Default Turbo cooling issues. Where is the hot spot?

I don't have a turbo timer. I'm not patient enough to sit in the car for a few minutes before turning the engine off. Does it make difference if I make sure that the engine is not under a load the last few miles of driving? Isn't it true that if the engine isn't under load, the turbo isn't working at all and the coolant is still flowing and cooling it off? If so, it is probably a good idea to run above idle while cooling off in the driveway.

I'm alsowondering what part is the crucial spot for coking of the oil. It is inside the turbo housing, or inside the oil line that runs over the turbo?

okay. first ist not coolant, its oil running through it. and secondly, just for the last 5 minutes, be gentle. if its not in the boost, then ur not pressurizing air, then the air deosnt get hot meaning the turbo gets cold. even if ur a little in teh boost, it wont hurt it. just be gently the last few minutes. nad big sign ur turbo is too hot is when it looks like a lightbulb. thats bad. as in bad bad. as in dont-turn-it-off bad...

^^its actually oil and coolant running through the turbo

but he is right about one thing, just stay off of boost for the last bit of your drive and your turbo will really appreciate it.. if you are on the go a lot like me then a turbo timer is a cheap and nice feature to have. less than a hundred bucks and super easy to install

It can kick in as early as 1950 rpms from my experience. It really matters how much throttle you are giving it.
