Here is one of our subaru kits we finished not too long ago. Twinscroll, Borg Warner turbo, Dual Tial wastegates, stainless and all v-band connections.
Oh, I see what you are talking about now. I could not see it on my phone yesterday. It is a water and oil cooled turbo. Most of the ball bearing turbos and even some of the journal bearing turbos are now water AND oil cooled.
Ok, just ignorance on my part. I thought that was what I was seeing but I didn't know any turbos were water cooled, all I had ever been around used oil only.
A lot of the new ones are. The "theory" is that it will prevent oil from caking when they are shut off without cooling them down first. Most gasoline turbo cars are water cooled these days.

Im sorry but that 'Theory' is crap in my opinion. its just another way to get away with being LAZY!!!!! and not letting your turbo idle down properly to cool down before turning off your engine...gas or diesel!

I agree. As I stated we try not to use them when possible, but some turbos don't come without the water lines.
Running water to the turbo for more cooling is LAZY? I would call it stupid and useless. Another whoop dee do for an idiot engineer. Oil and water temps run about the same temps together unless your running in extreme heat temps,hot or cold. Thats what i have seen in all the years running big trucks up and down the highway.
When I started driving in the early 80's it was recommended to let the turbo cool down before shutting the truck down. As the years ran on the manufactures started saying not to wait and shut it down when you got parked
While oil and water may be the same temp, oil does not continue to circulate when you shut the key off like water does. I believe from an OEM standpoint it prevented them from having to replace turbos as often for people that would not wait to shut the car down like they were supposed to.
you should never run brake line for your oil/water feed lines to your turbo(s). Y not?
Because brake line doesnt flex with engine torque. And what do you mean by electric turbo??

I've been a driver myself for many years and no matter what truck I have/had where I was or what I was doing I ALWAYS let the turbo cool down!!! The Idea behind running water is so you wouldnt have to idle down your turbo to cool it down. And Im sorry but not letting your turbo cool down after a days work (no matter what it is) is plain out lazy and stupid!

What makes you think water continues to circulate when the engine is off??
Pressure in the system allows it to continue to circulate and a mechanical thermostat will still open. It is not being pumped, but the water passages are large and open enough to allow thermal movement without a pump. I have spoken with turbo engineers about this as I am leary of oil and water cooled chras after having the two mix when a turbo went bad.
Is'nt that one of those blowers you carry around in the summer.
Hey if we can figure out how to put a water sprayer on that. I magine the money to be made. Investors are waiting!
