Porsche 991.2
In the coming months we'll be developing our Accessport and Accesstuner tuning solutions for Porsche's newest Carrera. Fun fact – IT HAS TURBOS!
The 2017 Carrera S marks Porsche's first turbocharged non-Turbo model Carrera S. The outgoing 3.8L naturally aspirated motor is replaced with a smaller 3.0L motor with two turbochargers bolted to the sides. Porsche's reasoning behind the switch is to improve both power and economy without sacrificing the core benefits of the Carrera and Carrera S. There are, of course, may opinions on whether or not they've succeeded in that venture. We'll save that for another time and focus simply on the differences in power output between the old and new.
2015 (991) Carrera S
The outgoing Carrera S was equipped with a naturally aspirated 3.8L engine that produced around 369hp and 309 ft/lb measured at the wheels. Displayed in the dyno graph below, the torque curve was (relatively) flat across the board with a steadily increasing horsepower curve. This is a motor that loves to live above about 5000 RPMs. Also obvious is how high-strung these motors were from the factory. While there are definitely gains to be had with bolt-on modifications and tuning, they are not anywhere near what we typically see with a turbocharged application.
2017 (991.2) Carrera S – Baseline Dyno Pulls
Below is an initial baseline from our 2017 Porsche Carrera S. Immediately noticeable is the sharp low-end torque curve which reaches peak almost immediately and carries to right at 5000 RPMs. This car is making about 10 wheel horsepower and 70 wheel torque more than the outgoing Carrera S. The additional low-end torque is hugely present while driving and makes the Carrera S a pleasure to scoot around town. Power is still very strong up top approaching the 7400 RPM redline. We are extremely excited to dig into Stuttgart's newest Carrera and have high hopes for their future turbocharged vehicles.
Our engineering team had the pleasure of disassembling a brand new Porsche. Along with increasing power output through tuning, we'll be determining an ideal upgrade path based on what parts are found to be a limitation to making additional power.
