Has anyone tried hooking up the windshield washer pump to nozzles attached to the intercooler? Im wondering if this will help with power? Lower EGT's ?

The SRT-4 Neon stage 3 kit from Mopar adds washer fluid nozzles attached to the intercooler to cool intercooler in order to increase power.


Just wondering if anyone had thought of this or has any opinions or feelings about it.

 

Sounds like it would work.

 

A lot of pullers do that. It uses a good bit of water, but it's effective. It's mainly for EGT control.

 

you may have a small problem... What is the psi of the air in the intercooler.... then how many psi does the washer motor push?....

The washer motor will have to push more than the turbo does or you will just be blowing air into your fluid resevoir.

 

Were talking about spraying over and onto the surface of the intercooler not spraying inside of it.

 

My Dad's Subi WRX STi has a spray bar mounted over the aftercooler. I believe it only works at full boost and for about 10 seconds. And it does work!

Now Thats funny I don't care who you are! GIT-R-DONE!

 

i've thought about doing something like this, but i can't justify doing it right now [i have no EGT issues] but i've been thinking of a little 12v pony pump [got 3/8"npt in/out] and a whole mess of them little garden irrigation misters... it would drain down a few gallon container of water in a hurry though...

 

maybe this would clean up those dirty injectors

 

Actually, that setup is in a few production cars, and the general consensus is that it doesn't work _THAT_ well. You can't use alcohol because it would corrode the al. ic. Most people with evo's don't bother with it, because it barely works, and you have to use it _BEFORE_ you heatsoak the motor, and continue using it to prevent heatsoak.

 

I think we're talking about two different spray methods here. Spraying water, alcohol, or a water/alcohol mist into the intake tract does indeed work very well, at least on gasoline motors. You don't have to do it before the motor heatsoaks, either. Done properly, it drastically reduces the octane requirement of the gasoline you run.

Spraying the outside of the intercooler also works, though it doesn't work as well as injecting into the intake stream, since you don't get the benefit of extra fuel being introduced, and any cooling effect on the intake air must first make it through the intercooler to affect the air.

Now, if you have a system that's only marginally effective to start with, you might not notice much effect if you wait to use it until the intercooler/engine are good and hot. But, that would be more because the system was only marginally effective, not because of anything inherent in how it works.

There are currently alcohol/water injection systems out there that spray high pressure mists of the mixture into the intake tract. Their output is based on boost, and they work extremely well on forced induction gasoline engines. They often allow engines running on 93 octane pump gas to safely get away with 26 pounds or so of boost. I have a friend with such a setup on his '89 turbo pontiac TA that does just that.

All this said, how does it affect diesel engines? I have no idea how well injecting into the intake airstream works, but spraying the exterior of the intercooler should work fine. That is, if you spray enough to really cool it, and intercooler effectiveness was a problem in the first place.

 

Well , Ive got the nozzles mounted on both sides of the intercooler now and I was also able to move the a/c condenser down about 12 inches so the intercooler could be introduced to some cool air from the grille. I mounted a switch inside the truck. Now all I have to do is test it out to see if EGT's are dropped. I do not have a dyno near by so I wll just have the setup in place and try it when I race some of my friends over the weekend next week

 

Yes it does or should work. Mitsubishi uses it on its Evolution Lancer. Works well from what I am told buy a friend how owns one.

 

I have seen a few people that spray their nitrous over their intercooler and get drastice changes

 

I added a few nozzles in my jeep cherokee to cool me and a passenger down through misting water. Still have to Run the hoze and nozzles to the radiator. The thoughts on evaporative cooling are quite intriuging as since the water is so small it hits the hot surface and evoprates immediately, sucking the heat away with it. As far as the intercooler, it should work well as long as it is hot enough. Should be though as I hear the compressed air can hit 400 degrees. Might not help much but I would bet it couldnt hurt either.

On a side note of water cooling, I saw this program on big rig racing over in europe and these trucks used gallons of water sprayed onto their brakes to keep them cool. It was sweet to watch the amount of water.
