Re: Turbo care


I've owned 2 Audi turbo's, both oil-cooled.  The first, an '82 5KT, was on
its 4th turbo when I sold it at @115K miles.  I made no effort to cool it
off properly, and had some bad luck (a turbo shaft broke in 2 pieces in the
middle of the night with a car full of wife and kids, but that's another
story.  Kept driving till the noise went away.).  My current '83 urQ has
close to 100K miles, with no signs of turbo fatigue.  When I had my heads
done a couple years ago, the turbo was checked for free play and passed
with flying colors.

The difference?  I learned the hard way to cool it down by idling at least
one minute after anything more than a 3 minute run.  I also switched to
Syntec when I got the car about 6 years ago.  Combined with a measure of
decent luck, it still runs fine.

Should work fine.

I'm fairly sure it is, but someone else will know for sure.

Nice idea, but probably overkill with water-cooling and synthetic oil.

>Turbo timer for cooldown?

Also nice idea, but not for a car with a stick.  I always use my handbrake,
but I always leave it in gear as well.  Belts and suspenders etc...
