- Turbochargers to boost General Motors' Chevrolet Corvette ZR1
featuring 5.5-liter flat plane crankshaft V8 engine
- Turbochargers utilize patented decoupled ball bearing system,
enabling faster response time, higher durability, and limited
noise
- Long-standing reputation with NTT INDYCAR SERIES played role in
selection
AUBURN
HILLS, Mich., Sept. 23,
2024 /PRNewswire/ -- BorgWarner, a global product
leader in delivering innovative and sustainable mobility solutions,
has solidified an agreement to deliver its turbochargers for use on
the General Motors Corvette ZR1 sports car platform, marking the
largest passenger car twin turbochargers in the market to be
released to date. Paired with the automaker's 5.5-liter flat plane
crankshaft V8 engine, this "unthinkable" Corvette is capable of
1,064 horsepower and 828 pound-feet of torque.
The automaker selected BorgWarner's twin ball bearing
turbochargers as a result of the company's extensive work and
reputation with the NTT INDYCAR SERIES and ability to provide
turbochargers that function at the highest levels. The
turbochargers feature a 76mm forged milled compressor wheel with
ported shroud and a 67mm turbine wheel inside a mono scroll turbine
housing for maximum efficiency. The turbocharger integrates an
exhaust manifold with equal length runners to amplify engine
performance and better tune noise.
"We are proud to secure this contract and support General Motors
in making the most powerful Corvette ever built. This technology
has been in the works for some time now and to see it come to
fruition is both exciting and fulfilling," said Dr. Volker
Weng, Vice President of BorgWarner Inc. and President and General
Manager, Turbos and Thermal Technologies. "BorgWarner
and General Motors have a long history of producing market-leading
applications across a wide range of segments, and we look forward
to continuing to develop new technologies and push industry
boundaries together."
The new turbochargers also contain a compressor-mounted blade
pass speed sensor, allowing General Motors to accurately monitor
how quickly the turbo is operating, enabling the vehicle to utilize
100 percent of its turbo capabilities without compromising the
integrity of the part. Additionally, the technology incorporates a
patented decoupled ball bearing system capable of a faster
response time than traditional journal bearings, all while limiting
noise transmission and maximizing durability.
Designed and manufactured in the
United States, the turbochargers are designed to withstand
extremely high temperatures with zero-clearance heat shielding on
the turbine housing to improve thermal efficiency and prevent
excessive engine compartment temperatures. They also feature an
electronically actuated wastegate system that enables General
Motors' anti-lag calibration.
The turbochargers have a small Gemini rocket insignia cast on
the face, paying homage to General Motors' history with NASA's
Project Gemini missions in the 1960s and the astronaut's
relationship with the Chevrolet Corvette.
