I pull this off of a DSMTUNERS website and i though it may be useful for us. We could learn alot from the dsm's intercooler setup because alot of them have figured out back yard ways of doing stuff. Soooooo what that being said I have I accept no Liability on what happens to your car IE i will not pay to fix your car or pay anything to you if something happens. Little disclamer.

How to make a CO2 sprayer the back yard way
Thu, Jul 20, 2006
Process:

1. First i went to the nearest paintball shop and purchased a special Co2 valve for releasing the Co2 from the tank. I'm not sure exactly what its called. The paintballers use it to carry the tank on their waist wrather than on their gun. I paid 15$ but you could find them for cheaper on ebay.

2. Then i went to a hardware store and bought about 6-15 Ft of hosing. Heat resistant is preferred.

3. Then i bought a few hose clamps and some corresponding plumbing to connect to the Co2 release valve.

4. It's also a good idea to buy some sealent tape to tighten things up to prevent leaks.

5. Make sure the plumbing has a nipple that will fit from the release valve to the hose.

6. You will also need, depending on the size of your intercooler, some thin copper or aluminum pipe or tubing. Its very easy to bend and is sometimes located near all the plumbing stuff.

7. Bend the piping in a spiral and drill very small holes every inch and a half on the side you want to face the IC.

8. Run the hosing through the firewall which is usually in between the battery and the intake manifold, down low.

9. You can run your main unit anywere you want.

10. Fit the sprayer peice you just drilled into the hosing and clamp it really tight. Also try to mount it the best you can with anything. Duct tape works.

11. Also make sure that your hosing is nowhere near any hot or moving parts.

12. Fill up your tanks and start sprayen.

 

be sure to face the tank down so the liquid comes out if not your just going to be blowing air, if the liquid is sprayed it will be cooler... by the time it hits the inter cooler it should be air. Also if there is too much hose, it may give liquid time to convert to all air and its not exactly cold.

 

that helps alot thanks for adding that i cant belive i forgot it.

 

i wouldnt recommend using duct tape...

 

i guess you could hook up nitrous the same way.....lol

why not just spend $150 and make your own c02 sprayer properly?

 

here you go.. if you wanna ***** rig and have a cheap one..

Fellas, there's a nicer way to drop your intake temps by 30-50 degrees. Simply take your windshield washer hoses and run them to the desired location, preferrably the intercooler or any location that the air has to route through before moving to the motor. Drain your windshield washer fluid tank, fill it about 3/4 water. Fill the rest with ICE. Take the car out. Floor it, activate your washer fluid sprayer the same way you always do...feel the power. That simple. Completely stock components, and can save your engine when you've been riding it hard for several minutes at a time. You can even wrap your washer fluid tank with heat repelling fabrics to help keep it cool. It's simple to use, and if your going to race someone, tell them to hold on.. go to the nearest gas station...buy yourself a few cubes of ice, or just take them, lol. Run back to the race scene and use it. Makes a minor difference, but the more ice and longer you spray it, the more power you'll get. Simple. Use this in conjunction with water/methanol injection and you'll have an awesome outcome. The only reason I would advise someone not to use C02 for charge cooling is because C02 is not very consistent. As the temp changes, the pressure changes DRASTICALLY in C02 filled tanks. Every time the pressure changes, the temp of the C02 itself fluctuates. I know this because I was once an avid paintball player. I used Nitrogen/Oxygen in high pressure form. HOWEVER, if you get the C02 cold enough..it will darn near spit dry ice out, which could make a HUGE difference in intake charge temps. Good post though.

 

Hmmmm, that's the 1st time I have ever heard that one. Anyone else done that?

 

It's awesome because you spend ZERO dollars on this setup. You can put whatever you like in the washer fluid tank. Hell, you can leave the washer fluid in the tank. Thats 49% methanol; 51% water. Darn near perfect for injection. Run the hose to your new CAI, (it usually has injector bosses for dry NOS setups) and give that a try. You should really feel a power increase in the seat of your pants from the washer fluid though because it cools intake temps down and combusts better. It would also be more effective AFTER the supercharger though, when the charged air is extremely hot.

