I've heard that too. I probably don't keep that in mind all the time
but I also am rarely in a big rush so it would be left to idle for
a while before I shut it down. I assume the turbo is spinning all
the time. Too bad it couldn't be set up to only turn on when extra
power is required, then I'd almost never use it. I drive pretty
sedately for one who was into muscle cars in my misspent youth..  B)

Okay.. I had a look online and found various info on Turbo speeds
and in general most turbos spin very slowly at low RPM's, say
1000 rpm at idle compared to up to 200,000 rpm when pushed..

But, that said, I looked it up for my specific car and it said
that the turbo does not spin at all unless you put the engine
under the stress of high acceleration or when pulling a heavy
load, which might be why the lifespan on that model is usually
quite long.
