Building on A Tradition of Excellence, Eaton Superchargers Surge Ahead In Power
And Performance

SOUTHFIELD, Mich. … Eaton Corporation’s new Twin Vortices Series (TVS) supercharger is a
“game changer” in the field of boosting technology, and the latest innovation from a company that
has been a leader in developing Roots-type superchargers for original equipment manufacturers
(OEM) and aftermarket applications for nearly 60 years.

The TVS’s patented new design features four-lobe rotors and high-flow inlet and outlet ports that
greatly enhance thermal efficiency, enabling greater volumetric capacity at higher revolutions per
minute (RPM). This means the supercharger effectively packs a bigger supercharged punch in a
smaller or equal-sized package, when compared with previous superchargers. It broadens the
performance range of the supercharger across an engine’s rpm range.

All new Eaton superchargers will feature the TVS design. In addition, as with Eaton’s previous
superchargers, the new TVS supercharger is scalable and adaptable to almost any engine.
“The TVS technology compares very favorably to other aftermarket boosting technologies and we
plan to launch the TVS in the aftermarket first, allowing the true enthusiast access to our latest
technology and the best available performance in the market,” said Jeff Romig, general manager,
Eaton’s Performance Products division.

The TVS supercharger is Eaton’s best, and builds on the outstanding performance of several
generations of Eaton superchargers that have improved steadily in the areas of efficiency, noise
reduction and durability.

Eaton’s first generation supercharger debuted in 1989 on the Ford Thunderbird Super CoupeTM.
Over the next decade, Eaton continued with design, performance and noise, vibration and
harshness (NVH) improvements in its second and third generation applications. The Ford Lighting
SVTTM and MINI Cooper STM used Eaton’s fourth-generation supercharger and introduced a
patented island bearing plate port configuration, which improved noise and vibration

In 2001, Eaton’s fifth-generation supercharger was made even better with the introduction of a
patented abradable powder coating to increase volumetric efficiency, and a patented integral shaft
bearing, which provided a packaging and cost improvement. Among the vehicle applications for
the Eaton’s fifth-generation supercharger are the Volkswagen Golf GTTM, Saturn Ion RedlineTM,
Ford Mustang Cobra SVTTM, Shelby Mustang GT500TM, Chevrolet Cobalt SSTM, Cadillac STS-VTM,
Cadillac XLR-VTM, Jaguar XKRTM, and Range Rover SportTM.

“The new TVS supercharger is a continuation of Eaton’s heritage of delivering innovative ideas and
performance to the automotive enthusiast,” said Romig. “The performance aftermarket segment is
demanding more – more power, more boost and more performance. And the TVS is further proof
that we’re ready to deliver.

“As a company, we’ve been doing it for nearly 100 years,” said Romig.
