I've been trying to find some cool pics of todays Top Fuel cars. I forget what they are called but when the dragsters are "cutting" through the humidified air with lots of water molecules, the rear top wing creates a little "turbulence" and you can see it off the tips. I forget what that is called. But I've been trying find some pics or {hopefully} posters of that happening. Do any of guys have an idea what I'm talking about??? Mike Dunn explained it during one of the races last summer. I believe it may have been Denver.. I've been looking ever since.
