Interesting water cooling article by Garrett

If the link goes dead, search for "water cooling" at http://www.turbobygarrett.com.
Perhaps the most interesting point for me was that the bearing races are only rated to around 300* F!! These races absolutely rely on proper cooling of the center section.
The other interesting point for me was the 20* rotation of the turbo for proper siphoning. It's actually opposite than what I would have expected.

It's not a highly technical article and might not cover everything but still a good read.

im about to replace my turbo with a garrett so i read a lot, the article really makes the water lines sound very neccesary for daily driving, i mean people say meh just stay more in the car to those i ask, if you were about to die, and had the chance of buy some extra minutes of life for less than 200 dollars, wouldnt you?, just think about it, staying in the car after you arrive your destination isnt the best idea lol, by not installing water lines you just waste your time


about the 20 deg rotation, i was just like you, i would have done the oposite lol

Very interesting... I would have thought that the turbo would have been way to hot to route water though especially like is stated in the article with a picture of a glowing turbo manifold.

While I was reading I was also thinking most turbos I have seen the manifold all wrapped in heat wrap and a turbo blanket which will just keep even more heat in the turbo

makes you wonder if a company would make a water pump delete kit which converts it to an electric pump so you could just add a timer and keep the fans and water flowing... is there life expectancy and reliability to use mechanical vs electric?

Also don't some cars keep the radiator fans blowing for a specified time. The focus could be rigged up to at least also keep blowing air also over the turbo and possibly keep the cooler water still cool helping the thermal siphoning.

Well WTF, were did my post about this go?

Why was it deleted? Did a drama fight start in here and it was accidentally deleted?

This also supports the installation of a turbo timer to prevent varnish and oil breakdown in the turbo on shutdown.

I know this may be a little off topic but where would you hook up the water lines for the turbo? I just got a turbo that has oil and water lines. I know where to hook up the oil lines but not the water lines.

you'd hook it up at the lines to the heater core by cutting them and inserting T fittings.

See the starting paragraph on pg 6... it goes into fairly good detail (for non vehicle specific) on his it should be plumbed and installed.
