*26.73 mpg compared to 19.0 mpg is a 40.68% increase.
*If we guestimate 5.5% delta-mpg per 10% delta-Cd @ 65-mph,we're looking at a 73.97% drag reduction necessary to explain the higher mpg.
*With a 73.97% drag reduction,only 26.03% of the original drag remains,or,Cd 0.1145 is suggested.
*Sure would be interesting to get Dark Shadow into a wind tunnel.Or at least an accurate scale model.
*(hey Texas A&M University,what'd'ya'think?)
