Turbo Cool Down
I'm about to take delivery of my 2011 350 with 6.7L diesel. The finance guy said that it would be worth adding something to the remote start that actually keeps the engine running, for a short time, after I turn the ignition off and remove the key. This would give the turbo time to spin down. I"m brand new to diesels and turbos, does this sound plausable? If so, is it recommended? Thanks.
I'm getting my truck in the next day or two.

Turbos do need time to cool down, i dont think the new 6.7 need that though, but im not sure.

its actually a really nice kit, you should look into installing it. it is actually set on a pyrometer probe so when your egt's are still hot at the turbo, it will idle the truck to let it cool down. it prevents the oil thats on the turbo bearings from boiling. every turbo would benefit from this. if the turbo isnt hot then it will shut down when you turn the key off. its great if you run your engine like a truck should be run, or when you start to add performance items like exhaust, injectors, programmer. more power = more heat.

10 turbos would get hot. it still has hot exhaust flowing through it. you always wanna let them cool down, especially if your pulling a trailer or wheelin it. 180 bucks is pretty cheap insurance to add life to your 2 turbos (2 turbos to rebuild as well)

Thanks
Thanks for the replies and the information. I will be pulling a fairly heavy load but it will be fairly infrequently (4-6 times a month in the summer and almost not a all in the winter).
I'm going to look into it and talk to the service advisor at the dealership.

There is only one turbo, but it has two compressor wheels just for clairfication.

Dont install the cool down timer unless they give you the ok, there is also a cooldown timer that reads the temp from the turbo and shuts the truck off when the turbo is at the coolest temp, sometimes a minute isnt long enough, especially after pulling a trailer.

that is exactly what we are talking about. There's a probe that gets installed after the turbo in the downpipe and reads the turbo temp egt's.

Is the probe already there as part of the turbo or is in stalled as part of the BD Cool Down Timer?

you install your own probe (that comes with most timers) some piggy back off another probe if you gave an aftermarket installed already. I don't suggest that through, as probed should ALWAYS be matched with the gauge or unit.
