Hi, John.
Velocity stacks are the trumpet shaped intake pipes that you sometimes
see on race vehicles.  (Sometimes you don't see them because they are
carefully hidden under bodywork.)  They provide a smooth transition
from the non-moving air on the outside to the hegh-velocity air that
has to travel into the intake system.  Gotta run, but if you still
need a picture, I'll try to point one out when I get back.
