Turbo cool down time
I have heard a lot of controversy about the time you need to let the turbo cool down after driving. I have heard just let it idle for twenty seconds and I have heard five minutes. Is their a general rule of thumb like for every hour of driving let it cool down a certain number of minutes. Thanks

Turbo cool down time
Get a pyro gauge and let the temp get to 300 degrees or less then shut off.Depending on how you were driving and if you were towing it could take up to 10 minutes(from what I have heard) to get down that low.After normal driving around town to work etc it takes my truck anywhere from 5-20 seconds to reach 300 and I usually give it a few seconds longer to get a little cooler.This is so you wont burn the turbo bearings with hot oil,the cool oil circulates through the turbo and cools it down.Later Nick

Turbo cool down time
I've heard different temps to be safe for shut down. Mine is at 325* when I get in the driveway, regardless of how hard I've been driving, but I've modified my intake and exhaust to the max. I've heard that you can shut down at anything under 350*. With my truck, at 70 mph, I'm right on 600*, and when we turn off for a rest stop, I just turn off the cruise control at the beginning of the off-ramp, and let the deceleration cool things down. By the time we're stopped, I'm at 325*. By all means, get a pyrometer, so you know what's going on.
