    TTE550 Upgrade Turbochargers RS4 / S4 / A6 2.7t

    The first TTE step to making your 2.7 TT motor shine. You the driver will feel RS4 K04 response with near RS6 unit power yet still keeping RS4 turbine housings. 550+PS capable.

    Engineered & Enhanced

    TTE550 Turbochargers start life and evolves from Genuine RS4 K04 OE units that are Engineered. These units offer you more performance yet offer near no loss in response over stock K04 once tuned with correct hardware & software. Very popular with owners wanting RS4 plug & play fitting units but with greater and wider performance to over 550PS but still keeping OEM drivability.

    See bellow for example of an RS4 K04 Stock car VS RS4 TTE550 Mrc stage 3 tuned.

    Performance with Durability


    TTE550 RS4 compressor covers are CNC machined in house to an optimum clearance to allow fitment and maintain the efficiency of a larger more advanced Billet 2280X Extended tip compressor wheels with inducer size of 45.1mm with a exducer 59.4mm Vs stock 2078 standard compressor with an inducer size of 39.9mm and exducer 51mm. We also as standard CNC mill the air inlet port on the compressor housing to remove a lip right before the compressor wheel to smooth the transition to the intake pipes to maximise performance.

    The 2280X compressor wheel design features promote greater airflow using a low inertia wheel that performs like a wheel of even greater size and mass. Extended tip technology enables the user to have faster spool-up at lower engine speeds while providing the boost for the powerful top-end performance.

    Turbine and shaft are RS6 size K04 items for increased flow and power so we CNC machine the RS4 turbine housing to suit the larger turbine used, tight tolerance is paramount here for overall performance. The turbine blades are also given a special curved clip. Clipping reduces the blade area thus increasing gas flow and so reduce backpressure and lowering exhaust gas temperatures, allowing safer higher boost levels. This process also gives a secondary advantage of removing some material mass, lightening the turbine thus reducing rotational mass improving moment of inertia.

    Special profile BorgWarner 360 deg high-performance motorsport journal bearing are fitted, to remain durable at higher loads with no loss in transient response.

    Actuators used are uprated sprung Genuine OE units fitted with our reinforced clamps for trouble free operation. These also can also be modified to customer needs and specifications.

    Equilibrium

    Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using our in-house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with serial numbered balance test result document.

    Key Points:

    Genuine BorgWarner Housings and key components
    TTE 2280X Billet compressor geometry
    CNC Ported compressor inlets
    Genuine BorgWarner Turbine shaft Trim 8 with clipped wheels (RS6 size)
    Genuine BorgWarner Reinforced Motorsport bearing system
    Genuine BorgWarner Modified reinforced and synchronised actuators
    Single parts finely balanced then components assembled and high-speed VSR balanced
    Supplied with a serial numbered balance test document for each turbocharger
    Installation as original RS4 K04
    550PS Capable
    Designed, Machined & Built by TTE in Germany

    Brand New Price 2940.34 Euro net

    To Recondition and upgrade a used set of RS4 K04 Price is 1763.87 Euro net

    (For customers in EU countries 19%+ VAT Must be added to prices above unless having a valid VAT ID)

    Shipping does vary but 45.00 euro is a good guide for Europe-wide.

    Reconditioning price shown is based on overhauling and reconditioning, upgrading an undamaged used turbochargers within specification. Only once cleaned and dismantled, inspected then a firm price be made

    Attention:

    These turbochargers use K04 RS4 B5 compressor housings and turbine housings, RS4 B5 specific turbo intake pipes are required for S4/A6 fitment.

    Optional Performance Extras

    CNC Ported exhaust entry (NEW) 500.00 Euro
    Lightened Turbine shafts 200.00 Euro
    Ported boost discharge outlet 150.00

    ITS ALL ABOUT THE FLOW.

    TTE CNC PORTED COMPRESSOR INLET

    Note: See the center hub on the billet TTE550 Compressor wheel. The Hub design bellow the nut is very slim and narrow to maximize the flow
