This acceleration data seems to be so slow... The standart Carrera S does 1/4 mile in 11.8 sec, and 0-200 in 13.2 sec already... Apparently, the test for the Powerkit was horribly done. Laptime is impressive though.
X51-Powerkit is available for the 991 Carrera S models.
Engine specifications are the same as the Club Coupe's:
The Carrera S Powerkit contains modified cylinder heads and camshafts, a newly developed variable resonance-type intake system with switchable flaps, center radiator, a sports exhaust system with two dual tailpipes in a unique design with a concise sound, the Sport Chrono Package with dynamic engine mounts, an optimized engine management plus a new engine bay styling with a
titanium-colored cover and inserts in carbon fiber.
