1977 Porsche 934.5

This is one of only ten Porsche-built 934.5 race cars. The Porsche 934.5 is a prime example of the intense competition in world sports car racing in the late 1970s. The Porsche 930 Turbo was configured for racing in two FIA categories: Group 4 (934) and the fastest Group 5 (935). In the US, the 934 was accepted in Trans-Am in 1976, although not into IMSA until the following season. The 1977 IMSA rules allowed the 934 to be even more heavily modified using numerous 935 parts. The Porsche factory created ten IMSA-only versions called 934.5 late in 1976. George Dyer purchased this car new to compete in the 1977 IMSA championship. After a competitive season, Dyer sold the car to Bruce Canepa. He would go on to successfully race the car in IMSA and Trans-Am. The car's high point was the 1979 24 Hours of Daytona. With teammates Rick Mears and Monte Shelton, Canepa finished third overall. A spectacular result considering they were an independent team racing a 3-year-old car against the brand new factory Porsche 935s.
