Trans cooler water mist spray

I was bored this weekend and decided to set up a water-mist nozzle to spray onto my intercooler and trans cooler. I couldn't find any threads on the topic so I figured I'd start one.

I just fabbed up a little mount that hangs down into the space between the IC and TC with an 0.75 gph nozzle pointing down to spray onto the IC and TC whenever the water injection system is turned on.

I already had a water injection system set up for the truck and had one of those 0.75 gph nozzles from Devil's own (I was curious what they were like so I bought one to check it out). I had thought about setting up a second water-injection system that would have the 0.75 gph nozzle spraying pretty much any time the truck was in gear to see if there were any fuel economy benefits, but decided to try this instead and see if my trans temp runs any cooler.

I used the small nozzle because I wanted to make sure that the water volume would be low enough for the water to completely evaporate.

I took the truck on a 1.5 hr trip and it did seem to drop my trans temp a couple of degrees. It's a trip I make often and know I hit about 165 degrees on a typical summer drive and I didn't climb above 160 this time. I really don't think the 0.75 nozzle is enough to make much difference...so I might have been babying it a bit more trying to force a temp drop. lol

Just figured I'd start a thread to hear if anyone had any comments on the matter.

Going to take ALOT more water to make any kind of impact doing it like that. At least 6 nozzles spaces out...

You would be better off installing the nozzle inside the intake post intercooler...

Get a 6.0 trans cooler and use the water for injection in the motor. It will be more efficient that way

something else.. to watch is when the water is misting on the hot parts the water will boil off an the minerals will be left on the parts.. ..seen it done on ac coils.. (IM A AC MECH)

Good point, hadn't thought of that.

I have water injection for the motor (two nozzles & 9 gph total), this is just an additional line off the diaphragm pump to make use of the 0.75 gph nozzle I had laying around from the purchase of the other nozzles.

I plan to upgrade the trans cooler as part of my PMS. This was just something to play around with to see if it makes any difference...plus it only cost $12.75 for the nozzle. lol

Here's a pic of the post IC nozzles for the water injection.

It can work, however it takes A LOT of water to make a noticeable difference...

I thought about using the 5 gph nozzle but was worried about it being too much volume and not evaporating on the IC/TC surface and/or pooling on the floor
