Brandon Barr


Having run a best of 11.70, Brandon's Formula was off the pace with a best elapsed time of 12.33 at 114 mph. A bent axle delivered severe wheel hop, which prevent him from getting out of the hole properly. "The wheel-hop was so bad that it actually shook the ignition wire loose," noted Brandon. That malady coupled with some spark plugs that weren't too happy after the first nitrous pass kept Brandon from improving his times.
