Upper limits have not been proven on the 7.3 yet. There's Supercharged, and there's full tilt NA. No combination of the 2 yet. The Coyote uses boost much better than any factory 2 valve. The Coyote with a billet block has 4,000HP potential. I'm sure we'll see the limits of the 7.3 found within a year. You probably will never see the racing support for the 7.3 that the Coyote has.A built 7.3 made 789 hp naturally aspirated.
at end of the video they talk about the potential power of it when its boosted:
Running lean will cause detonation to the point of failure if pushed.Can someone with more knowledge tell me how the fuel became his issue? Even if he had more fuel, wouldn't the pistons still be a weak point prone to failure at that HP? In my mind, he would have needed built internals PLUS fuel to have prevented this? Again, my ignorance may be showing, just trying to improve.
