BorgWarner introducing next generation EFR turbocharger
24 October 2012
BorgWarner will introduce its next-generation EFR-7163 (Engineered for Racing) turbocharger as well as its current EFR and AirWerks Series turbochargers at the 2012 SEMA Show at the Las Vegas Convention Center. Featuring an innovative light-weight aluminum bearing housing and mixed-flow turbine, BorgWarner’s new EFR-7163 turbocharger achieves up to 550 hp 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.
SEMA visitors can view BorgWarner’s new EFR-7163 turbochargers in a 2013 Ford F-150 FX4 SuperCrew pickup powered by an EcoBoost 3.5-liter engine and a 2009 Jeep Wrangler Unlimited driven by a Cummins 6B diesel engine.
