2015 Navigator EcoBoost has +15hp and +40ft/lbs more than F150
 

Wow, the 2015 EB Nav is rated at 380hp and 460 ft/lbs of torque. +15/40 more than the 2015 F150 and Expedition.


I'm waiting on another Expedition, a 2015 Platinum model this time, I'd be pissed if there was a power upgrade mid year. Anyone know if the Nav uses any different hard parts, I suspect the increase is all tune. If so, Ford should offer the tune for sale, I'd be in for ~$2-300.

Interesting, 150+ views and zero comments. I see threads here going upside down with HP and torque on the 6.2 / 5.0 / new 2.7 motors and no one gives a **** that Ford gives their smallest market, the Navigator, a significant
advantage over their best seller the F150 (and to lesser degree the Expledition). If I were a new F150 buyer ( or expedition buyer like me) I'd be pissed, but that's just me...

The reason the others are not responding is the fact that all 3.5 Ecoboost engines will provide 380hp with Premium Fuel.
The Expedition has the same motor, but it requires Premium Fuel to reach those higher numbers.
The devil is in the details.:-X19

That's one part of the issue. The other is the fact that Ford hasn't released the numbers yet for the 3.5 egobooster in the '15 F150 or the '15 Expy yet. They could be more or they could be the same as the current '11-'14 trucks. Nor did Ford release any info as to whether or not any components on these engines will be different between models. So if Ford hasn't released that info then no one else can say either way if there will be any differences. So we all have to be patient and wait and see. No need to get upset that no one has yet responded, or accuse anyone of not giving a ****.

Hi,

Too me it sounds similar to the 6.2 in the F150 and SD line ups. The 6.2 in the raptor is using a couple of different parts and premium fuel to achieve the numbers but it is also the "hotter" motor of both. From all the readings I have seen, the common knowledge is the 6.2 in the SD was detuned slightly for durability. The 3.5 in the F150 (and now in the expy) might be "detuned" for the lack of a better word for longevity purposes. Most likely reason is the truck will be used in a fleet or working environment in which regular gas (fleet fuel cards) is being used. The Lincoln Navigator is likely going to be in an environment which towing and/or hauling bulk material is not a concern. Therefore, you can make the motor "hotter" knowing the customer is likely going to buy the more expensive fuel to. Chances are those same Navigators may be turned in after 2-4 years on leases as well.

Ford.com shows 365/420 for the 2015 Expedition and F150.
Thanks

when I ordered my truck today they gave me the options paperwork and this was in it.

If I'm not mistaken, I thought I heard a while back that the 3.5 egobooster and the 5.0 were slightly reworked. But if that is true Ford is being very tight lipped as to what has been reworked and what the power output will be. And that was about the time of when they first announced that there was going to be a second generation ecoboost. Now I'm beginning to think that may in fact be true given you paperwork.

More power would be even better.

Ok the Lincoln site now shows a "*" next to the 380/460 numbers indicating premium fuel.

Is the current EB smart enough to advance timing and fuel (just shy of the knock sensors) to generate more power based on octane?

Thanks

I heard somewhere (probably on FTE) that the Ecoboost recalibrates itself every time you fill it up. It can take into account premium fuel, ethanol fuel and probably other things. In essence, it's constantly relearning it's timing and fueling maps.

Yes. Guys that do data logging/tuning have reported the ecoboost has an advanced knock sensing setup. It continuously adjusts timing and will, interestingly, even allow some knock as it sees fit. (Which, truth be told, scared the crap out of guys who weren't familiar with tuning these engines.)

It wouldn't surprise me one bit if nothing was changed between the Navigator Ecoboost and the F150 ecoboost, other than the premium fuel rating.

I know there is a definite difference running premium as opposed to regular.

Is there less Turbo lag and smoother acceleration? I am trading a 2007 5.7 Tundra and the 3.5 Eco is kind of disappointing..

Sounds like you should get another yoda?
