GT35R, about water cooling hookup
For all the guys that think they can just cap off the water lines on the GT35R. I still think you need to let the car idle before shutting off to cool down the oil a bit. As everyone knows, coking shortens turbo life.

Re: GT35R, about water cooling hookup (Pikachu)
So, is it saying that water cooled turbos don't ever get above the coking threshold?
Where'd you find this one? I remember there being a graph in Maximum Boost about the differences but it's a little different than this one...
Either way, my turbo is water cooled
Oh, this graph isn't specifically for the GT35R is it? It should be the same for all turbos... right?

Yea it's basically for all turbos that are water cooled. I wasn't sure all BB turbos are water cooled so I didn't want to say all turbos.
sbiggi, a turbo with water cooling basically never cokes or so the graph says.

Re: GT35R, about water cooling hookup (sbiggi)
on all of the gt series turbos, you have to hook up a water source to it, or else the bearings will fail
also, without water cooling (on non bb turbos) the oil will not coke as long as oil is flowing through the turbo, oil only begins to coke after the flow of oil stops, so the remaining oil just sitting in the turbo begins to coke.
Also, the only reason we have problems with coking today is because of the multi viscosity oils, if you can find a single viscosity oil, like 30w, then you dont have to worry about coking

yeah but according to the graph its going to coke the oil while the car is running too. I can read the graph... and a water cooled turbo will still coke after you shut the car off if the turbo is hot.
The point I'm getting at, is that the graph looks like it was arbitrarily drawn.
I wouldnt rely on that graph for making a decision on wether or not to run a water cooled turbo.

Re: (Pikachu)
no, it will still coke if the temp is high enough. there are additives in multi viscosity oils that cause coking, mainly the detergents ( ibeleive) single viscosity oils wont coke, but they are a bitch to find and generally arent synthetic
