11-14 reliability compared to 15s

[bigaF250]

I know they haven't been out long but I have the chance to get a screaming deal on either truck. Price is obviously more on the 15 but if I'm spending that kind of money which is better. I know the 15 hasn't been out long enough to know the true life on them but what has been seen thus far?

I've seen good enough deals around here right now I'd just get a '15.

I would also just go with a '15.

Relibilty wise the 11-14's have been solid with exception of turbos, mostly.

My 11 went through 2.

The 15 has a "better turbo" supposed to be stronger. Plus Ford incorporated a functioning exhaust brake this time.

I would go for the 15.

Oh wait I did....

A true exhaust brake, like the Cummins' trucks?

 

[Powerstroked162]

It's a VGT actuated brake.

As stated above, they are using the variable vanes in the turbo to control the flow out the exhaust for exhaust braking. Cummins uses the same type of brake. As does the Duramax.

It does seem to work quite well though.

Theoretically the new turbo should be more reliable, as it eliminates the balance issues that the dual-compressor turbo had on the 11-14 models.

I guess the big question is what did they do to the HPFP system?

Hopefully the turbo proves to be better.

Fuel, not 100% sure, I will say my 2015 runs way harder than my 2011 did. But I am also at 6200 ft and go up from there so......

Ford claims the 15's have larger injectors and a larger pump. Anybody know the specs in comparison to the first generation 6.7's?

 

[morepower02]

I think that has been debunked but would like the official word on it.

 

[Mr.BigOil]

My Ford brochure is where I seen it. I hope it's not a lie.

Here are a couple pics I stole from SPE's thread they started in the aftermarket section on 15 turbos internals to the 11-14.
The 15 is on the left.
