Sufficient air is frequently supplied by a 3" hose that forces outside air from the front of the car into the interior of the rotor. That air then flows through the rotor's vanes and exhausts quite a bit of the heat that's built-up in the rotor.

I'm not seeing anything concerning funneling air to the rotor center hub area for increased air flow through the disk. It seems that increased air around the outer circumference draws the air through. Now funneling air to the hub or caliper for cooling may be beneficial for those particular components.
I'm questioning whether increased air flow to the rotor center hub area actually causes turbulence and minimizes hot air drawn out through the outer vents. But, I haven't read the above closely enough to be certain.
