Aerodynamic Fuel Economy Savers for Road Vehicles
i think i may get some and put them on the ford ..
maybe some on the MG hard top too.. but for the MG gonna wait until i run in some rain and see how it *flows*
the black thing on the ford aft top was bought 15 years ago.. . sure does help blow dirt on the back when on dusty roads..
theory is that it directs smooth air from top side to fill *the Vacuum * of the big hole i punch in the air.. thus reducing drag.. maybe works maybe not ..but it sure does change the air flow after the block..
there are many of us started down this long lonely dusty road 50 years or more ago...
Whats your evaluation of that old top duct on the ford ??
