The 2017 Eco-Boost vs V8 Bench Racing / Whining thread

[WyoStorm]

Somewhat agreed - they are putting the 3.5L Eco in the Transit Vans, clear up to the 1 ton rated vans....surprised the F250 doesn't have a 3.5L Eco option...checked tow ratio's on 3.73 4x4 and the
F150 max - 17,100 GCVR and 11,800 max trailer
F250 6.2L - 19,200 GCVR and 15,500 trailer

Unless they figured putting it thru the paces in the 1 ton vans would give them the data/backing for the F250...also surprised it seems they de-tuned the vans so much -
Van - 310 HP @ 5500 and 400 @ 2500
150 - 365 HP @ 5000 and 420 @ 2500

The only difference I can see is the Van's stroke is 0.04 in. less than the F150 and DAMB vs DOHC on the valves....makes me wonder how much more one can open up the vans with a tune...

Maybe they also figured the F250 market would be harder to break into with a V6....look at all the stir just in this forum for a Raptor...

Maybe the gen2,will be the test bed for the 2018 or,2019 super duty motor.

An issue I could see with the 250 is weight and its impact on mpg. The eco would have no trouble power wise but because the weight range is 59xx-76xxlbs, most variants would cause the eco to be in boost more often than the 59xx-65xx f150 range resulting in worse than 6.2 mpg (7.0l effective displacement @ 14psi).

The F150s have shown that the eco is VERY sensitive to weight changes WRT mpg. Plenty of power though.

We have a new Expedition with the Eco and love it.

Good call on the weight. I know they're moving the 2017 Super Duty to aluminum like the F-150s. But I don't think a 500-700lb difference will be enough to keep it out of boost.

And Ford already said that about half of that weight savings went right back into the vehicle for a stronger frame, larger axles, heavier duty driveline, bigger brakes and a better transfer case. I believe the number I read after all that was maybe 350lbs less.

I farm need power so yes would be in boost all the time. We pull way more that it's rated for in the fields

Ahh, I didn't see that from Ford. Thanks for the clarification.

Agree with the weight comment, but the van's will really put it to the test. I use to have HVAC service vans and us service guys that traveled out to the boonies would carry a lot of weight. Granted pretty rare we towed, but consistently carrying the weight.

Towing my Eco was 7-8 mpg, but that was also running 75 mph, but a smaller single axle 8x10 enclosed trailer. With it empty might get 10.

Did anyone watch the episode of Jay Leno's Garage where they featured the new GT? Raj Nair made a comment that they went the 3.5 Ecoboost in order to showcase the technology. Just goes to show that it's all a marketing scheme. Too much money invested in the ecoboost platform.

It was also about returning to Le Mans in the LM GTE Pro class which restricts turbo motors to 6 cylinders.

@Rookie that's the only reason I can think for putting it in the gen2 Raptor but still have the the 6.2 (and bigger motors) available in the 2017 Super Duty trucks. Still doesn't make any sense to me in a Raptor. I guess the Raptor is the guinea pig for the new eco that will then go in the Super Dutys in a year or two?
