After running it hard 2 min cool down.How long should I let the turbo cool after driving the car? I try and take it easy the last mile or so of my drive, and I let the car idle for about a minute before I shut it down. I don't want to cook the bearings. I've heard of problems w/ aftermarket alarms and turbo timers.
If you drive down the road not hard, don't worry about it too much.
If you are that concerned about it get a temp gauge and put it in the turbo mani.
