Question on port matching

The best way to explain this to people is to have them imagine the open bed of a pickup truck traveling down the freeway at 70 miles per hour watching that loan piece of paper bounce in circles near the cab...never blowing out.
If fact you'd also see other bits moving from near the tailgate toward the cab and joining in with the paper in its backwash tumble....oh like a stream..with a dead flow spot where it widens off to one side.

318's with 360 4 brl intakes....

Re suspension...or vorticies/back washing whirlpools.
