Product Description

The BorgWarner 12807100005 EFR 9280 Super-Core is a high-performance turbo core built for custom and high-boost applications. Featuring a forged-milled compressor wheel with a 73.7 mm inducer and 91 mm exducer, paired with a robust turbine wheel measuring 80 mm in both inducer and exducer, this assembly delivers rapid spool and exceptional flow. The integrated dual ceramic ball bearing assembly ensures reliability during sustained high-pressure operation, and the pre-tapped compressor cover simplifies sensor and boost line integration.

As a super-core unit, the 12807100005 provides unmatched flexibility - builders can select turbine housings tailored to their setup requirements. The kit includes all mounting hardware, though turbine housing, actuator, and V-band clamp are not provided and must be selected separately. Ideal for both gasoline and diesel performance engines, it supports approximately 1,100 HP (flywheel) when configured correctly. Trust in BorgWarner's proven EFR platform for your next serious build.
