TTE855 TURBOCHARGER - DAZA / DNWA / DNWC (New unit supplied)

TTE855 EVO 2.5TFSI UPGRADE HYBRID TURBOCHARGER FOR RS3 8V.2 & 8Y / TTRS 8S DAZA, DNWA, DNWC

The TTE885 Is the best performing hybrid available with lightning-fast spool considering has been proven at 900PS! 

A TTE855 Is an original RS3 8V.2/TTRS 8S turbocharger for the DAZA & DNWA 2.5 TFSI EVO engine that we the THETURBOENGINEERS Rework to make a class-leading performance hybrid, yet still being plug & play fitting with an upgrade inlet.  

The TTE855 Hybrid turbocharger was the evolution of our highly acclaimed TTE777.  Using some key features like the bigger billet compressor and CNC porting and other gas flow improvements and of course the highly proven TTE uprated bearing system. 

The compressor wheel is exchanged for a milled aluminium wheel with state-of-the-art geometry, 7+7 blade so producing extra power. Equally, we change the original exhaust turbine for a far larger but very lightweight 9 blade TTE designed turbine, for lower exhaust gas backpressure, giving greater performance. We also fitted a proven TTE motorsport upgrade bearing system for durability.

Boost response as always is focused on when we were designing this unit and it does not disappoint with test results showing 500Nm at only 2620 RPM and 900Nm at 3500RPM!

With the TTE855 stage we have CNC ported the exhaust manifold to match the OEM gasket at the head flange and smooth the transition in each exhaust runner to improve gas speed and flow, so improving efficiency to the much bigger 9 blade low mass turbine and so driving the larger compressor harder. We also made other power modifications with regards to the turbine side of the TTE855 unit to increase gas flow.  

If ordering new, we use the latest generation of BorgWarner original turbochargers with the latest spec Audi thermal heat isolation shielding on the exhaust manifold & turbine housing to lower engine bay temperatures and ensure the best performance and safety.

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.
