There used to be a guy here in Colorado in the 1970's with a 1953 Studebaker powered by a 426 Chrysler engine, the cars name was Taboo.
He was running 11.34 at this altitude, and was a hoot to watch, because on the top end his aero advantage would allow him to run people down. It looked like he was suddenly accelerating the last 330' but it was really the other car started to slow down a lot more than he did as their speeds got over 100 mph.
Aero helps drag cars but mostly over the last few hundred feet. If your a lower drag body, you will continue to accelerate when cars with poorer aerodynamics start to slow down with the same power level due to their higher drag as the approach the traps.
