![]() Both of the cars tapered at the same point which leads me to believe they were restricted from lack of airflow. Horsepower increased from 3500rpm with a gain of about 40awhp holding an increase to about 6000rpm where it tapered off. When looking at the graph, the 991 Turbo made 43 more ft/lbs of torque and held a solid torque gain all the way to redline. Our 991 Turbo made 525ft/lbs of torque and 493 awhp. We ran the same sequence of 3 runs and like the Turbo S, the first was the best. Both being run in Standard Mode, both with 91 octane, both with the same dyno settings and calibration. Strapping our old Project 991 Turbo down, we would get a good Apples to Apples comparison. Now to reiterate, both these cars had the same Agency Power add-ons except the Turbo S had straight pipes and highflow cats with a GIAC tune. Expecting more power, I told the customer, “wait let me dyno my old 991 one right now to see where it is at.” Since the car was here, it was a perfect opportunity. This would mean the car is making about 615hp to the crank up 35 from the stock 580hp. Running the Turbo S on our Mustang AWD Dyno with 91octane and a temperature of 100F, we typically see a 20-25% drivetrain loss. Our first run in Standard Mode was our best with a peak torque of 482 ft/lbs at about 3500rpm and 474 awhp at redline. Each run the car would lose more performance because of the increasing temperatures. We ran the car with our first run on a cool car in standard, then ran a sport run, and finally a standard run. After installation and some test driving, we decided to do some dyno runs of the car. So to improve the cars low end torque and throttle response, we added our Agency Power intakes, Y-Pipe, and headers to the car. The car already had a GIAC ECU Tune, Sharkwerks muffler bypass pipes and high flow cats. ![]() ![]() Porsche’s S version came equipped with 580 horsepower, which already gave it a 60hp advantage over our 991 Turbo. Already equipped with the AP Y-Pipe, Intakes, Headers, Exhaust, and VR Tuned box, the new owner chatted his buddy up to come to Vivid Racing for similar mods on his 991 Turbo S. Having sold our 991 Turbo in April 2015, it circled back to us for some product development. With these proven results, many customers picked up on our parts and had a go for themselves. Combined with our Agency Power products, we added almost 100 horsepower to the crank. Tapping into the cars sensors, the tuning box gave the 520 horsepower 911 about 60whp and 80ft/lbs gain over stock. Because the ECU could not be read out due to tuning encryption, the only option was the VR Tuned Tuning Box kit which is a plug and play solution. But it was not until August 2014 that we had a tuning solution to really maximize the performance of our 991. Developing headers, an exotic sounding exhaust, high flow y-pipe, and intakes for it were just the start. When we got our 2014 Porsche 991 Turbo in December 2013, we went right to work with modifying it. Many dyno test, installation articles, opinion notes, photos, have been done on the likes of our Porsche 996TT, 997TT, 997.2TTs, 997GT3RS, and now our 991 Turbo. We have been apart of the Porsche tuning community since 2005 and have definitely had our fair share of fun with cars.
