when throttle is open, the entire tract from free air to valve is a resonating tube.


good point, but it would only stand for long bellmouths (like the red). the taper of the belmouth would have weired effects on the resonance too.

plus, being an open end, rather than a wall, means youre dealing with a switch from fixed boundary harmonics, to open pipe harmonics - and that sucks! where is the transition?

but yeah, my original comment was direct at small height bellmouths with a rapid exponential curve.
