OK, I HAVE to finally ask this burning question that I've had for a while (actually, I guess it's more of a musing, than a real question) -
I keep hearing about the 30-second idle to cool the turbo, and I don't see how pulling into my garage and idling would be helping to cool the turbo any more than simply driving the car, off the turbo, for the same amount of time or longer. (how's that for a long sentence?) Do people really get off the freeway and immediately shut the engine down and screach to a halt in their driveway? Personally, I exit the freeway where I may or may not have been on the turbo, cruise along through my neighborhood at about 25mph, and eventually park about three minutes after any chance of being on the turbo. And I live pretty darn close to the freeway. Or maybe others are on the turbo around town more than I am?
Just wondering if driving around slowly counts for my turbo-cooling time. Seems a waste of gas and time to idle after putting along city streets.
Here's how hot the turbo can get when run wide-open for 24 hours.
Probably don't do this for the first 1000 miles
