Porsche Exclusive has released a new power enhancement kit for its 2013 911 Carrera S that boosts the power of the 3.8-liter boxer engine from 400 hp to 430 hp. This allows the sports car to sprint from 0-60 mph in only 3.9 seconds with in Sport Plus mode. Maximum top-track-speed has also increased by three mph to 191. Some newly designed cylinder heads and camshaft profiles offer better engine breathing and along with modifications to the electronic engine management system are responsible for the power increase. Also included is a new variable resonance intake system design with six air flaps and an additional resonance flap. An additional center radiator, unique sports exhaust system and the Sport Chrono package with dynamic engine mounts round out the performance changes. Exterior changes include 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 and comes with a special front spoiler lip with additional air intakes.
