Louvers.....
In a trade journal on computer aided design a few years ago, there was an
article on air flow testing. One of the examples was louvers tested for a hot-
rod builder. It turned out the louvers like we have on our side panels was
the best design...flat on the outside. Louvers that were raised into the air-
flow created a pressure. Air was drawn in instead of out.
Another interesting subject was pick-up truck tailgates. Leave them closed
for best milage. A cushion of air circulates in the bed. The air stream over
the cab bounces off this rolling cushion. Leave the tail-gate open, and a
strong vacuum is created behind the cab reducing milage.
