Baseline Dyno Pulls : 2017 Porsche 718 Boxster S


Porsche recently released it’s newest iteration of the Cayman/Boxster line, dubbed the 718.  A major change from the previous 981 chassis cars is the introduction of turbocharged power plants.  Cayman and Boxster base models will receive a 2.0L Turbocharged 4-cylinder engine where the ‘S’ models receive a 2.5L Turbo 4.  Being horizontally opposed, or ‘flat’ for short, the motors do take on a familiar exhaust note due to exhaust routing.  Since picking the car up last week, we’ve put nearly 1000 miles on it by way of some wonderful Central Texas hill country.  With the engine broken in, it was time to hit the rollers to see what kind of power our Boxster S is putting to the ground, and the results may be surprising.

718 Stock Baselines

In the dyno graph above, the Red line represents the car in Normal mode.  The Green line represents Sport Plus, and the Blue line represents the car being in Sport Plus with Sport Response activated.  The main difference between the three modes is apparent in low-end torque.  Boost does appear to ramp in quicker with Sport Plus selected, and again-so with Sport Response active.  Beyond ~2700RPM boost remains constant and relatively flat throughout a pull.  While these torque numbers do indicate that Porsche may be a bit conservative with advertised power numbers, the most important data will be represented in gains from these baseline pulls.

We are obviously very excited to dive into tuning on Stuttgart’s newest machinery and have high hopes for it’s potential.  Stay tuned to the COBB Blog for updates!

  1. That makes some nice power. No shock there, but it will be so much cooler with more and some sound! Nice job guys.

    • Great question, it’s definitely a bit on the choppy side. Once we’re able to get into the ECU and look at some data of these pulls we will have a better understanding of how the car is working and what could be causing the torque curve to waver. I will say that the torque feels much smoother on the road than this graph would indicate.

      • The torque curve is outstanding based on my 2,900 miles of driving the new 718 Cayman S PDK super car. While I am interested in the tune, Porsche has been EXTREMELY conservative in reporting its performance. Car & Driver’s instrumentation testing resulted in a 3.6 0-60 mph. Automobile Magazine hit 186 mph on the Autobahn. This car is a rocket, and with the lowered chassis and 20″ turbo wheels, clings to the corners.

  2. Are you guys planning a remap for the base 718 model and if so what realistic bhp do you think is achievable thanks

  3. Any developments? Progress?
    Very interested in this as there’s no good solution out there right now for 718 tuning!

  4. If I could wager an amateur guess, I’d say the chopping torque curve is Porsche trying to make power easier to ‘meter’ out on the track by holding it back from the big surge’s of boost.

    Most who’ve given the 718 some track time have said that it doesn’t tend to surge and that power is surprisingly easy to meter for a turbo car. Makes it feel more like a NA car.

    • Hey Bryan, that is probably a pretty good guess into what is happening. We have actually been making some great progress with reverse engineering in the past few weeks and are learning a great deal about how this car works. Excited to show some preliminary power gains in the coming weeks. This car is going to be an absolute riot with some very simple tuning.

  5. What type of dyno is used? On dynojet my 718 Cayman S did 320 WHP. I am anxiously awaiting reflash the car is a blast to drive already I can’t imagine with 400 WHP.

    • Jeff,

      Our dyno is also a Dynojet. Seeing a modest variance in power from on different cars at different locations is pretty common, even on the same type of dyno. Especially with different fuel and atmospheric conditions. We’re still plucking away at the 718, stay in touch with us for more updates in 2018. – [email protected]
