custom intercooler H2O spray?

[JonsTsi]

i was woundering if anyone has or made an intercooler water spray kit. i am thinking about making one using the washer fluid resevoir and pump. i was going to get a fine spray nossle and route a line to the washer fluid line and make it so i can switch between using the new nossle(spraying the IC) and spraying my windshield. i was aslo thinking of using another tank and fill it with a cooler liquid. would the performance benefit from this? it is a cheap set up but i think it would work well. any opinions are appreciated

Its been done before, search this forum for it. I from the sounds of it you want to make a NX intercooler sprays yourself. Might save some money but in the long run it will be easier to just buy the kit. As for the liquid I have heard of them using N20 but it is expensive to refill so the most common used is C02. Good luck and I hope I helped.

I built exactly what you are talking about. I used the washer resevoir in my car for the water because I don't drive my car in the winter so water works fine for my wipers (plus the added bonus of low washer fluid light on dash)

These are the steps that I took:
- disconnected rear washer nozzle hose
- re-routed the washer hose for the rear washer to the front of the car
- installed a washer nozzle in the intercooler duct and connected hose
- Installed an adjustable RPM shift light
- re-routed shift light wiring to turn on rear washer pump instead of light
- installed a toggle switch to turn on/off shift light/sprayer unit
- added a LED to come on when system is spraying
- Installed shift light unit in my dash
- set the RPM, arm the system and it starts spraying at desired RPM

I have no idea what kind of HP gain this gave me, but it was a fun cheap project. Plus it is cool when it is armed at night and the LED lights up when you are spraying

Here is a picture of where I mounted it in my dash:

i did something similar on a friends saab 9-3 turbo

the 9-3 comes with headlight sprayers...so we yanked the rubber hose off and went up to the shop and bought some LED sprayers. hooked up and double-sided taped...and a cooler intercooler

what do u guys put in the tank for squirtin?? Not just water it would be as warm as piss?? Unless u had a bunch of ice ice cold water in a container and pour it in before u pullled up to th line maby!! And where did u sparay it in to?? Could u spray it in ur intake pipe instaed of the intercooler i just bought a new one and dont want a drill holes in it !! thanks!!

I did this on my stock sidemount using two hood sprayers. I had 16g at the time tuned with an AFC to peak at 900C at the end of 3rd and 4th. Using the i/c sprayer after on a pull through those gears after one without had me peaking at 860-870C.

Now you'll probably get a few people on here saying you just HAVE to use a fine mist for this... well, before you assume that's just gotta be the case, ask for some proof. I tried to find some hard numbers on this and I just wasn't able to, and I think most people are coming to this conclusion out of "common sense", which as I hope everyone knows is a terrible thing to trust. I will be trying some agricultural sprayers on my fmic after using some hood sprayers I bought in japan (wide spray patter, finer mist) to give a comparison, but honestly I don't have a clue if it'll make a difference.

As for my reservoir... I'm not really sure what I'll be doing. I don't want to use my rear water reservoir to store because I use my windshield wiper fluid. I used to use a miata's reservoir bottle as it had a long neck, and could be stuck underneath the spare tire with the neck just sticking out the side (for easy filling). Had a coolant sensor put in to notify me when it was low, too. Unfortunately I found the capacity to be just too small. I'm trying to find something larger but I haven't found something to my liking. Honestly I haven't searched much though

i was looking at a c02 kit and figure i can use an air suspension valve and make my own usin like a pinatball gun tank and stuff i hope to do it next week beofr ei go back to the track so i can see if it makes a difference

I use regular water... it is not the temperature of the water that makes all the difference if you are just squirting water.. it is the evaporation of the water that makes it cold.. for example, wash your hands with hot water and then swing them in the air.. they will feel cold and cool down because the water is evaporating

You spray the water directly onto your intercooler not into it... and as said before, theoretically, the finer the mist the better the effect from evaporation

ah yes. the air causes the liquid molecules with the highest kinetic energy (aka highest temperature.....hottest) to evaporate, going sequentually in order from highest to lowest. The liquid therefore leaves the coldest molecules behind, cooling. Theoretically water would not cool as much as CO₂ or N₂O, but would still work. yay for science.

... Yeah.. that's what I meant too just couldn't put it so elequently
