Porsche 911 Carrera S Cabriolet
From Porsche press: Additionally, the X51 Power Kit is available for the already more powerful 2006 Porsche 911 Carrera S Cabriolet. Featuring revised cylinder heads, carbon-fiber air cleaner housing, an aluminum air intake system, a reprogrammed engine control unit, and revised exhaust manifolds with sport exhaust and specially tuned tailpipes, the kit increases power, cuts acceleration times and increases the top track speed of this special model.
With the kit, the horsepower rating of the Carrera S Cabriolet’s 3.8-liter flat six-cylinder engine increases from 355 (SAE) to 381 (SAE). Acceleration from a standing start to 60 miles per hour (96 km/h) drops by two-tenths of a second — to just 4.5 seconds with a manual transmission and to 4.9 seconds with Tiptronic® S.
The larger and more powerful 3.8-liter engine in the 2006 Porsche 911 Carrera S Cabriolet is only one of several features that distinguish a car that has such standard equipment as Porsche Active Suspension Management, larger brakes with red-painted calipers and larger wheels. Additional standard fitments include Bi-Xenon headlights, a sports steering wheel, aluminum-look interior trim and dials and a silver-colored rear deck lid logo.
The 2006 Porsche 911 Carrera and 2006 Porsche 911 Carrera S Cabriolets may look similar to the 911 Cabriolets that came before, but as part of the newest generation of 911s, they are thoroughly updated models inside and out. They feature six-speed manual transmissions or optional Tiptronic S gearboxes with shift buttons on the steering wheel, variable-ratio rack-and-pinion steering, Porsche Active Suspension Management (optional on the 911 Carrera and standard on the 911 Carrera S), an optional Sport Chrono Package Plus that records and displays lap times, as well as a passenger compartment with several seating options and a long list of active and passive safety equipment.
