The new Porsche 911 GT3 Cup is entering the 2008 motorsport season with engine output increased to 420 bhp. 265 units of this production-based racing car will be built, marking a new record for a car of this category.
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.
