The Ford Shelby GT350 and GT350R Mustangs, renowned for their track prowess and distinctive flat-plane crank Voodoo V8 engine, have ceased production. However, at Hennessey Performance, the legacy of these exceptional machines continues to thrive. We remain dedicated to enhancing the already impressive platform of the GT350, offering upgrades that unlock its full potential, regardless of Ford’s production conclusion.
From the factory, the Shelby GT350 and GT350R boast a formidable 526 horsepower and 429 lb.-ft. of torque. Recognizing the untapped reserves within this remarkable V8, Hennessey developed a supercharged 850-horsepower upgrade for the 2018-2020* Shelby GT350 and GT350R models. This transformative enhancement elevates the stock figures to a staggering 850 horsepower and 673 lb.-ft. of torque. This substantial 40% power surge transforms the already track-capable car into an entirely new beast, all while preserving the iconic characteristics and functionalities that define the Shelby. The supercharged Shelby GT350 Mustang retains its class-leading 8,250 RPM redline, along with all original mechanical and driver-controlled track electronics, ensuring an uncompromised driving experience.
The Shelby GT350 has rightfully earned its reputation as Ford’s premier track-focused Mustang, strategically positioned above the Mustang GT, GT Performance Package, and Mach 1. While those models utilize the 5.0L Coyote V8, the GT350 distinguishes itself with the unique 5.2L Voodoo V8 engine. The GT350R further amplifies track capabilities with specialized components such as carbon-fiber wheels and a prominent carbon-fiber rear spoiler, contributing to weight reduction and enhanced downforce. Both GT350 and GT350R models are equipped with high-performance Michelin Pilot Sport Cup 2 tires and Brembo brakes, featuring 6-piston calipers in the front and 4-piston calipers in the rear. Notably, the carbon fiber wheels on the ‘R’ variant contribute to a significant weight saving of approximately 60 lbs compared to the standard GT350 wheels. Additional track-oriented features of the ‘R’ model include a larger front splitter and the deletion of the rear seat, reinforcing its dedication to track performance. Exclusively available with a Tremec TR-3160 6-speed manual transmission, both models deliver a purist driving experience.
Hennessey’s supercharged 850 horsepower upgrade is a comprehensive system, featuring a 3.0L roots-style supercharger, an upgraded throttle body, high-flow fuel injectors, a performance air intake, a new heat exchanger, and meticulously calibrated engine management software. Each Hennessey GT350 and GT350R upgrade is distinguished by unique exterior and interior badging, along with a serialized engine plaque, signifying its exclusive nature. This upgrade not only amplifies the Shelby GT350 Mustang’s track prowess but also enhances its overall performance profile. From improved 0-60 mph acceleration to a significantly broadened power band, the supercharged 5.2L V8 engine truly awakens the car, achieving performance levels that rival even the formidable Shelby GT500. To provide owners with confidence and assurance, Hennessey’s supercharged 850 horsepower upgrade for the Shelby Mustang is backed by an industry-leading 2-year / 24,000-mile limited warranty.
For those considering the supercharged Shelby GT350 Mustang as a weekend track companion, a thrilling daily driver, or a prized collector’s item, it stands as a guaranteed future classic.
