TTE470 Upgrade Performance Turbocharger VAG 2.0TFSI EA888 Gen 3 – IS38
TTE470 is our hybrid performance upgrade turbocharger for the new 3rd generation VAG 2.0TSI following on from our proven TTE400+ upgrade stage. Fast boost response near like as a stock turbocharger but with durability and higher power.

Engineered & EnhancedTo construct a TTE470 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 CNC modify original compressor cover and delete the DV function and port right before the compressor wheel to improve efficiency and power for increased airflow and CNC modify the compressor cover to vent to the atmosphere.

We also fit our TTE CNC silencer delete. Modifying the turbo discharge silencer, removing the baffle internals and fitting a new straight through section, removing any restriction and its function as a noise cancelling device, and so improving the flow, giving less surge and enhancing the sound.
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 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 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.
