The Joe James/Pat Oconnor show at Salem paired USAC and Must See Racing on the same track, same night. In qualifying the wing fast time was a little more than a second faster than the non wing car. The wing car was faster in the corner, but the non wing car was quicker from the flagstand to its shut off point, which was a bit earlier than the wing car for obvious reasons.

At any speedway there are a variety of factors that will determine the benefit of a wing. To use a minisprint with its low power to weight ratio compared to a 410 sprint car in a drag racing or absolute speed contest, the non wing car should be faster, unless the wing is trimmed to reduce the downforce it is used for. That is the case until the general shape of the car itself begins producing lift, something that will happen at speed much higher than you should ever propel a mini sprint. This is what the Sprint and Silver Crown cars battled at places like Gateway years ago, and "necessitated" the next generation Silver Crown cars.
