After reading all of this, I think it is time for me to put my .02¢ worth in.
I am not an automotive guru, but my understanding is that the major part of making power in an engine, is to reduce the drag of pulling air into the cylinders as much as possible. the reason that I understand that you want to do this is because when your intake valves close off, you haven't pulled all of the available air into the cylinder, because of the vacuum that us created by the drag from the pistons pulling a large amount of air through a small opening. therefore, you are never able to fully fill your cylinders with their complete volume of air (there will always be vacuum in the cylinders before the piston begins to travel up again).
so the remedy to this is (in my understanding) to increase the size of your valves (and their lift), ports, intake runners, (and yes) throttle body. the enlarging of one without the proportionate enlarging of the others will only gain as much as the most restrictive part of the intake remaining. I think that the throttle body is probably the least of all of these, but I imagine that it would become more important if all of the other factors were improved.

I also am of the opinion that like an exhaust system, the factor of velocity being able to (scavenge) the exhaust out of your cylinders at lower rpms with a somewhat restrictive exhaust, is a trade-off for the restriction that is created at higher rpms. likewise the scavenging effect that the intake velocity has to push air into the cylinders at lower rpms with a somewhat restrictive intake, is offset by the restriction that is caused at higher rpms, where a much larger flow of air is needed.

none of this takes into account the possible affects the a less turbulent flow might have on the fuels ability to atomize properly and burn efficiently when mixed with the incoming air.

or maybe I have been drinking WAY too much coffee again.
