    Turbo cool down time

    I was talking to a dealer about turbo cool down after driving. The way I understand it is that a turbo car should have a cool down time/idle time after driven. Thats what the aftermarket timers do, right? The dealer told me that the WRX has gravity back flow of oil so that you don't have to let the car idle after driving. Is this dealer BS or what?

    General concensus is, if you have been driving hard, don't just pull in to a parking space and shut down the engine immediately. There is a thread somewhere in the forum on this:
    Turbo cool down
    This should help a little.

    I personally will be getting a turbo timer to use as a boost gauge with my MBC. Check out the Blitz DTT-DC.

    You're wasting gas. There is no cool down time needed.

    Let's say you drive your car at a minimum twice a day. If you followed the erroneously recommended 90 second cool off time, as previously mentioned, that would cost you 3minutes/day.....or 21 minutes/week......or 18 hours/year....or 52 days over a 70 year life span!!!! Stop wasting your life waiting for your subie's snail to "cool down"!!!!!

    Everything I have read indicates the turbo timers are a waste of money.

    If you were talking to a dealer about the 2011 WRXs, there is no need for cool down.

    They are water cooled after shutdown automatically.

    was this a merge or did an 8 year old thread just get resurrected?


    Older turbo'd cars only had oil piping. Newer turbos have oil + coolant. The coolant continues to flow after the car is turned off (until the t-stat closes)

    Unfortunately the worst part about the WRX's is the only way to properly cool the turbo is to drive to the fortress of solitutde.

    Half the folks that currently post weren't old enough to drive when this thread died.
