These units offer our only turbocharger step to increasing your 4.2 TT V8 performance, yet offer near no loss in response over stock. Very popular with owners wanting RS6 Plug & Play fitting units but with greater and wider performance, still keeping OEM drivability.
Engineered & Enhanced
TTE650 Turbochargers start life and evolve from Genuine RS6 K04 OE units, we then fit bigger and better billet compressors mated to clipped turbines. Engineered and enhanced using only BorgWarner components.
Performance with Durability
TTE650 compressor covers are CNC machined in house to an optimum clearance to allow fitment and maintain the efficiency of a larger more advanced billet BorgWarner 2283 Extended tip compressor wheels.
The 2283 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 with less heat for powerful top-end performance.
Turbine and shaft remain stock K04 items apart from a special curved clip process we perform. A TTE curved grinding process to the turbine blade tips, curved to alleviate stress from the process. Clipping reduces blade area thus increasing gas flow and so reduce back pressure and lowering exhaust gas temperatures, allowing safer higher boost level’s. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing the rotational mass improving moment of inertia.
Special profile 360 deg high performance motorsport BorgWarner journal bearing are fitted, to remain durable at higher loads with no loss in transient response.
Actuators used are uprated sprung OE units fitted with our reinforced clamps for trouble free operation.
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.
