Most blower manifolds look like that on the inside. Length is not very important just no restriction to flow into the head.
Whipple is the best you can get for a positive displacement blower right now.
If you try to tune the length of the runner for a given RPM range, it would take a very long runner to help on a forced induction intake. The speed of sound is the deal, the pressure waves travel in the air at a certain speed and as pressure changes, so does the speed of the wave. A wave in the compressed air woucl require a runner that was very very long to work.

Keep in mind you're force feeding a blower motor, port velocity as it relates to a NA motor doesn't come into play under boost. Other than that intake bolting to the heads from the inside, it works. Take a look as some top fuel setups, you'll see the blowers and injector hats appear offset by a bunch.|

I am not an expert by any means but it would seem that the size of the runners would be more important that the length.

Intake runners and superchargers?
I'm trying to understand this... What roll do intake runners play in a supercharged engine? Take a look at this picture, its a Chevy intake manifold for a Whipple supercharger using a Carburetor.
It looks like it has almost no intake runners? Also the blower outlet sits at the extreme front of the manifold, wouldn't there be fuel distribution problems before the boost built up?
