Default Does anyone else feel this is Doo Doo?

I pulled this quote from the Vancouver I-Club forum. Not sure if there's any truth to this or if it's Canada's evil plot to kill the turbo's of our '02 WRX's

quote:
--------------------------------------------------------------------------------
Thank you for your inquiry regarding cooling down the turbo engine in our WRX models. Our position regarding this is that it is not necessary to perform a 'cool down/idling' procedure, as was recommended with past turbo models. Our current turbo engine has far greater cooling capacity and coupled with technological advances, makes this practice no longer necessary. This explains why information about a cool down is not included in the Owner's Manual.
To further explain, the heat contained in the turbo charger will begin to vaporize the coolant in the turbo charger after the engine is stopped. The hot vapor will enter the coolant reservoir tank, which is the highest point of the coolant system. At the same time that the vapor exits that turbo charger, coolant supplied from the right bank cylinder head flows in to the charger. This action cools the turbo charger down. This process will continue until the vaporizing action in the turbo charger has stopped or cooled down.

I, personally, am still going to run my WRX for a few before shutdown.

I let my car idle for a little too. If not for actual benefits, maybe just for psychological comfort

No because running coolant through there does keep the temp down and below the temperature potential of coking the bearings. Remember the turbo can get up to 500+deg (Celcius) easily and regular oil begins to break down at @300deg synthetic has a slightly higher tolerance @400deg. With synthetic and the coolant running through the center section it helps to keep the bearings from coaking with oil if you shut the car off after a hard run as the temp stays lower thanks to the engine coolant running through a nicely sized front radiator. It's mainly extra peace of mind to run a turbo timer or time it your self as it doesn't hurt.

Default Cool down?

Do the words "turbo" and "timer" mean anything? I mean, i'm no xpert, but it seems like the best method if you can come up with the $$$. (unless you are obsessed with your car)

Only if your too lazy to do it yourself but this is also why the watercooled center section of most all modern turbos is meant to be used is to keep the turbo bearings from "cooking" the oil and clogging the bearings. Unless you are doing some serious thrashing "timing" isn't exactly necessary but like it was mentioned above is more of a "peace of mind" doing. Now if they didn't have the center bearings water cooled then YES TURBO TIME!!! I think as long as you use synthetic oil (good quality) and the turbo center bearing is water cooled then you shouldn't have a necessity to turbo time it as both the oil and the water cooling will help to keep the temperature from getting too high and coaking them.
