1977 Porsche 934.5

Bob Weber of Huntington Beach, California displayed this beautiful 934.5 at this years Amelia Island Concours.

The description read: In 1977, Porsche constructed 10 model 934.5s. This is the second of those. The first 934.5 was purchased by Peter Gregg and sold to and raced by Jim Busby under the Mitcom sponsorship.

On 2/22/77, Peter Gregg and Jack Atkinson, Brumos’ Crew Chief, flew to Zuffenhausen and purchased this 934.5 and a single Turbo 935. The 934.5 arrived in Jacksonville, FL, in February or March 1977. It required preparation by Brumos before debuting at the Road Atlanta IMSA race. It was disqualified by IMSA, so Peter Gregg decided to campaign the car in the Trans-Am racing series. The 935 purchased was not raced in 1977: it did, however, set the IMSA record at Daytona. During the 1977 SCCA Trans-Am season, the bodywork from the 935 would be used on the 934.5 in various configurations.

Peter Gregg won the 1977 SCCA Trans-Am Championship with this car. However, Canadian Ludwig Heimrath protested the championship and eventually the FIA ruled in Heimrath’s favor. Porsche, however, produced the poster below to commemorating Peter Gregg’s championship.
