I'de like to point out that the difference between 300 mph and 330mph, for a given car is 21% in terms of kinetic energy. Although the speed increases 10%, the energy increases 21%. It is proprtional to the square of the speed. forgetting weight, 300 x 300 =90000. 330 x 330 = 108900. So for a seemingly small increase in speed they gain 20% in energy. I know that alone wouldn't have made a difference in the case of Scott Kalitta, but the point is that the energy that has to be dissapated whether by brakes, chutes, sand, or roll cages is greatly increased without any improvements in the means available to do so. I think the NHRA got the wake up call they needed (IMHO). I'm glad they seem to be doing something about it.
