Thank you for posting the information about brake cooling.
You are right, there are teams using water spray to cool their brakes. Not many but at least one.
There are also teams using water spray to cool intercoolers on turbo charged cars..
My comment was directed specifically to the use of water spray to cool 911 Porsche engines. My comment was "No top flight team that I can find uses this nonsense. If there is someone out there running this solution, I would love to hear from them."
I guess from your answer that you know of non.

... but we can certainly expect that Rubbermaid Solution to pop up everytime someone mentions high temperatures. I have nothing against innovative ideas but for as many times as we are force-fed that contraption it looks as if someone else would have made one also - I know of no one else that has tried it. The design itself is flawed and I for one do not wish to douse the alternator with a continuous stream of water. As I have said before, it just really gets old...

Before anyone attacks me, please allow me to clarify. I am a believer that controlled moisture in the air can be a great contributor to reducing air temperatures. I have spent a considerable amount of time studying psychrometrics; however, seeing this Rubbermaid Solution touted time and time again by only one person is becoming a sad joke. It is not psychrometrics but instead is simply spraying water haphazardly in the direction of the engine. There is a big difference in the two. I, for one, think it is a very foolish thing to do (though we have to endure 50,000 posts on the Rubbermaid subject). What a terrible waste of bandwidth...

I don't have that radiator--just "trombone tubing" that twists up and down a couple of turns.

I've asked separately in this thread whether replacing the trombone with a radiator would cool the oil more. I have a leak in the summer when it runs hotter, but no leak in the winter. All these oil leaks I suspect are mostly about too much heat.

Henry,
Perusing the pits at the last few LBGPs, ALL competitive TransAm teams used some sort of water spray brake cooling system - mostly shop-built. Our product seem to provide the correct amount of cooling given the delivery volume of the nozzles.

Large oil coolers and direct air flow seems to do the job on most 911s. A cooling system that works without replenishing the cooling medium is always preferred, if possible.

Water spraying an intercooler has secondary benefits. The reduced air temperature or excess moisture from spraying an intercooler normally services the cooling system whether it be air (cylinder heads) or water-cooled (coolant radiator).

The only limitation is the size of the coolant tank and the weight of water.

Yeah--that's a good point--the main reason why the temperature corrects downward quickly when that radiator fan comes on.

I can't help but think all those oil leaks in the air-cooled 911s are due to the lack of adequate cooling of the oil. Oil has a lower thermal conductivity than water below 100C--by a factor of 4.
