For the first time ever, the base 911 Carrera comes equipped with turbochargers.  While purists may scoff at the idea of a boosted powerplant, the fact of the matter is that the cars are producing more power, more efficiently, than ever before.  The Carrera, S, and GTS share a 3.0L engine and take advantage of varying turbocharger size, boost pressure, and other tuning changes to maintain the hierarchical power difference between tiers.  The base Carrera utilizes turbochargers with a 49mm compressor producing around 13 psi of boost to pump out baseline numbers of 367 HP and 336 TQ measured at the wheels.  Our Stage 1 calibration file increases power to 435 HP and 460 TQ when utilizing 93 octane fuel.


With the Carrera S having slightly larger turbochargers (51mm compressor) and utilizing 16 psi of boost pressure from the factory, we saw baseline power figures of 403 HP and 376 TQ measured at the wheels.  The COBB Stage 1 map offers additional power across the board, as indicated in the following dyno chart.  This calibration is intended to be used on an otherwise completely stock car, requiring no mechanical modifications.  On 93 octane, we saw maximum gains of over 30% in some areas.  Peak power numbers are increased to 452 HP and 483 TQ at the wheels.


The Carrera GTS offers even larger turbochargers than the Carrera S, the compressor measurements come in at 55mm.  With those turbochargers producing right around 18 psi of boost pressure we recorded baseline numbers of 423 HP and 409 TQ measured at the wheels.  A simple Stage 1 calibration with 93 octane fuel in the tank took the GTS to an astonishing 506 HP and 488 TQ measured at the wheels, peak gains of over 19%!
