Jim Busby


Mid Ohio was the twelfth round of the 1976 IMSA Camel GT Challenge. The title was to be hardly disputed between Al Holbert and Peter Gregg. This race also featured, for the first time, two Porsche 934s which were now allowed to run for the win. Michael Keyser, in a Chevrolet Monza, looked fit in the first place, leading the race but for one lap. Al Holbert took the lead, then, while Michael Keyser would be back after losing some time being bumped off the track by a backmarker. Peter Gregg would keep his BMW 3.0CSL right behind the Chevrolet Monza. He knew that his car would require only one pit stop compared to the two required by the V8 Chevrolet. George Follmer was not far away, in the Holbert Racing Porsche 934. After twenty seven laps, Peter Gregg would pass Al Holbert and take the lead. In fact, Al Holbert was struggling with his gearbox, and he could only count on third gear. Peter Gregg was now ahead of George Follmer, who was to pit for fuel, and lose about one half minute. Jim Busby could move up and would fight against George Follmer for second place.

Moments later, it was the Peter Gregg Racing BMW 3.0CSL which was back in the pits for fuel. Things would not turn as expected, however. Tires and fuel, as well as a driver change would require a minute or so, as the accelerator or throttle linkage was acting up. Hurley Haywood would be back to the track, but he would spin a few laps later, and lose another 25s. The race was now a 934 versus Carrera RSR battle. All Porsche, with the BMW far enough behind the duet. Still, it looked like Jim Busby was willing to stick his car behind the 934, waiting for George Follmer to falter. Then the Porsche 934 was in the pits, seemingly for refueling, but in fact, the left rear wheel had worked loose. Seven laps would be lost. Doc Bundy would take over, but no more for the win. Jim Busby was now in the lead, with one minute over Peter Gregg-Hurley Haywood's BMW 3.0CSL. He would pit for fuel and still maintain a 30s gap over the bimmer. Hurley Haywood would try to close in on Jim Busby, but it would be to no avail. A late bump with another car almost ruined the Porsche Carrera RSR chances, who hit the car with his front spoiler, nearly loosening it. It would not tear apart, so he was not to be black-flagged. Jim Busby won with a 16s gap over the BMW. Al Holbert was still third, followed by Mike Brockman-Steve Durst Chevrolet Corvette. Brad Frisselle and John Morton were in fifth place, taking the GTU win in his Transcendenthal Racing Datsun 240Z, well ahead of second place GTU finisher Bob Speakman, also in a Datsun 240Z. Jim Borsos and Dennis Aase were next, in a Porsche 911.
