    BorgWarner EFR8474 Super Core - Iron

    $3,517.85
     
     
    This item is a recurring or deferred purchase. By continuing, I agree to the cancellation policy and authorize you to charge my payment method at the prices, frequency and dates listed on this page until my order is fulfilled or I cancel, if permitted.

    Please Note:

    BW Supercore's do not come with clamp plates, bolts etc and an installation kit (Part # 179423) required to assemble turbo.

    The Borg Warner EFR8474 is a brand new release for 2019 and represents the state-of-the-art from BorgWarner Turbo Systems. This unique turbo was designed specifically by BW engineering to combine the high flowing 68mm compressor inducer with a low inertia (fast spooling) 84mm exducer to allow the same footprint to breathe a LOT better up top without compromising down low and midrange.  Efficiency plateaus are widened as a result.  RPM Capabilities have also been re-evaluated in which higher pressure ratios can be better utilized.That’s a 21.8% improvement in flow for a little bit of offset spool RPM, all on the same sized turbo!  Using the same 74mm Gamma-Ti turbine wheel from the EFR8374, this turbo flows an impressive 95lbs/min of air at the same 127k RPM maximum shaft speed.  EFR8474 is intended for applications which will push a turbo to the limit with high boost.  This hybrid turbo uses the lightweight alloy bearing housing derived from Indycar with an aggressive 68mm inducer compressor wheel.

    Compressor Specifications:
    Compressor Type: Forged-Milled Wheel (FMW) Extended Tip
    Compressor Wheel OD (exducer): 84mm
    Compressor Wheel Inducer: 68mm
    Max Flow Rate: 95 lb/min
    Built-in BOV: All EFR compressor housings incorporate an integrated compressor recirculation valve

    Compressor Housing Connections:
    Inlet: 4″ Ported Shroud Hose Coupler
    Outlet: 2.5″ Hose Coupler w/ integrated Vband option

    Using Borg Warner’s 84mm FMW compressor (68mm inducer) the 8474 houses our traditional 7 blade EFR extended-tip compressor wheel design capable of 95 lb/min airflow rate. Ceramic Ball Bearing only, watercooling optional (recommended). We strongly recommend using an EFR Speed Sensor if you plan to run to the limit.

    Turbine Specifications:
    Turbine Type: Low Inertia Gamma-Ti Turbine Wheel
    Turbine Wheel OD: 74mm
    Stainless Steel Turbine Housing
    Turbine outlet: GT V-Band (aka 3″ V-Band) ~92mm OD for all EFR turbos

     

    Super Core Assembly Does NOT Include:

    • Turbine Housing
    • Assembly Clamp Plate Hardware
    • Wastegate Parts
