Well i just got done reading about some people rerouting the lines from the rear washer to spray the intercooler. I got to thinking, and decided to yank the washer bottle from my wrecked daily driver suzuki swift. the bottle is about 1/2 the size of the stock mazda battery, and there is actually a place to bolt it right in, where the stock battery goes. so since i am relocating my battery anyways, i am going to have it screwed in there, with the lines ran to the IC and a power switch hooked up in the cockpit. I will post pictures when i get it all finished, here's what it looks like now without the filler neck removed, and not mounted...it doesnt look bad just sitting there.

hmmm, I'd like to see how this turns out

artguy

you need a different intercooler...you might as well be pooring water on a grease fire with that stock one ya have.

lol...stupid stock intercooler...its good for nothing!

I saw on Motorweek that the EVO has an intercooler sprayer too.

i actually just did the rear wiper to IC spray, have a bunch of pics i hope to post today. i didn't use the "whisper one way aquarium valve" and mine does leak but thats the only problem. it works well. i have a pettit cc2 ic.

of course with open intakes i've found the problem is not the intercooler, its the air around the intakes that heats up and raises intake temps.

What's that white bottle to the faaaar right on that picture? It seems all US FD's have one. My Euro-spec doesn't.. Looks just like the overflowtank at the other side of the enginebay.
If I install that, it may be used to spray my FMIC.... Hmm..

i think you're looking at the windshield washer resevoir tomco...

has anyone else done the rear-wiper-to-IC-sprayer mod? if so what valve did you use to prevent leaking? is it just an air check valve? this is what i'm talkin about if anyone could help

"The problem at this point is that the hose will continue to siphon the washer tank after it is used, so your first application will also be your last. To prevent that, I created a siphon break by putting a tee and a short length of hose with a Whisper one way aquarium air line valve at the end, on the hose at a point above the washer tank at the back of the car. It is important to create a fairly sharp bend in the hose and put the tee at the top of the bend for maximum effectiveness. The one way valve prevents fluid from squirting out under pressure, but air is pulled in to the hose, breaking the siphon after the washer is turned off. (The end of the valve that you CAN'T blow through is pointed toward the tee.) Use the sprayer for a second after filling to make sure that any siphon that was created during filling is broken. "

Do you guys have both a front AND a rear washer bottle?
I have only the rear one.

airborne

some FD's came with a rear wiper, only those have the rear resevoir. all come with the front one.

are you saying the resevoir for the front windshield wipers is in the rear? trippy...

Tomco78

All the fluid for my rear wiper, front wipers and headlight washers are in the rear.

airborne

headlight washers??? woah. i saw them mentioned in the workshop manual but i thought it was just a myth, or an urban legend or something.

Tomco78

Actually... I COULD just move my hadlight washers and use them to spray the IC. That would be very easy and would work for sure.
I have not used the washers ONE time! Maybe just tested them when i bought the car. Don't really know why they're there...

The engine bay gets pretty toasty. Upwards of 140 to 150 degrees.

With a bottle mounted right in the bay, the fluid will also get pretty hot.

So will spaying 130+ degree water onto the IC actually provide any significant cooling?

Are there any issues with dumping fliud on the IC and maybe whatever is behind if)? If you live in cold parts you can't run pure water.

Rated R1

Yes it will provide cooling. It is the evaporating of the water that cools the intercooler. Kind of like how sweating is effective.

ech

I understand that, but if the water is hot I don't think it's that simple. The hot water could add more heat than the evaporation removes. Sweating is effective because the water is the same temp as you. Would be even more effective it were colder, and if it is hot enough, you get burnt (evaporation asside).

If the IC fins are near ambient, and the water is say 40 deg hotter.... damn I wish I remembered my HS physiscs.

An extreme example: Have you ever had a coolant leak spray your radiator with superheated fluid? Even though there is a lot of evaporation, it still renders the radiator useless - car overheats very quickly.

Canadian models only They never wash so these were included.

Somebody needs a bitch slap!!

I just redid my headlight washers to be used as an intercooler spray. The Haltech E11 has a function to use an output for this, so I thought what the hell? The headlight washers have twin pumps and a check valve at the front of the car with the 'T' fittings.

I disconnected the stock hoses from the headlights and ran Silicone Hose Techniques 4mm windshield washer hose (came with the kit) from the the 'T' behind the drivers side signal light and up through the nose. The sprayers I have now from the hydroponics shop, (potheads ARE good for something ), have a spray pattern like a slightly flattened umbrella, so they aren't much good. He had a couple others that I will try to see if I can get a good pattern.

A problem you might run into is that the headlight washer motors pump out a lot of water. I think the resevoir holds 4 liters and it took about 30 seconds to take it down a litre while I was adjusting the spray. I am going to try putting my stock turbo pills in the line as restrictors. I bought the D-luxe sprayers, and they cost 75 cents , so a little experimenting is in order.

As for wiring, I tapped the wiring to the switch in the centre console to the output on the E11 (ground on the washer relay). I then had to splice the positive on the relay into constant 12 Vdc at the connector under the deadpedal, or the system would only work with the headlights up. The E11 now turns the sprayer on when the air temp rises above 40 C and turns off when it drops below 35 C. (these are adjustable, of course)

Now I just need to make ducting for my intercooler that will hold the sprayers

holy **** that's ghetto. props for originality though!

TYSON

Who are you calling ghetto?

R1TT

Yo Tyson, wicked, let me know which nozzels you got I wanna get a few too

Brad

Yo mama, punk!

lol....I was referring to the first pic racerfoo posted.

Crashunit

I did this along time ago with my front windshield wipers along time ago and didnt really see any significant changes in IC temps when I sprayed it to my FMIC while driving on the Freeway. The only down side to this was that it would leak after awhile after spraying. I had pics of this before the forum gallery went down. If anyone is willing to host them I will gladly post them to see what they looked like.

TYSON

The ones I have now will probably work good for you. You could mount them about 3" in front of your intercooler and they will reach from top to bottom. I'll pick up some more and let you know when I'll be in town next. Probably Friday or Saturday. Car runs, just need to baby it up to Woodbridge for tuning.

Crash,

The check valve in the headlight washer system seems to be keeping mine from leaking. It flows like crazy though, only takes a few minutes to drain the tank. I need to restrict the flow.

Spraying hot *** water on your intercooler is far from being classed as "evaporation".
When the water is sprayed on the intercooler, it is either going to be cooler or hotter than the intercooler itself. And when the water and steel contact each other, they will try and balance energy (heat in this case). If the water is hotter, then it will have negative effects. If it is cooler, then the water will temporarily absorb some of the heat energy from the actual steel of the IC so that the water and steel become the same temperature.
With the smooth steel finish and the high velocity of air passing through the IC, the idea that the water will infact evaporate is a bit of a joke, especially considering the water in the engine bay will be hotter than IC.
Even if you could get water that was cold to sray on IC, spraying cold water on hot steel is no no.
