Tech Session Recap: Growler Motor Labs By Peter Wen uning is the simplest and the most cost effective way to improve the performance T of your Porsche. When the opportunity became available to get my car tuned and dyno’d at Growler Motor Labs, I didn’t think twice. Growler Motor Labs specializes in Cobb Tuning, which is unique from other tuning products in the marketplace. With its proprietary Accessport device, you can easily modify your Porsche’s ECU by simply uploading different maps. Plug the Accessport unit into the car’s OBD-II port and you are good to go; no need to remove the ECU or visit your mechanic. Currently Cobb makes Off-The-Shelf (OTS) maps for certain models of Boxster/Cayman, 996/997/991 Turbos, and Macans. If more power is desired, OTS maps can be fine-tuned (called ProTune) for your specific Porsche! This process is also 100% reversible, since the Accessport saves a copy of the original Porsche map during the initial synch. During the tech session, my Porsche completed three dynamometer runs. The first run established the baseline of the car’s performance. We then installed the OTS map and ran the dyno again. After the second run, with the OTS dyno data in hand, the Growler technician, Grant Tillman, expertly “tuned” the OTS map and created a custom ProTune map for my car. After that was installed, we ran the dyno for the third time. Before I get to the results, I must confess, I was a nervous wreck during those dyno runs. Like an expectant father, heart racing, palm sweating, I paced the shop floor. My car was strapped down securely on the all-wheel drive Mustang Dynamometer. After a brief warm up, it was eased to around 2,000 rpm, then Grant floored it all the way up to 6,700 rpm just before the redline. The computer captured all telemetry data from the ECU during the run, including horsepower and torque stats. Photos by Jim Hirsch Standing next to my Turbo S while running pedal-tothe-metal was a surreal experience. The sound coming off the 3.8 liter flat 6 with twin turbochargers was like a jet plane taking off. During the rapid acceleration, the car emitted intense heat waves that sent all spectators back a step or two. Once it surpassed 6,000 rpm, it was so incredibly loud and intense that I felt I should kneel and pray for my baby. The results were impressive. Power increased 8% with the OTS map and 10% with the ProTune, to 530 WHP (wheel HP). With the estimated 19% drivetrain loss, the estimated crank HP was actually over 650 (BHP)! Torque had even more impressive gain from the tune: 9% with the OTS and 13% with the ProTune to 573 (ft-lb), a gain of 67 ft-lb! With this much gain in power and torque easily accessible starting at 3,000 rpm, the driving dynamic (fun factor) improved drastically. Like Jeremy Clarkson from Top Gear, I too wanted to shout: “More Power!” My Turbo S felt like a new car. Drive it normally, there’s no difference. However, when you push it, a new beast emerges. The best part? The car still has the same smooth and quick PDK shifts that we all know and love. Sport and Sport Plus modes all continue to work, albeit with more urgency and aggression. Launch control? Yep. Step aside Tesla, this is the new ludicrous-mode! I absolutely love the tune. It makes an incredible car even better. Pound for pound (or dollars in this case), this is one heck of a mod. I am so pleased with the results. Oh, and one unexpected and unconfirmed benefit: better fuel economy! Can this really be true? More power and better MPG? Somebody pinch me! Editor’s Note: Chris Sorrells also brought his 2017 Macan S to this tuning session and had similar improvements in performance numbers.
