Even though there is some driver error and variables in drag racing, there is a soooooo much more in road racing. Road Racing no doubtedly would be more fun, and exhilirating- NO DOUBT AT ALL. But, unfortunately the hundreds of thousands of variables in one lap really does not give the real world data (and driver error measurements) that a simple quarter mile pass will do; at least not that I can imagine. Trap speeds tell alot about gains, are very tangible, and quite frankly they are hard to argue. The bottom line is that anyone wishing to quantify real world gains should be using a dragstrip in conjunction with a chassis dynomameter. In some cases some roll ons with other "known" vehicles is ok to get a concept of whats going on, although I wouldnt put everything into that.

jp the vbox would be a good start though.
