. Glad someone is trying it. The only concern I had was the water vapor getting sucked into the intake. So I had decided that I would wait for that upgrade until after the CAI. Congrats guys and keep us up to date on how its working and how long the H20 lasts for :)

[Bloodfeud]

Wanna go really crazy? Buy a nitrous kit, and use it for CO2 instead. Costs quite a bit more, but I bet you would get wicked coverage. Also you'd have a larger bottle, and the ability to put in a contact switch that only engaged the sprayer at full throttle.

Hot Damn. I think I'll just do that.

Thanks for the stellar idea black.

Justin

P.S.: Be very careful where you put that bottle, however big it is. If you (god forbid) get into an accident, if that tank valve gets broken you have a rocket on your hands (they go through cars, people, even brick walls if they are big enough).

[BlkZoomZoom]

If you sprayed nitrous in front of the intercooler you would get the cooling affect through the intercooler plus the intake is practically right behind the intercooler so you would also get a big jump in power !!!!


No I don't recomend it........

[II-Savy]

only engaged the sprayer at full throttle.

Someone posted a site about how this wasn't the best time to cool the IC. It think it would have to spray BEFORE you hit WOT....that way you cool air AS your hitting WOT...

Good Point!!!!!

Don't try to use the Co2 bottle with regular vacuum hose!! they pressurize the bottle to 3000psi (so they tell me)
I tried it a it froze moisture in the line and blew it in half!!!
You don't want -54*F blowing in your face!!

[Bloodfeud]

Re-read my post... CO2 instead of NO2.. the hardware is all the same. Outside of the intake, the two gases would be equally as effective to cool something, definitely would affect your performance if you ingested NO2 into the intake. The results of which could be very bad. I plan on moving to a cold air intake mounted in the wheel well, so I wouldn't have to worry about sucking CO2 into the intake and robbing myself of O2 either.

[lamp3]

I'd love to see a few more pics of your water spray install, going to be doing this myself soon.

[II-Savy]

Is there anything specific you want to see? Wireing? Spray bottle install?

[Jason94Cobra]

I wonder if a window switch would work... of course you could just switch out the momentary switch for a regular one so it wouldn't run all the time...

Have it set to start spraying about 1,500 rpms and then it should spray before boost and stay spraying the whole time you're running.

Of course a window switch would raise the cost of said kit to about $100. Of course I hadn't thought of the fact they might not make a 1,500 rpm pill for the switch... hmmm

[II-Savy]

There was a web site around here where a guy did a huge expieriment on way to auto squirt. He ended up making a computer control box that monitered several things.

The way your purposing I think would empty the bottle way too fast.

I used a small black Radio Shack momentary button that hides nice near the dimmer. It works nice.

[Jason94Cobra]

I did some more checking on the window switch and found that it would cost about $80 for the window switch because they don't make a pill under 3,000 RPM and I would think you would want to be spraying starting about 1,200-1,500 rpms and the only way to do that is with an add on module that costs $20, but I guess that is about the same as a pill package.

I was saying to add a on/off switch to the window module so that you would only be using the sprayer while actually making a run or racing someone.

I may have to investigate this further...

[II-Savy]

Dude here is the link, someone has done the research for you:

[505zoom]

Nice job man, looks good(thumb). I would just stick with the manual spray button. Having the ability to fog the IC when someone is revving on you at a light is enough reason by itself:D.

I think most tracks do not allow water IC spray, it contaminates the surface. I know for sure that you can't use the water spray at most auto-X events. The No2, Co2 I am not sure about, I wouldn't think there would be a problem since it is not a liquid that is getting on the track.

[ICEMAN.2]

Keep in mind that a CO2 bottle are a potentiel danger for you... I m a proffesionnal paintball player , and i m used with CO2 and NO2 tank (nitrogen) because my gun s are equipped with that kind of stuff and i can said that , it s a potential danger if you got contact and broke thoses things... I can t travel by plane a full bottle in my luggage because airplane company consider that my bottle of NO2 are a bomb , so you can imagine wath they can do if they break and get off ...

just my 2 cents :rolleyes:

[nocar]

u notice any gains?

[splitvizion]

i would think that the bottlle is dangerous at the high altitude but not that dangerous at groung level. Then again i know nothing about CO2 or NO2. P>E>A>C>E HA HA LOL

[silverturbozoom]

Hey guys what if i hooked up a Purge kit to the front of the IC and have the purge just release C02 on it?

[SmoothCriminal]

im not sure what a purge kit is, but unless its something meant to administer a liquid under exceedingly high pressures that changes phase to a gas at ambient temps, it won't handle co2.

[All Boost]

matt7184- Has a good point with the problems that CO2 absorbing heat I think. I was just about to go with CO2, but there should be nozzles out there that give you a crazy mist that will end up working better. Plus it works well for the STI so why bother filling a CO2 bottle. my 2 beans

['Sploder]

I can see the point of water absorbing a lot of heat (due to the fact that its liquid so it will absorb energy to reach bp, convert to gas, and coninue to heat up) but CO2 is freakin cold.

[jersey_emt]

I'm eventually going to rig a CO2 sprayer using a paintball tank.

FYI - Any bottled gas is potentially dangerous. The air is highly compressed...if the valve breaks off, all of the gas will expand and exit VERY quickly, turning the bottle into an uncontrolled rocket. It will be moving so fast that it will break through just about anything....concrete/brick walls, cars, people....

I use compressed medical oxygen at work, and in EMT school we learned about the dangers of bottled gas.

[BlkZoomZoom]

Mat7184- The reason Co2 is so much better and effective at cooling the intercooler is simple.......the higher the heat difference between two objects in contact, the better the heat transfer.
For ex. water at room temp. 70*F, Your intercooler after beating the sh*t out of your car 200-300*f.
At best your heat coeff. is 130-230*F......

The enter Co2, -54*F (I believe, might be *C), then your intercooler 200-300*.
At worst your heat coeff. is 254*F

Then add to the factor every 10*F you lower the intake air temp. you gain 1% horsepower.

Thats probably the reason I ran 14.6 at only 8psi.

[SmoothCriminal]

hmmm co2 sprayer positioned behind the filter, but directly on the metal of a cold air intake??? blk, could you try it for us?

[BlkZoomZoom]

matt7184- During the summer I went to the track every wednesday night either driving the speed or the scamp or the rx-7. I've run a best of 15.09 (after looking at the slips), with 8psi. Then with the Co2 (probably 30-45mins later) have run best times of 14.67 (done this time exactly 3 times).

I've always dogged it out of the hole 2.2-2.4 60 ft.

Another way I'm pretty much positive that the Co2 works and (works well) is,
- I only use it when stationary,
- I use a full 20 oz. bottle for 2 runs,
- The intercooler is actually frosty when I'm done spraying.

I can't see how it wouldn't actually hit the intercooler being 1/2 away with 2 bars and 24 slits.

You can go into all the technical crap you want, I'm not gonna argue. I am stating what works for me.

[BlkZoomZoom]

matt7184- Yes 1/2" in front of the intercooler with total of 24 openings.

No real dyno plans as of yet, though I do have a g-tech I'll have to weigh the car in.

Just curious, anybody know of a chassis dyno around Albany NY?
I know of several engine dynos, but no chassis dynos that are capable of runnning front wheel drive.
