Performance Boost at a Lower Price

Roush Performance has unveiled an appealing supercharger package for the 2026 Mustang GT and Dark Horse, enhancing performance without the hefty price tag associated with factory models. Priced at $10,399, this supercharger kit increases the Mustang’s output to 810 horsepower and 630 lb-ft of torque, surpassing the factory-backed Mustang Dark Horse SC, which produces 795 horsepower and comes in at over $100,000.

Both the Mustang GT and Dark Horse models utilize a 5.0-liter Coyote V8 engine. The Dark Horse variant is tuned to deliver 500 horsepower, slightly more than the GT’s 480 horsepower. Despite the Roush kit’s higher horsepower figure, it generates 30 lb-ft less torque than the Dark Horse SC. Buyers can expect significant performance gains while still keeping costs below that of the high-performance variant.

Supercharger Specifications

The Roush supercharger is equipped with an inverted Eaton TVS R2650 supercharger, developed in partnership with Magnuson Superchargers. It boasts a “track-ready” cooling package and a fully upgraded fuel system capable of producing up to 13 psi of boost at 7,500 rpm. When installed on a stock S650 Mustang with slick tires, this setup enables the vehicle to accelerate from 0 to 60 mph in just 2.88 seconds and to complete a quarter-mile run in 10.33 seconds at an impressive 136 mph.

The Complete Package

While the Roush supercharger kit offers outstanding performance, the Dark Horse SC comes with additional enhancements, including improved bodywork and upgraded suspension components. Buyers interested in maximizing their track performance can opt for the Track Pack, which introduces specially calibrated dampers and lightweight carbon-fiber wheels equipped with carbon-ceramic brakes.

Despite these enhancements, Roush’s supercharger kit provides an economical performance upgrade, ideal for those eager to enhance their Mustang without extensive expenses. The installation process is streamlined, as it does not require removing the front fascia, and some custom-formed hoses are included for ease. Additionally, Roush backs the kit with a 3-year/36,000-mile limited powertrain warranty, ensuring peace of mind for enthusiasts looking to modify their vehicles.

With competitive pricing, substantial power gains, and a user-friendly installation, Roush Performance’s supercharger kit represents a noteworthy option for Mustang aficionados seeking to ramp up their driving experience.
