turbo cool-down question
Since I don't have one of them new fangaled thing-a-mabob cool down timers how long should I let the turbo cool down,say, after a two hour freeway drive? After a 10 minute drive down to the pet therapists office(emotionally disturbed shih-tzu)?

The only time I have ever let my car idle is when racing . . .
and by that I mean on the track or at an auto-x.
Driving every day I have not let my car cool down. Generally you don't go from a high speed to a stop, so the finaly few minutes of driving at a slower speed is more than sufficient.
Let me give you a little example as to why I don't have a problem with this. The majority of the turbocharged cars sold in the world today and not sold to enthusiasts, they are sold to your average everyday person. They are not the kind of people that would stand to have to sit in their cars while it idles for 1-3 minutes. They want to drive to where they are going, park and get out.
My sister had a Volvo Wagen with a turbo in it. She was the second owner and knew the first. She got the car with 150,000 on the odo. She sold the car a little more than 100,000 miles later, still on the same turbo. She never once let the car idle and neither did the previous owner.
I am just over 40,000 on my TTQ and never let it idle except as noted above. Will idling allow the turbo to live longer? Maybe, nobody knows for certain. It is really up to you. But the turbos in our cars are both water and oil cooled.

Yeah, but with a service interval of 5K - 10K...
<b>Maybe</b> you can get away with it...
Then again, I've religiously done a cool-down with all my turbocharged cars. Everyone swore that a turbo in an '89 Ford Probe GT would last 60K, 70K tops.
Cool downs and oil changes every 3K and my turbo was still going 100% with no problems at 128K when I sold it...
