for what it's worth: my shaker setup flows a sufficient amount of air to enable the 7.0 liter to make ~490hp to the wheels (about 540 crank).
I'd take a look at MAP sensor readings before arbitrarily bashing NA induction systems.

Wish they were, I hate the old, and new Hellcat hood. Only thing about the car I do not like is the hoods. I am old school though and like the "Power bulge" on the 2015-2018's I guess if I was getting a new 1320 Scat or Scat I could get used to the old SRT hood (the one that looks like an AAR Hood) or order a the older Power Bulge hood.

The misconception is that the shaker is somehow "force feeding" air into the engine. This is absolutely not true. And if you think FCA actually designed the shaker around wind tunnel testing to bring the functionality of the shaker up to that level, then I couldn't laugh more.

Just because the shaker is sipping on outside air doesn't mean it's the same as a ram air effect, which has been mentioned and argued on this forum throughout the years. The shaker isn't forcing any more air into the engine than a non-shaker car would. If you think that's worth the price from a performance perspective, good luck. The only thing that makes it worth the price in my opinion is the looks factor.

And efficient and functional go hand in hand. Efficiency is a performance measure of the functionality. The shaker may technically be "functional" since it's baby bottle feeding on air around the hood rather than in the engine bay, but it's not very efficient compared to other functional systems.

But it is technically functional none the less, and any arguing beyond this point becomes pointless semantics.

I'm amazed that no one has yet to mention the fact that the top of the Shaker airbox is wide open and does NOT seal to the hood, so it's drawing hot air in from the engine compartment. Also, the opening at the bottom is open to the fenderwell just like all the other cars.

On mine I'm looking at setting up a tube to feed the bottom of the airbox from the passenger side headlight and also looking at sealing off the top so that the only path for air to get into the airbox is from an outside source.

It is completely functional and does exactly what it was designed to do: It was designed to separate people from more of their money and functions quite well at that.

Air passes through the Shaker scoop and goes to the intake, so it's obviously functional.
