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.
