in the plug itself the formers are there for shape, the glass on it is what makes up the strength.

and BVM are the worste ducts to be looking at since there for gas fans or slow running electrics fans. granted for gas stuff they were and are top notch! And since EVF mimicks a really fast gasser fan its also ideal. But for real velocity fast spinning fans they are way to short and bent, and the Y's end too short and should be right up as close to spinner as possible. And boundry layer at these speeds is ofcourse existant, but not nearly as thick as you'd expect, and frankly they do actually offer some relief from wet area drag.
