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.
Everybody has a right to their opinion, but to arbitrarily state one product or system is better than another, it needs to go a step further, posting some reliable data might help support your theory. IMO, your thoughts regarding runner length and velocity at "the speed of sound" and the wave thing aren't realistic or relevant for forced induction. I will agree, for NA motors, velocity is key; wave pulses? Maybe from rotor pulse or "push", certainly not something we count on for building power with forced induction.
