The early 1970s marked the culmination of Porsche’s dominance in the prototype era and the beginning of a factory-supported GT racing program based on the 911 platform. In 1973, the new Carrera RSR 2.8 dominated its class and won the Targa Florio outright, defeating factory-entered sports racing prototypes. The following year, an experimental RSR 2.14 Turbo entered by the Porsche factory team placed a remarkable 2nd Overall at the 24 Hours of Le Mans. These successes led Porsche to develop two new state-of-the-art 911-based racing cars to compete in the FIA world championship.
Introduced for the 1976 season, the 934 was Porsche’s highly anticipated Group 4 GT variant of the all-new turbocharged 930 – a factory-built racing machine that maintained close ties to its road car counterpart.
On the surface, the 934 retained much of the classic 911 form, though it was distinguished by riveted GRP fender flares, a prominent front air dam, and three-piece BBS wheels. Under the skin, Porsche’s latest production-based racer was a carefully engineered thoroughbred. Equipped with 917 brakes, rear coil-spring suspension, a full aluminum roll cage, and a turbocharged, three-liter flat-six, the 934 accelerated from 0 to 100 mph in about 12 seconds and had a top speed approaching 190 mph.
Porsche constructed 31 examples of the 934, all in 1976; they were sold to private racing teams and campaigned with great success in a variety of regional and international series. As Porsche had intended, the 934 expanded on the success of the RSR racing program, capturing the European GT Championship and the Trans Am Championship in North America.
This Porsche 934, chassis 930 670 0162, is regarded among the very best of its type, with an outstanding decade-long international racing history and a complete, unbroken provenance.
According to factory records, this 934 was completed in Porsche’s racing shop during spring 1976 and assigned production number 106 3717. Originally finished in a distinctive Light Yellow livery, the 934 was sold new to Angelo Pallavicini of Zurich.
A well-known car enthusiast, collector, and dealer, Pallavicini began his motor sports career in 1972, racing BMW 2002s and CSLs in touring car events. In 1975, he acquired a Carrera RS 3.0, which he entered in the European Championship for GT cars and in the German DRM series.
Pallavicini began racing the new Porsche 934 in 1976, campaigning it under the Corse Pallvano banner in five European GT events, as well as in club races and hill climbs. After racing with success in club events throughout the 1977 season, Pallavicini achieved his greatest success in 1978, winning the FIA Group 4 championship. During the season, Pallavicini and his Swiss co-drivers Peter Bernhard, Enzo Calderari, and Marco Vanoli, captured Top 10 finishes at major events including the six-hour endurance races at Dijon, Misano, Silverstone, and Vallelunga.
In 1979, Pallavicini took this 934 to the US to take part in the 24 Hours of Daytona; he finished 10th Overall and 4th in the GTO class. Following Daytona, Pallavicini sold the Porsche to Werner Frank, a successful Chicago-based Toyota dealer and racing driver.
Frank continued to campaign the 934 through the 1983 season, often sharing driving duties with Canadian Porsche racer Rudy Bartling. During this period the car ran primarily in IMSA events, though it was entered in major international endurance races in 1980 (Daytona and Sebring) and 1981 (Watkins Glen and Road America).
After the 1983 season, Frank sold the Porsche to Rick Borlase of Las Vegas, who continued to race the car in IMSA events through 1986. Remarkably, during its penultimate outing in March 1986, the 10-year-old 934 captured a fantastic 11th Place finish at Sebring, driven by Borlase, Michael Hammond, and Jim Torres.
In 1988, Borlase sold the retired 934 to Swiss collector Sid Ho, though he never took delivery and the car remained in the US. In 1990, Jim Torres purchased the car, which he had raced four years earlier, and restored it in his own highly regarded workshop, Burbank Coachworks in California. During this process, the car was stripped to the bare tub, refinished in the correct Light Yellow livery, and carefully rebuilt using many of its original 1976 components, which had fortunately remained with the car during its active US racing career.
After the comprehensive restoration was completed, Torres sold the 934 to collector Carlos Cortez in 1997. During the following decade, the Porsche was owned by several noted collectors, saw minimal use, and was maintained by respected specialist Jerry Woods of Campbell, California.
The current owner, a knowledgeable collector of significant racing Porsches, acquired the 934 from Monte Shelton in 2009 and has since had Rennsport Historic Race Cars carry out any required maintenance, including the recent installation of a new fuel bladder.
Today, chassis 0162 is beautifully presented in its original Light Yellow, equipped with proper, period-correct components, and offered with a file of documentation that includes an FIA Historic Technical Passport, a 1979-issue logbook, photo album, and a collection of paperwork ranging from service records to articles.
Restored and maintained by noted Porsche specialists, this outstanding 934 would make an ideal entry for any number of historic racing events including Le Mans Classic, and it could be a standout at marque gatherings such as the Rennsport Reunion in September 2018. Not only is this exceptional Porsche a ticket to the most exclusive historic motoring events, its impressive 10-year international racing history, vibrant period livery, and outstanding presentation place it among the very best examples of a rare breed. Significantly, unlike many racing 911s, this factory-built Porsche race car possesses an unbroken provenance and a singular identity, with its history well documented in several important books on the marque and model.
A marvelous example of Porsche’s rare mid-1970s Group 4 racer, this 934 is worthy of serious consideration.
