Ford 2.7 Ecoboost - power question
This looks like a great engine at 325HP. That is about the same power as my trusty 5.9 Cummins ISB. On edit: If each engine is in a 1 ton chassis and matched to it's proper transmission and re...

Lots of theories here on what does what, but hook 10,000 lbs behind my 345 HP Duramax and 10,000 lbs behind your ecoboost, and I will stop and wait for you when I get up to the Eisenhower Tunnel at the top of the pass. I will drive the speed limit, and you will wish you could. Argue all you want, but I have never had a gasser pulling a trailer pass me going up the mountain. I don't "race" up the hill, I just follow the speed limits.
Nothing "magical" about diesel. A hp is a hp, and as per Issac Newton: speed is power divided by force (or velocity * force = power).
The only reason diesels are typically faster per horsepower is due to 2 things: 1) forced induction, no loss of hp at altitude, and 2) less than ideal real world transmissions, which favors fat torque curves.
Take away the 2 advantages, i.e. a turbo diesel and turbo gas hooked up to a electrical drivetrain (think locomotive), and a 365 hp diesel and 365 hp gas will perform IDENTICAL.
For that reason, locomotives NEVER officially rate their prime mover's torque. It's a useless figure.
