    I have been following NHRA for a while now, since the Driving Force reality show. Some of the info is a little dated; NHRA now runs a 1,000' foot track not a 1/4 mle anymore and the ET has now dropped to 3.735 with top speed up to 327.90 for 1,000 feet, simply amazing!

        When did they shorten up the course so much from 1/4 mile?

          After Scott Kalitta was killed a few years back they shortened the track to 1000' to allow more room for shut down. Due to the increasing speeds the NHRA reduced the amount of nitormethane in the fuel to slow down the top fuel dragsters/funnycars. Then the Scott Kalitta accident happened so then the NHRA shortened the track for the top fuel catagories because not all of the tracks have the same amount of shut down. This way the shorter tracks would have at least as much as the longer tracks and this also gives more room at the longer tracks.

              I believe this was published a few years ago in Mopar magazine that comes directly from Chrysler. I loaned my copy to a friend and never got it back. Thanks for republishing this. It is amazing what has been developed from the old Hemi. Karl Kiekhaefer kicked azz on the NASCAR tracks with the first generation Hemi in the mid-fifties. He was generally despised by the fans because of his total domination during the years he raced. He is credited for developing the paper air filter because of the dirt tracks they ran on. **** near bankrupted Mercury with his stock car program.
