I've seen full up sprints, both wing and non wing on a 5/10ths track. You'd be amazed. In fact the track had longer straights than the mini magic mile. It was the old Portsmouth grey clay track. Full up All star show that Keegan won. They hauled em in. backwards and shot down the other straight. Then I seen a NW practice on it. Same thing.

It was probably the wildest and non flatfooted winged racing I'd ever seen for Sprint Cars.
