Man, 238 views and so few post. I find it hard to believe that with all the "which intake is best" discussions, no one wants to go the next step and find out which is really designed better and why?... odd

I would step in and add some stuff, but I'm way too busy at the moment to reply to any major tech discussion (too much stuff to review). But I'll jump in if I see a glaring error in thinking

In fluid flow, there is head loss and friction loss. Those are the two main losses. Head loss is from a size change, bend, or from another head of fluid joining the main one. (like 2 pipes coming into one)
In current flow, the whole cross sectional area of the wire is causing a friction loss. The friction in a wire causes the electrons to dramatically heat the wire.

Here is one that I found:
Choke Flow
I just skimmed thought it. And remembered about pressure wave, i wonder if that has anything to do with the whistling.
page 3, has a good diagram, explaining the increased velocity obtainable using orifices.
I hope this helps your search.
FYI - The only thing i did with my intake is put a Comptech Filter, and removed the baffle.
