Hey how about that.. I thought the Banana only ran once, at Richmond where Lorenzen blew a tire. Did not know it ran Atlanta too. Thanks for the pic Dave.
Jim.. great insight, thanks. The thing is though.. just looking at those cars like the 70 Torino Talladega and Dodge Daytona or even the cars until the early to mid 80s.. while they were definitely designed more and more to maximize airflow around the car, they still had so much front end clearance off the ground and only that little lip under the bumper. Seems like that while they understood the importance of cheating the air and basic effects of an inverted airfoil, they probably didn't quite know the advantages of creating a low pressure area under the car (think they call it the Venturi effect?? Not sure) by sealing off the front when at speed until the late-80s when the T-bird and the other cars started growing those big flared out front valances skipping along the ground at speed.
