BorgWarner 12747100010 EFR 9174 Turbocharger SuperCore Aluminum Bearing Housing

The BorgWarner EFR 9174 SuperCore with aluminum bearing housing is an advanced high-performance turbocharger cartridge designed for racing and extreme performance applications producing 600-1000 horsepower. This hybrid turbo combines the turbine from the 8374 with the compressor from the 9180, creating an optimal balance of power and response for demanding builds.

Key Features:

• High-flowing 91mm compressor wheel paired with fast-spooling 74mm turbine wheel
• Maximum turbo speed of 125k RPM for extreme boost and high-altitude applications
• Lightweight aluminum alloy bearing housing derived from IndyCar technology
• Gamma-Ti (titanium aluminide) turbine wheel for quick boost response
• Dual-row ceramic ball bearings with built-in oil control orifice - no external restrictor needed
• 68mm compressor wheel inducer, 91mm exducer
• Capable of 95 lb/min airflow and 45+ psi boost

The EFR 9174 SuperCore is sold as a cartridge assembly and requires separate turbine housing, clamp hardware, and wastegate components. Intended for applications that will push a turbo to the limit with high boost and critically high turbo shaft speed, this turbocharger delivers championship-proven technology for the most demanding performance builds.
