Turbo

If you have just given it heaps, then yes it is a good idea to give the turbo a few min to cool down before turning the car off.

most of that is common sense. how many people would thrash the hell out of it and switch the engine off after dropping from 5 grand to 1?... most people would give it at least a bit of time to just cool it down...

The time it takes you to stop at the gutter, shift into 1st, drive up the drive, park in the garage, and then undo your seat belt and find your wallet, phone and loose change is enough time to pull the plug on the motor. The turbo should have slowed down to a few thousand rpm at most my that time (Better than 100,000rpm or so at full song LOL!).

The information I was given ages ago while I was chaseing a water loss on the Landcruiser was that the Turbo can boil the water around it if not allowed to cool down properly. The water loss was found to be a cracked water jacket on the Turbo which was feeding water into the exhaust (after going to the trouble of doing the head up & not fixing the problem). How we found out was to block the water going in & out, run it for a couple of days, but don't spool the Turbo up too much. The problem is still there today & when I get home & go back into the garage after about 1/2 hour you can smell the coolant. The loss is about about 1/8 inch in the overflow bottle each time you use it. Water is cheaper than a new Turbo. The reason beween water cooled & non watercooled Turbo's is that some manufacturers believe that if you crack a housing on the water cooled ones you can feed water into the oil side with catastrophic results for both Turbo & engine.
