Bear with me, I'm not an engineer (but I do spend a lot of time
watching the Discovery Channel).
The dimples on a golf ball trap air. As the golf ball flies through
the air, it rolls "forward" in the air. The pockets of air move
forward (the direction of flight) and down (toward the ground).
This creates an area of high pressure *under* the ball and an area of
*low* pressure above the ball. The spinning ball generates its own
lift. Kinda like the wings on a plane.
This principle would be tough to transition to the intake manifold
world.
