For Sale: 1972 Porsche 911 2.5 SR in Maldon, Essex,

Vehicle Description


In 1967 the seeds were sown for what would become one of Porsche's rarest and most desirable models, the 911SR. At this time Porsche started development of the first 911 designed purely for motorsport, the 911R, which featured lightweight body panels and an uprated 210 bhp engine. To meet homologation requirements, the 911R spawned racing versions of the 911S and 911T, which competed in Group Three GT racing in the 1968 and 1969 seasons. These cars were similar to the 911R but had somewhat flared wheel arches to house the wider 7-inch rear wheels. By 1970 changes to the regulations allowed even wider wheels to be used and Porsche further redesigned the 911S to accommodate them. It was this model that Porsche used as the basis for a very limited run of cars that were designed specifically for GT racing and rallying and were designated the 911SR.
Built between 1970 and 1972 it is believed that out of a total of 1740 911S coupes, only 21 examples were constructed as SRs by the factory, although a number of other cars were subsequently retrofitted with an upgrade package that brought them up to SR specification. As each car was built for a specific purpose no one example was identical to another but they did share certain common features including the use of thinner gauge steel for body panels, aluminium engine covers and a stripped out interior. To save additional weight the metal seams were left unfilled, there were no rear seats, sound deadening was removed and a whole range of other smaller items were omitted. These weight saving measures reduced the overall weight to around 960kg, almost 100kg lighter than a standard 911S.
While the early SRs had 2.3-litre engines, the capacity had grown to 2.5 litres by the time production finished in 1972. Built with racing pistons, the cylinder heads had polished intake and exhaust ports and larger valves, together with racing camshafts and a racing exhaust system. The engines were equipped with Weber carburettors or Bosch racing mechanical fuel injection and featured a twin spark ignition system. Power outputs varied, but were typically around 270bhp at 8000rpm, which, in view of the lightweight construction, delivered fantastic performance including 0-60mph in less than 5 seconds and a top speed of around 150mph.
Other unique features included a long-range plastic 110 litre fuel tank plus a special large capacity race oil tank with twin larger bore front oil coolers, both unique to the 2.5 SR.
Transmission was via a new 915 gear-box fitted with an extra oil cooling pump, limited slip differential and competition shafts.
Wheel sizes were dependant on the intended use for the car but were typically 15-inch in diameter, and up to 8-inches wide at the front and 9-inches at the rear. The suspension was lowered with A-arms to the front and semi-trailing arms at the rear and with uprated hydraulic shock-absorbers and a choice of anti-roll bars. Brakes were also uprated to ventilated discs with a dual-circuit system and could be fitted with aluminium 908 "quick release" front callipers (magnesium was also offered as a works option) and special aluminium rear callipers with racing-pads and brake-fluid.
A 10,000 rpm tacho was fitted inside the dashboard, together with twin-ignition coil cut-offs below, Bosch battery isolation switches inside and out and a fire extinguisher system.
This particular example is a 1972 model and consequently features the larger 2.5 litre engine. It was constructed in April of that year and sold by Porsche's Munich distributor to Anton "Toni" Fischhaber. Fischhaber is a well-known Bavarian racing driver who, over a career spanning 28 years, won six European Championships, one German Hill Climb Title and at least 200 individual victories driving a variety of different cars.
After a moderately successful 1971 season at the wheel of an Alfa Romeo, Fischhaber was hungry for further success and decided to start afresh in 1972 with a new 911SR, the car offered here, which he entered into the European Hill Climb Championship and duly won. In addition to the Championship, he also won numerous other local hill climbs around his home region of Bad Toelz and also entered the 1000km race at the Nurburgring where he finished 14th. The 1973 season was less successful for Fischhhaber due to some bad luck and some rather significant technological advances made by the competition. The latter prompted Fischhaber to make further modifications to his Porsche and for the 1974 season the car featured a rear spoiler and modified bodywork based on the new Carrera RSR 3 litre car.� These upgrades obviously worked and delivered Fischhaber his third European Hill Climb Championship and the second in the same car.
With the conclusion of the 1974 season, the Porsche was sold to Switzerland and subsequently passed through a limited number of owners before being acquired by a well-known collector in the UK who had the car extensively restored by one of the world's leading Porsche specialists. As a result of the work undertaken it is presented today in its original 1972�configuration with�factory colour scheme of Light Yellow with Black interior and importantly retains its original body shell. Offered in exceptional condition throughout and accompanied by an extensive history file with race results and photographic record of the restoration it provides an incredibly rare opportunity to acquire one of Porsche's most desirable racing 911s with a fantastic competition pedigree.
