I think the stock turbo on the '15-'16 Powerstrokes has been proven reliable with after market tuning producing up to 580 rwhp. I believe Ford has increased the size of the turbo twice since then and we are only talking about providing enough air for about 400 rear wheel hp. Ford has made some significant changes to the 2020 engine in order to push the power to a new level. So although it's possible that they are just fudging numbers to claim best in class power it certainly is within reason to think this new engine will actually live up to its claims.

I thought we were talking about sustained 520 hp under high load(towing) with a Cat C13/15 versus a PSD?


My tuned with stock fuel and air could make well over 500hp at the wheels, but that does not mean it can sustain that amount of power under high load for very long. Neither can a supposedly 580 rwhp PSD. Also, as I said, I have not seen the compressor mapping of the new PSD to say for certain. There are also other factors that come into play when talking about sustainable EGT's at a certain power level like intake flow, intercooler efficiency, and exhaust flow.
While the turbo is the major piece of the puzzle, it is not the only piece.

Again, not saying that it isn't feasible that Ford may have addressed these issues to be able to sustain 475 hp, but it doesn't look like it from what I have read. I guess we will have to see the next Ike because the Ford should mop the floor with the Cummins with a 75 hp advantage.
