That sounds like a FUN project

The only thing I would wonder about is how quickly the "switching" affect could be accomplished. You figure that for an engine turning at 6k RPM, the intakes are going at 3k RPM = 50 cycles per second! That might exceed the mechanical capability of most pneumatic valves

It kind of touches off another thought though. At that high a pulse rate, I wonder if the inertia of the air flow mass exceeds the force required to cause a change in it's velocity (which makes a flow bench a more plausible approximation of reality). Guess I should dust of my Fluid Dynamics books!
