Alloy intake design.
Years ago, and still popular the works Audi Quattro intakes fed their plenum's from a rail which was connected to the boost plumbing.
Same sort of design is still used on some other very expensive top end intakes on 4cyl turbos cars too
ie, some good fabrication half way down
Just wonder why something like that never makes it's way into V8's ?
With the huge gap in the middle of the valley on say the HiRam, you could easily feed a central plenum feeding air upwards into the main plenum.
It should flow more evenly, and the intake would have a lower profile.
Of course...it may make **** all difference, but they look good lol

The main design advantage is not peak power, but more equal cylinder distribution, which mostly improved mid range power.
I think I did see pictures of this design on Audi v-8's or at least on v-6's.

I did seriously consider the twin plenum (per side) design, but when converting thought to reality it became too bulky.
Guess I would had to have called it a quad plenum.
As I mentioned too, using one of the cast alloy bases intended for ITB's as a starting point for a crossover would save a lot of work, and ensure a base that seals 100% on the heads.
It is just hard to imagine how all the effort and work, will really pay huge dividends in terms of actual performance.
The plastic 3d printed version and that carbon rendering for a crossover, the designs do look superb though.
The design is common on many high powered 4cyl engines too, with varying runner lengths. Some go long, some go short.
But even the factory intakes....just work damn well. That said, proper ITB's do work very well too, so maybe there can be a bit of both
