The beauty of the EcoBoost engine is direct injection not the turbo. Turbos have been around for a very long time and their issue has always been pre-detonation at high boost. Since the direct injection does not put fuel into the cylinder until it is time for the fuel to burn (just like a diesel) there is no fuel to pre-detonate on the compression stroke. The EcoBoost does not necessarily have to stay out of the boost to be efficient. The EcoBoost can simply run on a non-stoich mixture because of the direct injection. This is their ultra lean burn mode!
As long as the engine is designed to take the high compression... (without popping a plug! FORD!!!)... the service life of the engine should have a sufficient life span.
I think the direct injection on the EcoBoost is a big step forwards. Do the Chevy and Dodge cylinder dropping engines use direct injection? I do not believe they do (feel free to correct me) so to me they are not nearly advanced as the Ford and don't have near the future potential.
At what RPM does the 2.7 develop 325hp? What is the torque band of the 2.7 like? 325hp and 87ftlbs of torque at 7000rpm?
P.S. I wonder what Ford could do with a small block direct injected EcoBoost V8 in a 3/4 ton or 1 ton pickup? Hmmmm.....
