WinnerMaster engine builder Tony Bischoff of B.E.S. has been red hot in the Pro 5.0 category. A 646ci engine with three stages of nitrous gets this Cougar motivated into the 6.60 zone. Bischoff shook the tires and ran 6.91 in Round 1, but he beat Don Walsh Jr., who had problems. In Round 2, he eliminated Michael Hauf, the number-two qualifier. It was the closet run of the day-6.67 to Hauf's 6.68. In the finals, Bischoff's competitor, Kelkboom, broke, and Bischoff singled for the win with a 6.68.
