I was talking to some guy about diesels and turbos and he told me that when you shut off your truck you should wait about 5 minutes for the turbo to get fully oiled and to slow down. i have never heard about this, is it a important thing to do or is does it even matter. i cant imagine it taking 5 minutes for the turbo to slow down. any thoughts?

 

Well i have heard about it before a turbo timer will increase the life of your turbo. 5 mins is a little long three max or until down to 300 degrees. Watch your pyro and you know when it is safe to shut off not when it is 550degrees.

 

I wait till 300 degrees. In my 12v, thats right away. In my 24v, it takes longer. Its so the oil doesn't breakdown due to heat and coke up the bearings.

 

i wait till my egt gauge says that its about 275 before i shut mine off.. and if i run it hard i might wait till it hits 250

 

Mine will never get down to 300. I have the timer set to 350.
