To construct a pair of TTE1000 VTG they take Gen 2 turbo's and change the original compressor and employ a far larger and more efficient billet wheel and mill the compressor cover to the optimum gap to match the new compressor profile and add 70mm billet bell mouth intake. They also fit larger 9 blade turbines and TTE High-Flow VTG mechanism for greater flow and lower exhaust gas temperatures.
Precisely balanced 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, 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 TTE's 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.
991.1 TURBOCHARGERS CAN NOT BE UPGRADED TO TTE1000 VTG. ONLY GEN 2 TURBO S TURBOCHARGERS CAN BE UPGRADED TO TTE1000 VTG
FOR 991.1 YOU MUST BUY NEW OR SEND GEN2 TURBOCHARGERS FOR UPGRADING TO TTE1000 VTG
