Introducing our TTE280 performance turbocharger for the 1.8T VAG longitudinal platform.
Engineered & Enhanced
To produce our hybrid K04 TTE280 upgrade turbocharger we use a much larger BorgWarner 2283 billet compressor wheel, chosen because it is highly efficient and features BorgWarner Extended tip technology, creating an extremely high flow for comparative size, but giving a compressor map that’s very wide.
The intake to the compressor wheel is CNC milled billet and hand polished to smooth the transition from the intake pipework to the larger compressor to lower turbulence and maximize velocity. We CNC profile the billet intake and fit to the compressor cover and set to an optimized tolerance/gap to ensure maximum compressor efficiency is given.
We CNC re-profile the exhaust turbine housing and port the exhaust outlet to accept a larger K04 turbine and shaft, a BorgWarner item, that we give a special curved clip of a specific amount. The clipping is a TTE grinding process to the turbine blade tips, curved to alleviate stress from the process. Clipping reduces blade area, increasing gas flow and so reducing 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 rotational mass, improving moment of inertia.
Special profile 360 deg high-performance BorgWarner motorsport journal bearing is fitted, to remain durable at higher loads with no loss in transient response. The actuator used is uprated sprung BorgWarner unit.
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.
