BorgWarner has introduced it's next-generation EFR-7163 turbocharger, featuring an innovative lightweight aluminum bearing housing and mixed-flow turbine, the new turbo combines the responsiveness and compact packaging of a B1 turbocharger with the greater flow capacity to achieve up to 550 horsepower.
"BorgWarner's latest EFR turbocharging advancements are built on our highly successful season as the exclusive turbocharger supplier for the IZOD IndyCar® Series. Our innovative technology optimizes responsiveness and maximizes power output, combining the best qualities of B1 and B2 turbochargers in a small, powerful package," said Pete Kohler, President and General Manager, BorgWarner Turbo Systems. "We are pleased to welcome Dario and the Borg-Warner Trophy to SEMA. Both symbolize achievement, competitive performance and technology leadership—the same qualities and spirit that drive innovation at BorgWarner."
Designed for powerful performance in a compact package, BorgWarner's new EFR-7163 turbocharger achieves up to 550 horsepower while using a small B1 frame size that fits easily into a tight engine bay. Track proven in the IZOD IndyCar Series, an aluminum bearing housing reduces the turbocharger's overall weight by approximately 2 pounds. For fast response, the 63 mm mixed-flow turbine features lightweight Gamma-Ti material and innovative geometry to increase turbine flow capability while providing lower inertia than a conventional radial-flow turbine wheel. To provide the best balance of quick response at low engine speeds with high flow capacity at top engine speeds, BorgWarner engineers optimized the 71 mm (OD) compressor wheel to manage as much flow capacity as a larger conventional wheel. For added flexibility, the turbine housing accommodates either a v-band or T25 inlet connection option for engines using an open manifold or a T4 twin scroll housing for engines using a divided manifold.
BorgWarner's new EFR turbo will be making it's way to Treadstone in the next few months and will be available soon.
