F - Series Super Duty to get a larger turbo

Just read that the 2015, yes 2015 ugh, Ford Super Duty will have a larger turbo. No mention of projected torque/HP but my guess is they want to leap frog the Ram with 850 ft lbs. of torque.

Not sure how far they can push these trucks. What do I know? Seems to me the Ram 3500 DRW towing a 30,000lb trailer is too far.

They really need that SAE towing test to kick in to standardized any towing claims.

Also no mention of frame improvments or brake impovements...so far only the larger turbo. I imagine the frame and brakes will need improved, again to leap frog the Ram.

from what I have read they are also planning alot with aluminum especially with the smaller trucks like alum frames and body panels. The cafe standards are not letting up.

Or is the larger turbo to help resolve turbo issues on the Ford 6.7L engine since it is buried in the valley of the engine? Google the issue and see all of the hits on this complaint.

I have a problem with a company that in this day and age could have built an engine that spits out spark plugs. I just don't trust their engineering skills.
Just my 8am rant, sorry!

Jim W,
That was mostly an issue on the C&C trucks with a different turbo. But the pickup turbos just didn't produce like everyone wanted them to. Being buried doesn't hurt a thing.

Jim W,
The turbo position really is not that different than that on a Duramax. I did google it and most of the few pages were nothing more than some questions, general 6.7 talk and 3 failure questions. The larger turbo is to help with a HP and torque increase and to fix the low engine braking that the current 6.7L have. Google is no where near as accurate of a source than the actual warranty numbers. And there are very few issues with the turbo.

A turbo is most effective if it can bask in the heat. Helps with spool up. That's why the intercooler is in place, cools down that hot air.

A larger turbo means more mass and inertia, so spool up time will suffer.

Very true. It looks like they changed the torque converter to mask this. Ford claims you will be hard pressed to notice a difference in take off compared to the 11 and 12 models.

Why do you say being buried doesn't hurt a thing?

How does the turbo cool after the engine is shut off? No air movement or fluid being pumped to cool the turbo. Or is it OK to be baked like a cake in the oven?

When I was at Cat the engine team would go nuts with the vehicle design team when we requested to wrap a turbo due to heating issues with surrounding components. They wanted that turbo to be exposed to air for cooling after the engine was shut down. Oh will I guess it is OK since Ford designs it this way.

The turbo is not only cooled by engine oil, but also cooled by the primary cooling system. There are multiple sources of cooling for these turbos. As always, if your running it hard, there should be some engine idle cool down period. Im sure Honeywell has some say when it comes to turbo cooling since they are footing the bill for turbo failures.

Not sure about their diesels but Ford uses siphon cooling on the ecoboost engine turbos,I would bet they got the easy stuff covered after all they aint totally stupid

We are discussing the diesel turbo location not the gas engine model location.

That maybe true and most experience user do know to let the engine and turbo cool down before shutting the engine off. But with the design of the new 6.7L ford engine and the turbo buried in the valley the turbo will not cool with ambient air since the engine is heat soak. This heat will transfer to the surrounding components and to me this is what will cook the oil and water that is in the turbo as it sits there. Also are you sure that Honeywell is paying the warranty dollars and not ford.
