nhra stared in the 50s and all there races have been 1/4 mile. then they thought they would slow top fuel by shutting them off at 1000 feet but we all see they didn't work they still run 340 mph and the only thing they run a 1/8 mile is jr dragsters for little kids. man up and run the rest of the race. and for you guys saying its easer on the motors well if you cant build a motor to run 1/4 mile you need to find a new engine builder. did you guys ever see a dirt car race? now them motors take a beating hot cold spinning and sliding lap after lap. if it wasn't for these guys trying to run 3000 hp on 275 tires we would not need half track racing.
