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. TTE550 Turbochargers start life and evolves from Genuine RS4 K04 OE units that are Engineered. These units offer you more performance yet offer little 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 near OEM drivability.
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 an exducer of 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 maximize performance.
The TTE 2280X compressor wheel design features promote greater airflow using a low inertia wheel that performs like a wheel of even greater size and mass using BorgWarner geometry. 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. We CNC mill the turbine housings to a bigger size and replace the standard BWTS K04 Turbine and shaft for the Larger TTE 9 blade turbine for increased flow and power. The 9 blade turbine reduces the back pressure and lowers exhaust gas temperatures, allowing safer higher boost levels. This lower blade count 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 is 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.
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 the 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 a serial numbered balance test result document.
If you chose to upgrade your existing turbo, our sales staff will reach out to you after placing the order to arrange shipping and discuss timeframe as well as other details. Please note that miscellaneous charges for logistics and VAT may accrue.
