The EcoBUST engine MUST run in derated mode when not using BOOST.
An N/A DFI engine can have a compression above 12:1 even 14:1 in some cases (Mazda).
Whereas a BOOSTED DFI engine MUST be derated, ~10:1 CR, in cruise, off-boost mode.
Most engines run in cruise mode 98% of the time.
Ford's EcoBUST FE problem is compounded by the fact of the CAC collecting water and oil as an emulsion in the bottom of the CAC outflow endcap. Roll a perfectly good EcoBUST engine out of the factory door, within just a few miles engine components will begin to fail (bent connecting rods) due to (partial) hydro-locking.
Is it just me (cranky old guy) but this style of post makes me think - teenager?
In any case at least you can count out this source for accurate information regarding engines. There are many who contribute knowledgeable info on this board. The trick is to recognize the BS artists so you can ignore them.
