back when my car had a single resivor master cylinder and running 11.70's at around 115-120? it sometimes would be a pain to stop on the 1st return road <we have 2 seperate roads> and our 1st return road is a little over a 1/4 mile past the finish line. that double resivor sure helps now. i agree with the crew chief having a cut off switch all monster trucks have a remote that the officals can kill the truck if it gets out of hand. we need the same for nhra fuel cars..
