Product information "TTE440L 2.0 TSI UPGRADE TURBOCHARGER"


 AUDI A4 B8.5 B9, A5 B8.5 B9, A6, Q5, Q7 2.0 TSI/TFSI 

TTE440L is our very latest hybrid performance upgrade turbocharger based on the Original IHI turbocharger for the 3rd generation VAG 2.0TSI found in the AUDI A4 B8.5 & 9,  and many other VAG cars.  Stage 3 hybrid power, with amazing spool and response. We feel this is the best performing plug & play hybrid available on offer today.

Engineered & Enhanced  EA888 Gen 3 

To construct a TTE440L 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 an optimum gap to match the new compressor profile. We replace the original turbine and CNC mill the turbine housing to install a larger lightweight 9 blade turbine for greater gas flow. We also replace the original thrust bearing for TTE upgrade 360 deg that is made in-house. 

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

The 9 Blade TTE turbine is a special turbine designed by TheTurboEngineers.  Advantages are greater gas flow, reducing back pressure and lowering exhaust gas temperatures, allowing safer higher boost levels. This turbine is extremely light in mass so giving a reduced moment of inertia, meaning fast spool up for the size.



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.
