Ecoboost vs. V8 - Can you explain?
I'm nowhere near being a gearhead, and I can't seem to wrap my mind around how the Ecoboost outperforms the V8 in towing. I understand the fuel economy issue, but how is it that the V6 can actually h...

I haven't ever had an engine with a turbo so I'd like to know how they work. First of all that's a very impressive torque curve for the Eco Boost. I wish my 6.2 had one like that. When it's running 2,000 rpms would the amount of torque shown be with the turbo running? Does the turbo start running at a certain rpm or at a certain level of throttle position? If the turbo isn't running at 2,000 rpms would the torque be less?
Just wanting to understand a little more.
Yes, the amount shown is with the turbo running. The turbos start to spool at a very low rpm and I am not sure you could even get the truck to shift into an rpm they can't build boost at. Under normal acceleration, you will start to build boost as low as 1,200 rpm. They are mainly low to mid rpm turbos and loose their breath at higher rpms past 4,500. This is good for quick responsiveness while towing and normal driving, but not so much on the drag strip.
If you push the pedal to the floor there is a little turbo lag, but I would be surprised if it was longer than a second.
