I think most people will agree the speed is at the second half of the track.1/8 + second half of track = 1 drag race
I do have a friend that races a BBC that likes 1/8 mile racing because his motors blow up after a few 1/4 mile races. I grew up 11 miles from a 1/4 mile track didn't make sence to go 75 miles to race only 1/2 a track. Even Tampa was only 60' short & Lakeland was & still is 660' short.
