Porsche 911 GT3 Cup

porsche carrera tuning

With the 2008 motorsport season almost upon us, Porsche have upped power on their new 911 GT3 Cup and will produce a category record 265 examples of the now 420 hp production-based racing car. Produced in Stuttgart, the 26 examples heading for racing use in the Porsche Mobil1 Supercup, Porsche Carrera Cups and GT3 Cup Challenges will be delivered early March next year.

Gaining 20 hp over the output of the previous model, the 3.6-litre six-cylinder boxer unit now produces 420 hp. And with a kerb weight of just 1,150 kg in race trim and therefore a power-to-weight ratio of 2.7 kilos per horsepower, is some 245 kg lighter (at 3.4 kg / hp) than a standard new 415 hp GT3. A six-speed sequential transmission allowing for seamless full throttle shifting has been optimised for the new more powerful engine characteristics.

Keeping up with the production version, the GT3 Cup's rear end has been significantly updated, among the changes being the insertion of air venting slits to provide better heat dispersal. A modified exhaust system, producing a more commanding Formula 1 reminiscent sound, and exclusive PCCB Porsche Ceramic Composite Brakes, which reduces weight by 20 kg and increases braking response and lifetime reliability.

The new Porsche 911 GT3 Cup is entering the 2008 motorsport season with engine output increased to 420 bhp. The car will be raced in the Porsche Mobil1 Supercup, the world’s fastest international brand trophy, and worldwide in national Porsche Carrera Cups and GT3 Cup Challenges. 265 units of this production-based racing car developed in Weissach will be built on Porsche’s production line in Stuttgart-Zuffenhausen, marking a new record for a car of this category.

The most significant modification compared with last year’s model is the new rear end following the design of the production model. Air venting slits ensure better dissipation of heat at the rear. The 3.6-litre six-cylinder boxer engine developed in Weissach is also based on the street-legal GT3 and develops maximum output of 420 bhp, 20 horsepower more than on the previous model. The sequential six-speed transmission with interruption of engine power enables the driver to shift up under full throttle without disengaging the clutch. The transmission itself has been optimised and the gear ratios adjusted to the characteristics of the engine. Weighing 1,150 kg in race trim, the new 911 GT3 Cup has a power-to-weight ratio of 2.7 kg per horsepower.

The 26 units of the 911 GT3 Cup built for the Porsche Mobil1 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. Compared with conventional brake discs, PCCB reduces unsprung masses by 20 kg and sets new standards in terms of responsiveness, resistance to fading, and a long service life. The racing cars entered worldwide in the Carrera Cup feature a modified exhaust system and steel brake discs.

Porsche’s Racing Department in Weissach is responsible for the fine-tuning and running in the 911 GT3 Cup cars. Deliveries will be directly from Weissach, depending on the country of destination and the schedules to be observed. While the cars for the Carrera Cup New Zealand have already been shipped, delivery of the racing cars for the Porsche Mobil1 Supercup and the Carrera Cup Germany is scheduled for early March 2008.

New Cars 2011 Porsche 911 Carrera GTS

As standard, the Porsche 911 Carrera GTS has a six-speed manual gearbox and the seven-speed Porsche Doppelkupplungsgetriebe (PDK), is available as an option. Compared Carrera S. The upper speed GTS with manual transmission increases 2mph to 190 mph. In general, the acceleration from zero to 62mph is improving, 0.1 seconds; for GTS Coupé with PDK and Sport Chrono Package Plus Sport Plus mode, the source sprint takes only 4.2 seconds.

Special attention was paid to charge exchange in the 3.8-litre flat engine delivering 408 hp: In a special resonance intake manifold, six vacuum-controlled tuning flaps switch between power- and torque-optimized geometry whereas in a Carrera S power unit there is only one tuning flap. Thus, maximum torque of unchanged 420 Nm is already available at 4,200 rpm, 200 rpm earlier compared with the Carrera S. Add to that a sports exhaust system with two dual tailpipes. Their outer shells are painted in black and their inner tubes are polished on the outside and nano-coated.

Unique within the 911 Carrera family, the GTS combines the 44 millimetre wider body of the all-wheel drive Carrera 4 models – including widened rear track – with a classic rear-wheel drive configuration. The Porsche 911 Carrera GTS sits on 19-inch centre-locking RS Spyder alloy wheels, painted in black with high-gloss finished rims, with 235/35 ZR 19 tyres on the front axle and 305/30 ZR 19 tyres on the rear. Further features include the SportDesign front apron with spoiler edge painted in black, special side skirts also in black, and the Carrera GTS logotype on doors and rear lid, in black or silver depending on the body colour. The area between the two tailpipes on the rear apron is also finished in black.

The new Porsche 911 Carrera GTS will have its global debut at the 2010 Paris Motor Show on October 2 and goes on sale in the UK in December, priced from £76,758 for the Coupe and £83,493 for the Cabriolet.
