And, on a completely different, and slightly more esoteric note ......
Plenum volume!

"...  The induction pulses in an intake cause velocity to rise and fall with
every pulse. The plenum helps to reduce them by acting as an air capacitor.
Average velocity will remain the same, but the highs and lows will be closer
together.  The induction pulses in an intake cause velocity to rise and fall

capacitor. Average velocity will remain the same, but the highs and lows

Do the lists have any particular insight into application of the above to,
oh say an AAN intake?
Any thoughts on how much of a change in volume would constitute a
"significant" event as re: the AAN intake manifold?  1cc, 10cc's a 100?

Anyone suspect they may be having any problems related to "Plenum Volume?"
