intercooler Sprayers for FC3S Turbo
 

Don't have pics, they're on the camera though so I'll post them.

I rigged up an I/C sprayer on my 10AE today. I went to the auto parts store and bought 2 "Bug Blaster" windshield washer nozzles for $10. And lost one. And went back and bought 2 more. :) I drilled 2 holes in my hood "in" the hood scoop about 3" before the I/C, inbetween the ribs that there are there, and mounted them there.

I hooked the lines up to the stock headlight washer tank, I just used 1/2 of the output and blocked the other 1/2 off with a vacuum cap.

Results: well evenw ith 1 hose the 2 sprayers once properly aimed SOAK the intercooler pretty quickly. 2-3 seconds coats the whole thing, and water is free, 10 seconds costs just the same.

The headlight washer pump is quite powerful and is obviously up to the task. The tank holds nearly 6 liters (1.5 gallons) which seems to be enough that you wouldn't need to worry about filling it very often.

I've just been using the button to activate it though I'm going to have a toggle switch for it (probably put that in tomorrow).


I don' tthink that ther eare any measureable horsepower gains if the I/C is cold to beginwith but there was a HUGE "seat of the pants" difference if I've been cruising in traffic for 10-15 minutes and go at it from a stop. The car will spin the tires through 2nd now without provocation, and before it would only do that with ice on the I/C so I'd say this was a definate bonus. Not really any difference though once the car is moving (highway)...

Some (but not all) windscreen and headligh washer pumps do a surprisingly good job as IC sprayer pumps. But I wouldn't bother with those nozzles you're using, they won't do squat. For IC sprays to work effectively the water must be very finely atomised, and windscreen washer nozzles won't even come close to that. By maximising the surface area of the water droplets you hugely increase the amount of heat absorbed. This is the sort of spray pattern you're looking for:

This was achieved using a brass agricultural spray nozzle available here:

It shouldn't be too hard to find something locally. :)

while I'm aware that atomized, pretty droplets of water will do a good job, a large volume of cold water pumped onto a hot intercooler will most certainly do SOMETHING.

I looked and couldn't find nice patters like that, the ones that I used spray in a big fan pattern.

I'm going to have a peak at my friend's stage 3R srt-4 that has an IC sprayer and see what it uses.

ahah, im kinda embarresed to admit this but ive rigged up my very own i/c spray using the rear washer resivour, old aluminum a/c line and some silicone hose. Very innovatiove none the least.

That looks so ghetto & cheap that it is inspiring me to do that myself.

dont waste your time

It won't do much other than waste a lot of water. Take some intake temp measurements and you'll see. You're on to a good thing, you just to improve those nozzles. Try someone like Accuspray:

Before making silly comments like this, go do a little research on IC sprays. You'll find they can be very effective if done right.

Hehe, cool. :D What if you grabbed one of those CO2 tanks you get for paintball guns and spray CO2 on the IC?

phase change is all that matters

You would probably just need to figure out a triggering system that would keep the CO2 in liquid form just before the IC, maybe even right on the IC. Maybe could use a purge valve off of a nitrous system and alot of custom plumbing?

Ice water would be cheaper and more plentiful

that was in reply to him doing it my way. :hah:

ummmmm, CO2 sprayers have been around for a while... works great on my friends Evo

Okay, I understand. The idea's good, just not the execution. ;)

As for CO2, it works fine, but it is not available free outta the tap... ;)
