Eaton unveils new supercharger for 2020 Shelby GT500

The US-based power management company Eaton unveiled the TVS R2650 supercharger to help boost the hand-built and Ford Performance-tuned, 5.2-liter V8 engine that powers the all-new 2020 Shelby GT500.

The new supercharger is the evolution of the Twin Vortices Services (TVS) platform, which features a patented rotor coating for improved efficiency. The high-twist, four-lobe rotor design in the new TVS R2650 is 15 percent larger than the TVS 2300 supercharger found on the previous Shelby GT500 and features several improvements to maximise efficiency and improve performance at higher speeds. The Eaton TVS R2650 supercharger in the all-new Shelby GT500 provides up to 12 psi of boost, helping to produce 760 horsepower and 847 Nm of torque. Eaton claims that these figures makes the 2020 Shelby GT500 the most powerful street-legal Ford ever and the most power- and torque-dense supercharged production V8 engine in the world.

Eaton further reveals that several technical modifications help this supercharger deliver supercar-level power and torque, including a 170-degree helical twist of its rotors, which is 10 degrees greater than previous TVS rotors. Other upgrades include bearing plate pressure relief points that reduce trapped volume pressure and optimized sealing for better flow efficiency.

The 2020 Mustang Shelby GT500’s engine is hand-built at the Ford Motor Company’s Romeo Engine Plant in Romeo, Michigan, and its innovative TVS R2650 supercharger is assembled at Eaton’s Vehicle facility in Athens, Georgia.

Karl Sievertsen, chief technology officer, Eaton’s Vehicle Group said, “We are proud to collaborate with Ford Performance to help it produce the most powerful Mustang and street-legal Ford ever.”

While Eaton’s TVS technology has long provided boost to high-performance vehicles, the technology also is used for advanced combustion engines, providing transient response with precisely metered air flow at any engine operating condition, independent of exhaust gas enthalpy. This is critical for new engine concepts, where high levels of air are often required at operating points at which turbochargers are limited.

The positive-displacement TVS technology provides the required airflow conditions precisely and instantaneously and can also deliver an additional boost in power. TVS technology can be driven mechanically or electrically, providing flexibility for automakers as Eaton looks to a more electrified future. TVS technology also is used in hydrogen fuel cell applications, as this technology often requires high levels of pressurised air at certain operating points.

Eaton claims that its TVS technology goes beyond automotive applications, enhancing performance in the personal watercraft industry and providing accurate airflow in industrial applications.
