Years ago, I used to run local S/P with an 11.50 footbrake car, and I did win a number of races. Since then, I have seen lobbying from the RED guys for 1/8th mile, crosstalk, across the line burnouts, onboard computers, and ETC. Every one of these changes gave them another advantage. Now you see few door cars in S/P, many tracks have taken to running dragster and door car seperate for a few rounds to compensate. I have no fear of running a 7.20 dragster in S/P with my 10.30 door car on a 1/4 mile. On 1/8th mile, it burns my rear end to look over at a dragster and see the driver with his head straight forward and running dead on to my .01 over. Yes, he probably treed me, too, but the 1/8th took away my ability to play a little on the top end. Only a few of these new breed of drivers play the top end at all, they dial in with a weather station, let go of the button, drive it all out, then look at the numbers on the slip.
