In sport, there's always room for a little improvement.

The 911 was born out of passion for the sports car. The source of this passion can be traced back to the Porsche Development Centre in Weissach. Here, our designers and engineers give their all to produce breakthrough after breakthrough, applying themselves with dedication, heart and soul, a love for detail and a desire to redefine the limits of supreme performance. The most recent accomplishment is the new Carrera S Powerkit, which is now available for the 911 Carrera S or Carrera 4S models (Type 991).

In plain figures, we have managed to increase power output from 294 kW (400 hp) to 316 kW (430 hp) and improve acceleration from 0 to 100 km/h by 0.1 seconds. The 911 Carrera S models with PDK and SPORT PLUS button complete the sprint in an impressive 4.0 seconds. The fastest variant in the range reaches a top speed of 308 km/h.

To develop the Powerkit, a number of sophisticated measures were needed . The cylinder head intake ports have been reworked and given a polished finish. The stroke of the intake camshaft has been increased and the electronic engine management adapted accordingly.

The highlight of the Carrera S Powerkit is the newly developed variable resonance intake manifold with six plus one switchable valves. This innovation enables the system to switch between power- and torque-optimized geometries and deliver a boost in power output, particularly in the upper speed range. The extra heat generated by power increase is dissipated by an additional center radiator.