 

...yeah its sweet except when you do it, your winshield wiper go up & down... that would look funny...

 

I imagine there is a way to cut the power to the wipers only. I just think it's possible. However, it would be funny to see the expression on a Mustangs enthusiasts face to see you pull away from him while operating your windshield wipers. LOL.

 

HAHA... I was actually thinking of making it a sprayer for the new h/c I"m installing... doesn't seem like a bad idea, but using it for w/i I don't think it has enough pressure to atomize properly, you'd probably end up flooding out your motor.

 

Yeah, that's why I initially said to use it in conjunction with an actual w/m injection. I think both of those would net some serious power gains. Especially good for those that boost 17+psi into that heap of a charger.

 

I'm runnin 20.6 psi right now.... I need w/i bad.... ordering it today... my **** gets rediculously hot after a few blocks... now with the heat wave...I"m afraid to punch it.

 

shoot this directly into the intake? i might have read it wrong..... be carefull if thats really what your saying to do though itll hydrolock and can cause a huge chain reaction throughout your whole motor

 

Hey guys sorry i havent posted lol. The window washer fluid is great. I just wanted to do a post on the Co2 because i see alot of people wanting to may alot of money for it. you dont have to use duck tape either. I think we really need to find ways to do free mods or cheap mods. Nothing of coarse that would damage the engine. for example adams way is a free mod pertty much.

 

the biggest issue with windshield washer sprayers it that water freezes. the CO2 ones don't have that issue.

 

Yeah, apparently there are kits that just spray water into the intake. I'm not an accountant, but I was always told that would be a bad idea. If someone here can explain why this is a good idea, please explain, I'm lost in the sauce on this one.

 

i thought he was spraying the water onto the intercooler, not the intake.

 

I think that was the original set up, but then actual water injection became a subject, I could have read the really long post wrong though.

 

No, I would only inject water/methanol into the intake, but that's not gonna work anyways unless you can replace the cylinder that pressurizes the washer fluid injectors with a higher pressure cylinder. Water/methanol injection needs a high enough pressure to completely atomize so the injection acts as a coolant and a fuel additive. I believe it adds comprssion to the motor without adding the harmful effects. As discusses already, I meant to inject ice water into the intercooler, aftercooler, or something of that nature, or something with the purpose of cooling your air intake charge. Injection in the intake, or after the supercharger would need to be water/methanol, which is what windshield washer fluid is exactly. And personally, I wouldn't do any injection UNLESS it was a freakin hot day, or humid...or in my case, both. It's not uncommon to get up to 100 degrees where I live and with a humidity of 50% or greater. That takes away a substantial amount of power from a motor and the motor is also more likely to over heat because the cooling system cannot keep the engine chilled. However, you can always use the 10 minute method of washer fluid pumping, so I call it, and chill SOMETHING related to intake, or charged air. If you have an intercooler, this would be the ideal place, NOT the intake charge pipe. Put water/meth injection kit ($300) right after the super, and washer fluid filled with chilled water around the aftercooler, before or after, doesn't matter. This I think would help greatly for high boost applications using the Eaton chargers on a hot day. CO2 is a great idea, however, I wouldn't spray anything other than the engine bay with that stuff. Chilling the engine bay itself would help alot. It'd be like a super fan for the radiator or HE.

 

If it's that cold outside then you obviously don't need an extra chiller or fuel additive for the engine. Water/meth alone would do the trick for power on a day below 33 degrees. This mod would be an insurance of engine safety mod--> just something there to help regulate a normal operating temp for the engine, especially in the summer, or in hot regions. That's why I say use this in conjunction with water/meth and you should see big results, especially those who are running 20psi boost.

Might I also add that even if the water froze in the washer fluid tank, the engine bay would obviously heat up very quickly and over a few minutes, could easily melt the ice, further more making it chilled water again.

 

i'm more worried about splitting the tank open, lol. besides, i kinda like the windshield sprayer. it's one of those "nice to have" items

 

True

 

man i am still lost, call me a noob but i have a n/a 2.2 if i hooked the water sprayer from the wipers up to my intake and sprayed it in is that ok by what your saying, or is this only really for the supercharged engines
