Porsche 991.2 Power Gains with Accessport Tuning
After more than two years since we first took delivery of our 991.2 Carrera S and dove in head-first, we can finally see the end of the tunnel. Not just the spec of light coming from it, actual daylight. And it is glorious. With the release of the COBB Accessport for Porsche’s 991.2 Carrera and Turbo/Turbo S imminent, we wanted to share some exciting data from our development period. Most notably, how much power these cars make! Below we’ll give a brief synopsis of the power gains 991.2 owners can expect when they choose the COBB Accessport as the tuning solution.
991.2 911 Carrera
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.

991.2 911 Carrera S

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.


991.2 911 Carrera GTS

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%!

991.2 911 Turbo / Turbo S

This is where the fun really starts. The 991.2 911 Turbo’s 3.8L powerplant with VTG turbochargers is rated at 540 HP, and the Turbo S, with it’s larger turbochargers, at 580HP. We recorded 493 HP and 485 TQ at the Turbo’s wheels in true factory-form. The final version of our Stage 1 Off The Shelf Map increases that to 538 HP and 591 TQ to the wheels.

The Turbo S managed to spin the dyno to the tune of 524 HP and 543 TQ at the wheels. After some calibration magic, the Turbo S was scorching the dyno rollers to the tune of 594 HP and 639 TQ measured at the wheels.
