The Porsche 997 GT3 Cup was developed based on the current 911 997 generation, which has been gradually established in the market since the end of 2004.
The 997 GT3 Cup features a watercooled normally aspirated 3.6 liter flat-six boxer race engine based on the current 997 GT3 street legal model. The powerplant includes four-valve technology, dry-sump lubrication, central air intake leading to a two-stage resonance intake distributor, sequential multi-point fuel injection and a racing exhaust with a fully controlled catalytic converter (400 cells). It provides 309 kW (420bhp) and 420 Nm (310 lb-ft) and revs up to 8,400 rpm.
The power is transmitted to the rear wheels only via a six-speed sequential dog-type gearbox featuring an oil-water heat exchanger, single-mass flywheel, 5.5 inch triple-disc sintered-metal clutch and a limited slip differential 40/60 per cent.
The 997 GT3 Cup is equipped with a state of the art suspension equipment featuring a front setup consisting of a McPherson spring strut axle, Sachs gas pressure dampers, double coil springs (main and ancillary spring) and is equipped with three-piece BBS light-alloy wheels (9J x 18) with central locking. The rear axle features the same dampers and spring setup and is designed as multi-arm axle with rigidly mounted axle subframe and also is fitted with three-piece BBS light-alloy wheels (11J x 18).
The bodywork consists of a monocoque body made of hot-galvanised steel, an aerodynamically optimised front end with front spoiler, doors with side frames made of Carbon fibre, reinforced plastic door panels and rear body panels as well as a rear lid made from Carbon fibre. It features air jacks, a welded-in roll cage, bucket-type racing seat (on driver's side only) with flame-resistant seat cover, six-point seat belt, adapted for use of the HANS Head and Neck Support and an electric fire extinguishing system.
The 997 GT3 offers a 90 liter fuel tank and weighs approximately 1150kg resulting in a power to weight ratio of 2.7kg / bhp.
26 units of the 911 GT3 Cup built for the Porsche Mobil 1 Supercup feature a special exhaust system with an even more striking sound pattern reminiscent of the Formula 1 racing scene as well as PCCB Porsche Ceramic Composite Brakes as exclusive highlights.
