<VV> Highrise air cleaner

Air has inertia and at high velocities (WOT) it gets turbulent particularly 
around corners and you don't want that to happen in the carb throat area 
since the signals are taken from small passages. Having a couple of inches 
of straight throat (velocity stacks) above the carb smooths the airflow.

Keep in mind that the air velocity in the intake is usually greater than 
the car velocity (Have been sonic carbs patented though operation at 
"choked flow" is usually not a good thing).
