What ever happened to after-run cooling systems? All my old Audi turbos had a system where the low speed radiator fan would switch on in conjuction with a small electric water pump to cool the engine and turbo bearings down after shutdown. Pretty cool. Over engineered? Sure. Effective at minimizing coke deposits on engine parts and turbo bearings? I would think. The new Audi and VW turbos seem to have done away with it.
