Motor Engineers of Warrington and this unique road-going 917K Replica is rumoured to have cost well in excess of six figures. It is based on a mid-engined 1970 914-6 donor car, 'ARP 496J' and is both registered and taxed as a Porsche. It is completeley road legal and has a current MOT until July 2007. It has covered just 11,618 miles! Fed by twin variable-boost GT2 turbochargers, its dry-sump 3.3 litre type 930 flat-six engine also boasts a fully plumbed-in 'wet' nitrous-oxide injection system. Topped by dual intercoolers and a horizontal multi-blade fan, this formidable powerplant is coupled to an inverted manual 911 Turbo gearbox complete with its own oil cooler and oil pump. Intended for both (hyper) fast road and track use, 'ARP 496J' features highly modified suspension and 911 Turbo sourced disc brakes. Reportedly handmade from blueprints, its lightweight fibreglass bodywork is finished in Gulf Oil's evocative light blue and orange colours. Sparse but functional, the replica's cabin sports high-backed seats, a centre-mounted instrument binnacle, Camus LCD display screen (a camera shows behind the car with screen in-cabin), in cabin intercom system for communication between driver and passenger, fire-extinguisher pull, ignition cut-out switch and starter button. A truly unique proposition, this incredible left-hand drive Porsche supercar is worthy of the closest inspection. The car also has some wonderful additions: the tailfin was signed at Brands Hatch in 2006 by Richard Chamberlain, Mark Finsburg, David Piper and Richard Attwood and the seat belts are from the 1996 Championship Williams driven by Damon Hill (with provenance). If you could find an original the price would start at approx £1,250,000 and go up from there depending on the history! REDUCED from £79,950 to £72,500 Additional interesting history & background of the Porsche 917K: The Porsche 917 Sports Racer (launched at the March 1969 Geneva Motor Show) cost 140,000DM (equivalent to ten 911 road cars). Successfully exploiting a loophole in the contemporary World Championship of Makes' regulations that required just twenty five examples to be made for a design to qualify as a 'production' sports car, it was duly homologated by the CSI (Commission Sportive Internationale) the following month. Derived in part from the 908, the new sports racer was constructed around a tubular aluminium spaceframe chassis equipped with all-round coil-over wishbone suspension and four-wheel ventilated disc brakes. Powered by a longitudinally mid-mounted flat-12 engine of 4.5 litres (later 4.9, 5.0 and 5.4 litres) allied to four- or five-speed manual transmission, the 917 weighed approximately 800kgs. Poject leader Ferdinand Piech's obsession with weight-saving was so extreme that it led the transmission engineers to fit a balsa wood gearknob. Unpopular though this blister-inducing component was with the Works drivers, they reserved most of their criticism for the car's wayward handling. So wary of the 917 were they that Porsche had to hire in privateers David Piper and Frank Gardener when the model made its international debut at the 1969 Nurburgring 1000KM. Such was the 917's turn of speed - it had a 30km/h advantage over anything else down the Mulsanne Straight - that suspicion over its unpredictable high-speed behaviour was initially levelled at the featherweight chassis and suspension. However, despite Stuttgart carrying out extensive modifications in these two areas, the problem persisted during the rest of the season. Faced with the prospect of increased competition from the new Ferrari 512, Porsche entered into an agreement with John Wyer and the JWA 'Gulf' Team for 1970. Allowed to participate in the factory's official development programme, it was JWA's John Horsmann who first suggested trading some of the 917's low-drag efficiency for downforce. Experimenting with a new wedge-shaped tail (not dissimilar to that found on the 917 Spyder), he proved that the closed car's stability issues were aerodynamically not mechanically induced. Refined by Porsche themselves, the result of Horsmann's work was the legendary 917K (Kurzheck or Short Tail) that would go onto win Le Mans in both 1970 and 1971 (as well as having a starring role in Steve McQueen's cinematic homage to the great 24-hour race). Scoring no fewer than fifteen victories in the World Championship of Makes between 1969 and 1971, the uber-Porsche then made a successful transition to Can-Am Racing where the combination of Roger Penske (team owner), Mark Donohue (supremely gifted driver) and the turbocharged 917-30 (5.4 litres, 1100bhp) proved unbeatable. Arguably, the most important Porsche competition car yet built, the 917 was responsible for some of the most dramatic racing ever witnessed.
