Most of your shots are static, try and convey motion and energy in your photographs. For burn-out shots move a little bit to the side, shoot a little slower, and get the motion of the tire in the shot as well as the smoke wrapping around the wheel. Move into the stands at about the 60' blocks or farther, slow the shutter down to about 1/100 second, and pan with the cars as they pass.
Look at the intensity in the eyes of the girl driving the dragster in shot #6, perfectly framed by the roll cage. There's a photograph.
I like the first shot since it shows the expanse of track in front of the car. Turning a little to the right so the whole track was in the shot would have helped.
One of my favorite shots I've taken at a drag race is of a top fuel dragster launching, and a blur of a blur of a kid in the stands in front of me holding his hands over his ears. It's not a great shot, but still one of my favorites because of the concept. I've tried several times to repeat it but never gotten it again.
There is a lot going on at a drag strip; noise, motion, smoke, and emotion. Try and capture those in photographs instead of static, almost car-show photographs.
