After lying idle for forty years, the Porsche 917 exhibited in the 24 Hours
of Le Mans Museum took to the tarmac again on 8 June 2010 at an exceptional
demonstration on the 24 Hours of Le Mans circuit, for the greatest pleasure
of all car racing buffs. On this occasion, the equally legendary Gérard
Larrousse, former pilot of this car and Le Mans winner in 1973 and 1974,
took the wheel again to drive back and forth a few times in the straight
section in front of the grandstand. A car of superlatives, probably the
most spectacular racing car having raced at Le Mans in the twentieth
century, it has been dubbed 'competition car of the century'.This
phoenix-like rebirth is the end result of painstaking efforts by the
Fondation du Patrimoine and Motul working together to safeguard and enhance
Après quarante années de repos et pour le plus grand plaisir de tous les
passionnés de course automobile, la Porsche 917 exposée au Musée des 24
Heures a repris du service le 8 juin 2010 lors d'une démonstration
exceptionnelle sur le circuit des 24 Heures du Mans. A cette occasion, le
non moins légendaire Gérard Larrousse, ancien pilote de cette voiture et
vainqueur au Mans en 1973 et 1974, a (re)pris place au volant pour
effectuer quelques allers-retours sur la ligne droite des tribunes. Voiture
de tous les superlatifs, probablement le plus spectaculaires des bolides
ayant couru au Mans au XXe siècle, elle fut nommée « voiture de
compétition du siècle ». Cette formidable renaissance a été rendue
possible grâce à l'action de la Fondation du Patrimoine et de Motul,
associés au service de la sauvegarde et la valorisation du patrimoine

This car was converted from a 512 S (Spyder) to a 512 M (Berlinetta)
Ferrari 512 S was the designation of 25 five litre sports cars built until
January 1970, related to the Ferrari P sports prototypes. The V12-powered
cars were entered in the 1970 International Championship for Makes by
the factory Scuderia Ferrari and private teams. Later that year, modified
versions resembling the main competitor Porsche 917 were called Ferrari 512
M (for modificata). In the 1971 International Championship for Makes, the
factory focused on the new Ferrari 312PB and abandoned the 512 which was
only entered by privateers. From 1972 onwards, the 512 (as the 917) was
withdrawn from the world championship following a change in the
regulations, and some 512 in private hands were entered in CanAm and
Porsche 908 at Nurburgring 1971
The Gulf Porsche 908/3 Flunder was raced to victory in the Nurburgring 1000
km of 1971 by Derek Bell - Jo Siffert.
The Porsche 908 was a racing car from Porsche, introduced in 1968 to
continue the Porsche 906/Porsche 910/Porsche 907 series of models designed
under Ferdinand Piech.
As the FIA had announced rule changes for Group 6 Prototype-Sports Cars
limiting engine displacement to 3000 cc, as in Formula One, Porsche
designed the 908 as the first Porsche sports car to have an engine with the
maximum size allowed. The previous Porsche 907 only had a 2200 cc flat-8
engine with 270 hp. The new 3-litre Flat-8 engine produced initially 257 kW
(350 hp) at 8400 rpm, as well as some teething problems. Also, being
traditionally air-cooled and with only 2 valves per cylinder, it was still
down on power compared to more modern F1 designs which delivered over 400
hp (300 kW), but were not suited to endurance racing.
The 908 originally was a closed coupe to provide low drag at fast tracks,
but from 1969 on was mainly raced as the 908/2, a lighter open spyder. A
more compact 908/3 was introduced in 1970 to complement the heavy Porsche
917 on twisty tracks that favored nimble cars, like Targa Florio and
Nürburgring. Sold off to privateers for 1972, various 908s were entered
until the early 1980s, often retro-fitted with Porsche 934-based 2.1-litre
turbocharged flat 6 engines.
Despite the more powerful 917 improving towards the end of 1969, the career
of the 908 would continue. On rather twisty and slow tracks like
Nürburgring and Targa Florio, the 917 was not suited well even after being
modified to the "917K". So rather than trying to make "one size fit all",
Porsche built dedicated cars for each type of racing track. Based upon the
lightweight and short Porsche 909 which was used in hillclimbing, the new
open cockpit version, the 908/3, was even shorter than the 908/2. This
version was successful in the 1970 Nurburgring 1000 km and the Targa
Florio, where typical speeds were only about half of the 240 mph (390 km/h)
which the 917LH long tails could achieve at Le Mans. The 908/02 in which
Steve McQueen finished second at the 1970 12 Hours of Sebring was also used
as a camera car for the Le Mans (film) in the race itself. Steve McQueen
originally intended to drive a Porsche 917 in the race, though this was
vetoed by the studio funding the film.
In 1971, vertical fins were added to the rear of the 908s which were
outpaced at the Targa by two Alfa Romeo Tipo 33s. All entered 908s crashed,
but Vic Elford had managed to set fastest lap. The next race at the
Nurburgring saw a 1-2-3 finish for the 908 in front of two Alfas Romeos,
but with Alfa scoring wins at Brands Hatch and Watkins Glen, it was proven
that these prototypes could even beat the 917s.
With the combination of the powerful 917 and the lightweight 908, Porsche
dominated the International Championship for Makes each year from 1969
through to 1971.

PORSCHE 917 ENGINE ANIMATION
Animated 3D model of the internal workings of a Porsche 917 engine. Model
was created in Solidworks. 180 individual frames, representing 2 full
engine revolutions, were then rendered in PhotoView 360. First 180 frames
are repeated 3 times to produce 30 seconds of video at 24 FPS. Each frame
took approximately 20 minutes to render with a resolution of 1280 X 1024.
