2020 Mustang Shelby GT500 Already Tuned to 720 Horsepower You can make real world gains by making a few modifications. The 2020 Mustang Shelby GT500 is Ford’s most powerful V8 engine. It produces 760 horsepower (567kilowatts) as well as 625 pound-feet (847 Nm) of torque. This engine is close to the Dodge Challenger Redeye with its 797-hp (594kW) powerplant. It’s not something that many Mustang owners do. One has to head to Palm Beach Dyno to get more power and baseline testing. This video shows how simple modifications can make your vehicle more powerful. The video begins with a baseline pull of the car stock. The car produces 664 horsepower (494 kW) at its wheels, which is a 13. percent power loss. The shop then installs the K2 air filter in order to determine if there are any gains. This is where the video explains how to read dyno charts. One pull showed a significant increase in torque while the other pulls had negligible gains. The 93 octane tune offers greater gains. The tune’s first set of dyno runs returned 703 horsepower (524 kW) & 577 lb/ft (782 Nm). This is a significant increase in power over the stock car. The Shelby can make even more power if the rev limiter goes from 7,500 to 8,000. The GT500 generates 720 horsepower (536 kW) as well as 579 lb.ft (785 Nm), when the rev limiter is raised.
