Before the 1978 season got underway, Peter Gregg had earned the IMSA crown four times, won the Trans Am Championship three times, and he had hat-trick at the Daytona 24 on his driving resume!
The new GTX class made room for the Porsche 935s to compete in the 1978 IMSA Championship and Gregg had a 1977 single-turbo 935 ready to go. He added to his IMSA successes by becoming the Champion for 1978. At the wheel of his Brumos Porsche, the American pulled out nine victories (including spending an hour in the #99 Brumos car, one of the first two twin-turbo 935s to reach American shores). Through the rest of 1978 he brought home 8 more first place prizes, setting sixteen qualifying and race lap records along the way!
Gregg set out to challenge the 1979 IMSA Championship using a single-turbo 935. The general consensus was that the twin-turbo model was the way to go, but the newly revised turbo equivalence factor allowed the single-turbo car to run a lower minimum weight. Gregg applied his driving style and talent to make the lighter car work to his advantage; no other driver could coax a single-turbo 935 to go anything like as fast.
Out front and on his own, where Peter Gregg spent a great deal of time during the 1978/79 IMSA seasons!
The end result was another IMSA title in 1979 that came as a result of eight victories from fifteen races. During the course of the season Gregg sat on pole ten times setting a qualifying record five times and set the fastest race lap ten times, setting six race lap records.
Peter Gregg drove his instantly recognizable Brumos Porsche 935 Turbo to enormous success in two consecutive seasons, demonstrating the awesome speed of the basic Porsche model that dominated IMSA until the arrival of the prototypes in 1981!
