Porsche 911 Carrera S
Significantly, a new X51 Power Kit is available for the already more powerful 2006 Porsche 911 Carrera S Coupe. 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 Coupe’s 3.8-liter flat six-cylinder engine goes from 355 (SAE) to 381 (SAE). Acceleration from a standing start to 60 miles per hour (96 km/h) drops by an amazing two-tenths of a second — to just 4.4 seconds with a manual transmission and to only 4.8 seconds with Tiptronic® S.
With the manual gearbox, the Carrera S Coupe’s top speed climbs to 186 miles per hour, the magical 300- km/h figure that puts this Porsche into the ranks of the world’s “super cars.” (Top speed on the test track for the 2006 Carrera S Coupe with Tiptronic S transmission is 182 mph (294 km/h).
