Driver mod > more power.
You need larger injectors to control fuel at higher RPM versus the same power at lower RPM. The injectors have to be able to deliver adequate fuel in a smaller timespan. I think that's what was being referenced.
The FPC with this high of displacement will likely present issues due to vibrations from a supercharger. Turbos shouldn't cause that issue as far as I can tell. Vibrations are going to be one area that we're just not going to know about until people start changing things. Ford apparently spent a LOT of time making sure that vibrations were down on this motor though. It wasn't too terribly easy from what I've read either.
Now, as far as piston speeds and rod length, I think you're overlooking a big part of the potential issue saying that this is "just a Coyote with a FPC". I basically agree with you in that description, but using a FPC completely changes things. You're comparing a FPC V8 that's pushing the limits of maximum functioning size to a CPC V8 that could easily go to almost double the displacement without any hat tricks. Piston speeds, and pressures acting on them at those speeds, are going to be apples to oranges with FPC and CPC V8s.
It's already been said a billion times that much of the factory hardware isn't going to be boost friendly, but to reiterate my biggest personal concerns:
Light weight rotating assembly including the crank itself (light weight meaning materials have been removed to make them lighter)
Low tension piston rings (I really don't get why this alone doesn't make people think twice about FI on this motor)
Hollow intake and sodium filled exhaust valves (not always a problem, but can definitely be with bigger FI power numbers)
Transmission built for high RPM NA power, smooth shifting, and light weight. It's not built for huge torque figures, so that may or may not be a bad thing (something besides the motor to think about)
You could custom build the engine if big FI numbers are what you want. At that point, it just seems silly to buy this particular car when you could make more safe power with a much cheaper one, and with less work.
It's been this way with every single major piece of tech that's come out. I remember when EEC-IV was going away and everyone was gnashing teeth and said it was the end of home tuning forever. I've largely stayed out of this because everyone already knows everything about this engine that hasn't really been on the street yet. I have little doubt it will be a race to get 1000HP from this thing - what the car is """"designed for"""" doesn't matter at all.I think that people are looking at this engine as an incredible complex and untouchable mystical creature.
It's just a coyote with a flat plane crank. Piston speeds are not much different than the coyote or road runner.

lol - well, hope they have a garage floor that oil cleans up easily from...Most people that are interested in doing this aren't going to want to break into the motor to put a meaningful amount of boost into it.
For sure - no doubt about that.I'm just saying that I'm skeptical of this engine handling much boost in stock guise.
