Turbo Cooling: Water vs Oil only

[heartbrkr]

I'm under the impression most turbo's also have water feed to help keep them cool. But was listening to a guy who had oil only.

Is there any pro con to this, im assuming oil only would be cheaper, or am i totally lost? =)

Simplistically, the current stare of the art in affordable turbos is ball bearing cores with water cooling, the oil flow cools a bit but water does most of the work. The common (as they have been around longer) plain bearing turbos use the oil to cool them, they need higher oil pressure and flow (than ball bearing turbos).

If you want to know more, do a search, there is plenty of discussion on this.

That sounds about right.

Both water and oil cooled BB turbos is it.

You might see some Trust units which are oil cooled only.

That's fine.

You should have an oil cooler in this case.

On the plus side, this puts some pressure off your radiator.

Not if you put the oil cooler in front of the radiator, it actually then adds pressure.
