I would say that a couple minutes of cool down idling would be good. I always let mine idle for a minute or two regardless of the type of driving. I dont have any comparison data for this though.

I have however watched the bare turbo with the infrared camera while it has been idling after some aggressive runs. There is "sweet spot" so to speak of time. I watched a bare turbo at 550F idle down to 400F in that couple of minutes.

The normal operating temperature of the bare turbo at idle is around 350F, until driven then it wont dip much below 380F-400F at idle.

Extended idle times can raise the temp back above 400F.
