Porsche 911 Turbo Tuning Program

It has 910hp at 910Nm, takes only 3.10 seconds from 0 to 100km/h and offers a top speed of 392km/h made possible by the modified double-clutch gearbox that goes with it. And in the form of a 'regular' 911 (997) Carrera convertible, with an unbelievable 780hp resulting in 381km/h, it holds the absolute world record for open-top motoring since October 2006.

Right, it must be a Porsche. But not just an ordinary one, no, it is the new Porsche 911 Turbo TRC 91 created by Nardo addicts 9ff. The artists from Dortmund turned the already extremely sporty bolide into one of the fastest and most powerful street-legal sports cars around the globe. The supercar's 3.6 litre biturbo 'boxer' engine was modified in great detail. Not only two special turbochargers increase the performance, but also the sport air filter, larger injectors, modified cylinder heads and a stainless steel exhaust system with special manifolds as well as high-performance catalysts, and, finally, an extensive increase in engine displacement resulting in 4.0 litres. All modifications are perfectly harmonised by means of the reprogrammed engine control unit.

Thanks to the modified racing front grill, the engine is provided with more air while the brake cooling has been improved by - discrete - additional air intakes. A boot lid made of carbon allows a maximum weight reduction to 1,300 kg. Optimum performance is brought to perfection through revised aerodynamics enhancing the powerful Porsche's driving stability while creating an atmosphere of even more dynamic elegance. The monstrous inner workings, however, do not reveal themselves that easily to a layperson. The experts at 9ff confined themselves to a slightly lower front apron and elegant 20-inch wheels with a larger braking system. New and shapely front spoilers, side skirts and redesigned rear wings add to the aerodynamic kit while the elegant and aerodynamically enhanced exterior mirrors are the crowning glory of the whole.

To sum it up, the 9ff Turbo TRC 91 was made for those among us who are real gentlemen - it is a decent horsepower werewolf.
