PORSCHE 911 TURBO S / COBB / DYNO ARCHIVE

Two Turbo S projects.
Results with context.

I calibrated these 2014 and 2018 Porsche 911 Turbo S models through COBB during my work at AWD Tuning. Their dated Mustang Dynamometer reports document two separate cars and sessions.

2014 Turbo S: a same-day comparison.

510.0 hpBaseline peak
543.0 hpRevised-tune peak
+33.0 hpDifference in peak output

The April 17, 2019 reports record a baseline peak of 510.0 hp and a revised-tune peak of 543.0 hp. Both belong to the same day’s session. The peak values occur at different engine speeds, so the 33.0-hp difference is not a gain measured at one fixed RPM.

2014 Porsche 911 Turbo S peak horsepower comparisonApril 17, 2019 Mustang dyno reports: baseline 510 horsepower; revised tune 543 horsepower. Bars start at zero and use the same scale to 600 horsepower. These are separate peak values, not full power curves.Recorded peak power (hp)Baseline510Revised tune5430600 hp
2014 911 Turbo S · April 17, 2019 · Corrected Mustang chassis-dyno peak values. A 33 hp increase in recorded peak output; the bars do not reproduce the full power curves.

The comparison is useful because it documents this car’s baseline and revised calibration together. It does not establish the same gain for every Turbo S or an identical hardware-and-fuel comparison for another car.

2018 Turbo S: 624.9 hp on 93 octane.

A separate April 6, 2026 report records 624.9 hp at 6,292 rpm for the 3.8-liter 2018 Turbo S. I tuned this car through COBB on 93-octane fuel. It is a different project from the 2014 car, not the next step in that car’s development.

What I want from the calibration.

Peak output is one part of the brief. I also care about transient throttle response, the relationship between pedal input and boost, and power delivery the driver can use with confidence. Those priorities guide the discussion about a road car or a competition setup.

Most of these Porsche projects used bolt-on upgrades. The exact parts lists for these two cars are not recorded here. For your tune, I start with your car’s hardware, fuel, condition and goals.

How to plan your own 911 tune.

  1. Send the model year, generation, trim and market.
  2. Include your Accessport details, current calibration, fuel and modifications.
  3. Tell me whether you want remote support or a coordinated dyno session. Engine and PDK support are checked separately.

About the records.

Source: my original AWD Tuning Mustang Dynamometer reports dated April 17, 2019 and April 6, 2026, together with my firsthand account of the COBB calibration work. Figures are chassis-dyno peaks with the reports’ WCF correction, not factory crankshaft ratings. Dyno conditions and the complete vehicle specification affect output.
