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 think the main things missing are these. A HP is a HP, no if and or but about it. However, how that HP is developed could differ wildly. Turbocharged motors produce HP earlier in the RPM curve, namely due to building boost and ingesting more air and fuel earlier (this is true with Diesels and Gasolines). This is why an Ecoboost which has less horsepower than a HEMI can pass that truck in a race, or when Top Gear did a 727 tow with a HEMI RAM versus Ecoboost Ford. HEMI makes more power ultimately, however the Ecoboost has a wider range of RPM where it's superior to the HEMI. The ecoboost always built more power earlier than the N/A motors, so they could get a leap on the competition. There is far more area under the horsepower curve of an ecoboost versus a 5.0 V8. They're rated at 5HP apart, however at 3,000rpm on the dyno plot @ pickuptrucks.com, there is a 50hp differential and only a 15hp differential of peak hp. Torque build is what effects that horsepower curve and that's what the engineers work with.
