It is TTE8XX Upgrade turbochargers for the new 4.0L TFSI displacement motor.

Still keeping the original turbocharger turbines but clipping the original blades for greater flow and to lower exhaust gas temperatures. We fit a bigger 6+6 blade milled BorgWarner billet compressors so producing extra power but focused on response.



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 a serial numbered balance test result document.
