You should look up oil coking in turbos, and why turbos became oil cooled. Something something specific heat something something equilibrium temp something something.

I'm well aware of coking and why turbos finally went water cooled. I was spinning wrenches at a SAAB dealership when the first load of water cooled turbos came in back in the mid 80's. Old news, and all fine examples of why there's an
oil cooler on the DIT motors which seems to do a fine job on street cars.
