PORSCHE 991.1 TURBO TTE850 VTG UPGRADE TURBOCHARGERS
Welcome to our TTE850 VTG Stage for the 3.8-litre flat 6 engine. To construct a pair of TTE850 VTG we change the original back plates for Gen 2 and Gen 2 compressor covers and employ a far larger and more efficient billet compressor wheel and mill the newer Gen 2 compressor covers to the optimum gap to match the new compressor profile. The turbines are original but with clipping of the blades for greater flow and lower exhaust gas temperatures and also removing some mass to help improve response and we also CNC mill the exhaust housings to improve flow.
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 a serial numbered balance test result document.

Sending Your Turbocharger
You are responsible for sending your turbo, follow the instructions below.
Be sure to place your invoice inside the package/s.
If you have twin turbochargers then package separately to avoid damage and place the packaging slip inside box.
Turbochargers must be in good working order and free from damage, any turbochargers sent with damage may incur extra charges*
Please do not send any accessories, oil lines, valves, hoses, parts, or components apart from the turbocharger and actuator as we will not be responsible for any losses or breakages of parts.
Pack any turbocharger individually and extremely well to avoid any transit damage, double boxing is recommended. We also recommend adding double shipping labels to the outside of your package and place one inside to ensure your package does not become lost.
