You have a tough time marketing 510 rwhp on a car that starts with 415 advertised hp.. It is all about perception. People don't think of the 5.0 mustang as having 350 rwhp, they think of it as having 415. You have to put the numbers where people will recognize them.
It doesn't help that you can get 460-480 rwhp wth the "old technology" 4.6. The perception is that the 5.0 has 100 more hp than the 4.6, so any mods have to follow that perception by showing a 100hp difference for the same money. So if you can get 550 crank horsepower from the 4.6, you should be able to show that you can get 650 crank horsepower from the 5.0 at the least. In reality, the high compression ratio isn't going to allow for it on a stock 5.0 motor, and that compounds the problem.
People who like to mod cars need a reason to get the 5.0. So far, the best reason to get it is because it doesn't need any modding to be a great performer, and that excludes the mod market.
Don't expect anyone to be advertising rwhp differences with the 5.0 anytime soon.. at least until after the memory of near 100% gains in hp from a modded 4.6 are long gone.

Very well said.
Exactly what I have been thinking every since the 5.0's official stats were put out.
Except for at first... I was one of those wondering about the F.I. at all.

Keep in mind the 5.0 is making 100 hp more to BEGIN with from only .4 liters more. That's a huge gain in and of itself.
100 hp more usually requires a full liter of displacement more to make that kind of power gain. Consider the LS2 to LS3, it went up .2 liters but only made 26 hp more (36 with performance exhaust added). It would have needed to make 50 hp more than the LS2 to increase the same amount of power as the 5.0 did per liter over the 4.6.
So think of the 5.0 as a larger engine that has additional mods on it from the factory.
As for the boost and CR, it's mostly all relative. S/C is just pressurizing the air for combustion. High CR from the factory pretty much does the same thing. So whether you have 9:1 compression ratio and 10 lbs of boost or 11:1 compression ratio and 7 lbs of boost, you'll be making essentially the same power.
Every engine can only take so much forced pressure into it, whether it comes from CR or from boost, at some point it will be maximized.
Like you said above, lots of it is just perception, as having "only" 7 lbs of boost doesn't sound like a lot or impressive next to a car that has 10 lbs of boost. But you have to consider overall pressure, and most don't look at CR they think "more boost = more power" and don't consider that the car with less boost and more CR may in fact be making more power.
Plus I'd take 550 hp from the 5.0 any day over 550 hp from the 4.6
as it take a lot more (either boost or mods) on the 4.6 than it does to make the same power on the 5.0
And it's the quality of power too, peak numbers are just that, numbers at a very small range in the power band.
I for one will still advertise my rwhp gains when I dyno my mods to my 5.0
It's the only numbers that can be stated as fact and without guesstimating if an engine dyno isn't used.
