But basically the cylinders get fed from the plenum, not from the intake point. So that is thermodynamically your starting point. The narrow end in your example doesnt point to that in its design basics. Also a wedge shape isnt necessary, maybe usefull to maximize use of space under the hood but for example on a modern turbo F1 car the intake is more of a box.

No sharp edges in the ones I've showed which should equal better flow and welded in pins so the plenum won't expand with high boost, the 2 pins on the plenum in the ad are close to the edge instead of in the middle of the large flat surface.
