Monster trucks vs jet powered semi truck! This is clearly for entertainment , and entertaining it is!
They were bracket racing. The dial in (predicted elapsed time) for the monster truck was slower, so he got the head start. The jet truck then had to chase the monster truck. The monster truck dialed 8.12 seconds and ran 8.128 seconds in the 1/8 mile. The monster truck got to the finish line first and ran right on his dial in (predicted elapsed time) so he got the win light.
You just have to enjoy to ridiculous machines pitted against each other. Obviously Grave digger isn’t really made to run on the drag strip, I’m not really sire what a jet truck is for except just Awesome!
