TTE900M+ Upgrade Turbochargers For BMW M5/M6 (S63)

TTE900M+ hybrid performance upgrade turbochargers based on the Original twin-scroll turbochargers for the twin-turbocharged 4.4 V8 BMW engine. Stage 3 power, with great spool and response. 

Engineered & Enhanced  

To construct these upgrade turbochargers 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 the optimum gap to match the new compressor profile and fit our CNC billet 76mm intakes. We replace the original turbines 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 a TTE upgrade bearing.

The 9 Blade TTE turbines are 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.

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 the 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.
