"...EcoBoost develops its max torque at lower RPM..."
  
Well, yes, but ONLY when WOT or very close thereby.
 
Duh, that's the case for any engine. Your posts are comical.
 
The 5.4 v8 in my Expedition produces something like 365ft-lbs of torque at 3600rpm or so and it has pretty good off idle torque output. Trust me, when I'm towing my boat or travel trailer, I MUST FLOOR it to get max towing power whether at 2k rpm or 4k+.
 
Have you ever driven a DI turbo engine? I've driven a few 4cyl DI turbos and I've found the power to be very linear. I never needed to floor them to get power and it they were noticeably more powerful at part throttle and low rpm vs a n/a 4cyl and v6's I've driven.

Yes, lots of "magical-like" things can be done with/in the DBW firmware between the accelerator pedal position sensors and the throttle plate servomotor.
 
The accelerator pedal can have a perfectly linear "feel" while the throttle plate (and Turbo waste-gate) movement can be totally erratic, non-linear, in response.

That's all I care about is how well it works.
 
Ford is far from the only manufacturer using turbo charging with DI. You should be bashing VW, Mazda, BMW, Hyundai and others that use the same basic design. Turbocharging is not going away.
 
DI and high compression alone isn't going to produce usable torque like a much larger engine. Boost is currently the only way to do it.

Good luck convincing wwest of anything.
 
One of the benefits of two small turbos instead of one big one is that they spool up and generate boost more quickly - even at part throttle. Most of the critics of the 3.5 ecoboost engine have never experienced it.

The above link shows the torque curve of the ecoboost at part throttle and at WOT. It also shows the torque curves of some competitors.

Great post. Gotta love that torque curve even at...um part throttle.

I am a Retired 30 year Freightliner diesel mechanic. In those years I saw and had to learn the new technologies that would come out day in and out.Lets look at multiplexing for example.Who ever thought we could eliminate three quarters of the wires in a vehicle. And send signals over a twisted pair of wires?If we all believe in simplicity we should be starting our vehicles with hand cranks! I just purchased a new F-150 with ecoboost.I didn't buy a diesel due to cost and mileage issues.I have had it only two weeks but I love it so far!Lots of power!Very hard to believe that this is a 3.5 V6. TAKE A DRIVE

Taking a V-6 turning it to high-RPM's and thinking it is going to last is not very smart. The cost of ownership will be very interesting espicially when you start talking turbo failure or complete gernading the fragile high-tech motor.
 
The entire 'Green' agenda is the stupidest thing on planet earth, for starters oil is naturally occurring but people have been brainwashed into thinking mother earth is going to implode.
 
Heat, electronics and turbos what a great match up, with the Ford Triton's blowing out spark plugs I can't wait till these get out in the field and start racking up dollars in repairs.
 
I find it quite hypocritical Al Gore & Oboma the planet messiah's do not stop flying around in 'Corporate Jets', BIG SUV's and living lavishly.
 
I hope the numbnuts enjoy the Keynesian economic policies and their 'green' unemployment benefits.
 
Keep this fragile truck, make sure you got the pocket book to fix it. *If* anyone can find one running after 5 years, I am sure it will be a money pit.
 
A diesel is the ONLY sane approach, however the 'greenies' will not allow it. So they build this POS 'eco crap'.

Personally I'm holding out for the upcoming Otto/Atkinson/Miller multimode 2L I4, 16 base compression ratio.

The v6 EB develops more power at lower rpm than most most gas v8s. Peak HP is at 5,000rpm vs 5,500 for the 5.0v8. Max torque is available at 2,500rpm vs over 4k rpm for the 5.0 as well, so the idea the the EB has to scream at high rpm to make power is more BS.
 
Sure it's a more complicated engine so durability is a huge question mark. Considering how well the EB has been selling we'll learn fairly quick how it holds up.

"...the v6 EB develops more power at lower rp that most v8s...."
 
You make that up or did you find a factual, trustworthy, statement somewhere...?
 
~5000 RPM is NOT considered "low".
 
You neglected to mention the actual rating of V6's peak HP at 5,000 rpm vs the V8's at 5,500 rpm...?
 
Same thing with torque, need the actual numbers in order to judge fairly.
 
"...the idea that the EB has to scream at high rpm to make power is pure BS..."
 
NOT...!!
 
You can't quickly spool up those turboes without LOTS of exhaust gas flow into the turbine section. Plus you do not want BOOST at normal cruisng speed/rpm.
 
I'm not a fan of V8s by any means, but the gas-guzzling gas-hoggish EB is nothing more than a Ford marketing SCAM. I'll take a V6 with DFI and NO turbo, thank you. Maybe an SC if it's Miller cycle.
