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.
