I can take my 6.6 liter LBZ Dmax and turn it up to 600 HP. Or I can just buy a 15 liter C15 with 600 HP.
This is a good example of what Ford is doing with the EcoBoost. They take a small engine and turn it up. Where as the big Cat can live all day at 600 HP the Dmax will not live very long at all at the 600 HP level.
The HUGE size of the C15 along with its cooling system can suck up and reject a lot of heat; the Dmax will melt down like a stick of butter in the Az sun at the 600 HP level.
Much like the example above the Ecoboost does not have a lot of duty cycle.
Bottom line is, it's easy to make HP with a turbocharger. It's extremely hard to deal with the heat it puts out. OP, you ran into both.
Except you are forgetting that Ford designed and built the Ecoboost to handle the power levels it's putting out just like the C15. The Dmax was not designed for those levels. All will happily run within their design specs.
