why not get a front mount intercooler, and nitrous express intercooler chiller. That would be worth the wrench time and would work 100 time better than a watter sprayer

You ARE dangerous.....

....but probably right.

Using the rear wiper resevoir is an easy way to keep cold water to spray the IC with. Also, the temp diff between the IC and the water is going to have to be astronomical to cause some sort of damage thru thermal shock. Like water just above freezing and an IC at like 200+ degrees. Only time i've heard of water cracking steel thru this process is when WRC cars drive thru some water with superheated brake discs...

If this was such a nono cars wouldn't come with IC sprays out of the factory, like the new Evo 8.

I've noticed pretty good results with my rear wiper to ic spray conversion and have pics. worth a "how to" write up???

hmm...didnt think about the heat in the engine bay, woops. guess ill mount that in the back somewhere, o ruse my wipersprayers

Hmm,

So for $3000 CDN for a Greddy 3-row and the N-tercooler I can use nitrous instead of water.

I've spent $1.50 CDN for water spray so far, though I already had an M2 Medium intercooler and leftover hose.

Re-filling a 15lb nitrous bottle around here costs $55, and the N-Tercooler I've seen in use looked like it would drain that in about 30 seconds, tops.

Water, at my apartment anyway, is free. It usually is pretty cheap trackside, too. Once I get a spray pattern I like, I'll get about 10 - 15 minutes out of the washer resevoir.

I'm looking for maybe a 10 degree drop in intake temperatures using water spray. That would mean the N-Tercooler can drop air temperature by 1000 degrees


I think you can tell which one I think is "worth the wrench time"

TYSON

And Nitrous Express would probably have lawsuits on their hands the first time somebody used the N-Tercooler to spray -130 F vapour onto a +150 F intercooler.

Do the how-to for using the rear washer pump. I think I covered using the headlight washers, but I think they were easier.

I had the write up F'N DONE. pics inserted where necessary, i hit post, got the "post once every 30sec" message, hit back and it was gone. maybe i'll try again when i'm not so pissed off.

racerfoo

dang....well thanks for the attempt airborne...im interested in that setup...a little less ghetto than mine :P:

True...the greater the difference in temperature the greater the damage, but it is all time dependant. So if the difference is smaller, it will just take longer. If enough damage is done, rust would prob take over anyway.

Just a word on the ntercooler kit... It is awesome... ive seen a car on the dyno at my shop use it and it made about a 20 horsepower difference. however it is pricy to spray nitrous into nothing like that... if I were to do it I would probably look into getting the bottle filled with C02

Am I the only one that can't be leaking fluid on the track? If you used Ice water in the tank that would be good, however that wouldn't last long before it came back up to under the hood temps. I agree that the hot water would give a warming effect to the intercooler, but it would also increase the intercoolers efficiency because the water film on the intercooler would release heat better than the dry fins would. I think you will find that when you first spray the IC that your intake temps will raise slightly, and then decrease below the orginal temps as the intercooler starts to dry off. Also with all of this water leaking out underneath your car, aren't you guys concerned about traction?
If you spray the hot water on the intercooler before your run and no air is going through it anyway, I don't think you would see any intake temp increase because the surrounding air is the same temp. So I would spray the water on before boosting give it a second change to the air temp, and then boost. It's alot of work though. Someone should do some 1/4mile runs with this setup to see how it works.

airborne

This is not hard info but I showed my setup to dave@KDR and he mentioned a T2 guy who had created an IC spray for his car. sprayed it before a run like crazy, steam and **** coming out the T2's scoop and all. supposedly knocked a quarter second off his time. of course any advantage you gain is going to be relative to how hot your intake air is pre-spraying.

if you use the rear resevoir the water may come up to the ambient temp but not likely higher...

TYSON

Good point, but mine will be on a road course. I'm trying to choke down the flow to the point where hopefully nothing is dripping.

Hey wanna be monkey boy Maverick, IC's are ALUMINUM, not steel! Rust isn't a concern, only the slightest possibility of corrosion.

As for dripping fluids the flow from this will be a vapor and will be smacking right into the hot engine, so dripping wouldn't be a concern unless you were sitting still.

Wanna-be-Mav, maybe you should buy an FD and re-take your high school physics class before you start making whacko "no-no" comments about evaporation and IC's.

I wouldnt say corrosion except maybe from Electrolisis (metals in water reacting to the aluminum. Its a chemical reaction of 2 different metals to eachother.) Also oxidation would increase. This would take years and is insignificant. The water injection is a better solution than an intercooler sprayer.

jetmech77

MAVrick if you do have a degree in this stuff you would know a little more about thermodynamics......think of any swamp cooler/ evap cooler on all the homes in the southwest. Water evap makes things "COLD" It should not matter one bit of the temp of the water hitting it...All you want the water to do is evap anyway. I have also heared of people adding a % of isopropyl alcohol...that really has a fast evap point!!
BTW...has anyone mounted a temp gauge to their intercooler?? The air going in has got to be pretty high!!

i been thinking about this for a while.. and I have completely gave up on the idea about shooting NO2, H2O, EtOH, or shooting propane to throttle, what ever.. I think all is fairly quick fix later you have to "fill" something..

I been doing some research and one I could think of is the liquid air intercooler.. which is proven to be very efficient.. But my latest idea is combination of liquid air IC and Air cool IC.. Hook the Liquid air first, since H2O will heat up and reach above ambion over time.. And then Front Mount IC will cool the temp down.. I was thinking about mounting liquid IC radiator on second oil cooler location.

The debate is, some say, it will be heavier (have to have about 1 gal of H2O circulating).. and wouldn't it benefit better to put liquid IC after Air IC??..
That I don't know.. i'm currently in search for small tubular Liq. IC.. that could be mounted injuction to Air.. I've seen few that might work.. But with limited fund and time, and other things I need to do, its just in working idea..

I think some have gone with Liquid IC.. but I haven't seen combination of two..
