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.
