If Porsche's seventh-generation 2013 911 Carrera S doesn't have enough power to suit you, don't despair. You don't have to spring for a Turbo to up the ante.
Porsche Exclusive has just announced availability of a new power enhancement kit developed for the Carrera S that boosts the output of the 3.8-liter boxer engine from 400 to 430 horsepower.
With that extra helping of power, the 911 Carrera S Coupé can sprint from zero to 100 km/h in 4.0 seconds, with PDK in Sport Plus mode. The kit also increases the top speed by four km/h, to 306 km/h with PDK and to 308 km/h with a seven-speed manual gearbox.
Defying conventional logic, that enhanced power has not affected fuel economy – at least not on the New European Driving Cycle (NEDC), where its fuel-consumption figures remain unchanged despite its 7% power increase.
Enabling that additional power, without increasing fuel consumption ratings, are newly-designed cylinder heads and camshaft profiles that offer better engine breathing, as well as modifications to the electronic engine management.
The Powerkit also features an entirely new variable-resonance intake system design with six throttle plates and a resonance valve.
An additional centre radiator keeps the higher specific power from overloading the thermal management system of the six-cylinder engine.
Low exhaust back pressure is achieved by a sport exhaust system, equipped with two sets of twin tailpipes with distinct styling. At the press of a button, the exhaust system is dethrottled and the two exhaust paths are merged to generate a powerful engine sound.
Dynamic engine mounts round out the performance changes, while a titanium-coloured engine cover with carbon inlays provides a visual Powerkit highlight. The kit also includes Porsche's optional Sport Chrono package.
The Powerkit will become available in early fall of this year.
Porsche Exclusive has also announced aerodynamically tuned exterior components for varying levels of customization.
A new front apron now extends lower and features the open air intakes from the Sport Design package. A fixed rear "ducktail" spoiler is also available.
The top upgrade is the Aerokit Cup with an additional fixed rear wing over the standard rear spoiler. It comes with a special front spoiler lip with additional air intakes.
Other new Porsche Exclusive products for the 911 Carrera include an Exterior package with various components in body colour and numerous interior upgrades such as decorative trim in materials ranging from brushed aluminum to carbon.
