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...

I like high flat torque of a disesel for the ability to accelerate well throughout the rpm range. A "peaky" gas motor that makes low torque down low will also make low HP down low so it won't have HP available until you rev it up. Once a gas motor is rev'd up into it's powerband it has plenty of HP and torque available to keep your speed up the hill but you had better not fall out of that rpm range or it will suck. Nice to have 6,7,8 gears these days to keep her rev'd.
This pretty well sums it up for me.
Flattening the torque band into the lower rpms seems to be an advantage of a turbo in a gas engine as well.
Take a look at the torque curve on the new Cummins 800 ft lb motor. No longer flat and has a fairly sharp peak at about 1600 rpm.
