It doesn't matter if the coolant is a little over 200F versus maybe maybe 50F degrees cooler...
The turbo (CHRA) gets a LOT hotter than that.
The reason to run coolant through the turbo is to keep the oil from coking in the center.
We're talking preventing the oil from hitting 300F+.

Nicely put Ted, but don't non water cooled turbo CHRA's see way above 300 degrees?
Are they designed differently to reduce coking?
