[Shop-talk] Premium for Turbos

Depends on the car and the turbo.

First, many turbos are water cooled.  They don't have any cool down 
problems.  Just shut the car down like a normal car.

Oil cooled turbo units, those can require a bit of a cool down, as well run 
synthetic oil, it doesn't coke up the way regular dino oil does.

As for heat up and spool up, it takes place in just a few seconds.  The 
turbo kicks in with boost just pulling away from a stop sign.  The harder 
you romp it, the higher the boost and the higher the heat.

Generally speaking, sane driving for a minute or two before shutting down 
will suffice with an oil cooled turbo.
