TTE855 EVO Upgraded Turbocharger - 8V RS3 & 8S TTRS 2.5T

A TTE855 Is an original RS3 8V.2/TTRS 8S turbocharger for the DAZA & DNWA 2.5 TFSI EVO engine that 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 the 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 aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power. Equally, the original exhaust turbine is exchanged for a far larger but very lightweight 9 blade TTE designed turbine, for lower exhaust gas backpressure, giving greater performance. A TTE motorsport upgrade bearing system is also fitted for durability.

Boost response as always is focused on when 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 the exhaust manifold has been CNC ported 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.
