Turbo cool?

ajandhek · 07-12-2013, 09:54 PM

How many of you let the turbo cool after some hard driving?

Maybe if it's very hard driving, but I never do. I don't think you need to on these newer Turbo cars.

I believe the cooling system continues to cool the turbo even after you shut off the car.

+1 This is true

Its not the cooling system that matters when leaving the turbo to cool, its the fact that the oil circulation stops immediately and you end up with the turbo bearing temps rising because of no oil feed and cooking what oil is left there. In day to day use I don't bother letting it run on idle for a little while but I always have a mile of so of gentle driving before stopping. If I was on the motorway though or pushing hard and then stopping I would give it 30 seconds or so for the temps to level out before turning off.

I believe both the oil and coolant continues to circulate thru the turbo even after the car is shut off.

There is only an auxiliary water pump, the oil pump on all the engines I looked at were chain driven and there's no aux oil pump.

Thank you for clearing that up.
