Hey guys. Just a quick question. This goes for the CT26 and other water cooled turbos. Is there a draw back of not running water in the water cooled turbos. The reson I ask is, besides most stock turbos, aftermarket ones are not water cooled. Besides heating up your coolant to near boiling tempuratures i guess i dont really see the reason. If some one could shed some light on the subject i would apprieciate it. thanks everyone for your help.
7M Turbo Water Cooled

If the turbo is meant to have have running through it, It should.
As for oil cooled only turbos they usually have some other sort of cooling like smalling center cartridges which allow more air to go thru thus cooling the oil.
but for runnning bothe water and oil, i guess its a way(old) of better cooling the turbo.
thats the way i see it, so hope it helps.

Thanks for the reply. Currantly I am a ATS 60 Trim turbo which is both water and oil cooled. The darn thing keeps having issues with the coolant lines, and it just makes my coolant temps so much warmer then my last non water cooled turbo. Do you think it would do any harm to not run the water on it?
If it's designed to use both, you're just asking for trouble eliminating one. What kind of radiator/cooling setup do you have?
You answered your own question. If the coolant boils (which it doesn't) don't you want the coolant there to handle heat rather than replace them from coking?
All turbos need oil, but the 7M turbo isn't oil cooled. The oil is there as a lubricant, not a coolant. The water is supposed to handle the cooling job. Remove the water, and you'll have crunchy carbon grit instead of oil in your bearings in no time.
some turbos are oil cooled, and don't need water. I suppose that you COULD run oil instead of water through a water cooled turbo. Probably wouldn't do it too much harm, but the cooling passages are different from the lubrication passages.
I've been given to understand that water cooling is superior to oil cooling. The water can remove more heat energy. Even if it does have localised boiling, it will keep the temperature lower, which means a longer life and tighter bearing tolerances for rotating assemblies.

It's true that it does do so, but that's not it's purpose in a water cooled unit. Any circulating fluid which is cooler than combustion will perform some cooling duties, but in the case of a water cooled turbo, like the CT26, or my Turbonetics, or the OP's ATS, I would not expect that it would last long at all with no water going through the unit, same as the oil will not work to keep your engine from overheating in the absence of coolant. As I stated earlier, it MIGHT be able to survive if you were to pump oil through the water passages instead of coolant, assuming that the seals will stand up to oil, but I wouldn't make any bets as to the longevity of such a setup.
For all practical intents and purposes, there isn't enough volume of oil present in a water cooled turbo at any point in time to provide anywhere near adequate cooling, and as such, I felt it better to present the lubrication system as being completely separated from the cooling system.
