TTE800 is our first hybrid performance upgrade turbocharger step for the 4.0 TFSI. Even more power, with great response as a stock turbocharger but with durability for higher boost
Engineered & Enhanced
To construct a pair of TTE800's we change the original compressor and employ a far larger and more efficient billet wheel with extended tip technology and mill the compressor cover to optimum gap to match the new compressor profile.
We install a clipped turbine for greater gas flow. The clipping of the turbine is a special TTE grinding process to the turbine blade tips. Curved to alleviate stress from the process. Clipping reduces blade area thus increasing gas flow and so reducing back pressure and lowering exhaust gas temperatures, allowing safer higher boost level. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing the rotational mass improving moment of inertia.
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.
