A TTE777 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 TTE777 Hybrid turbocharger was the evolution of our highly acclaimed TTE700.  Using some key features like a bigger billet compressor and CNC porting and other gas flow improvements. 

The compressor wheel is exchanged for a milled aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power that is even bigger then the TTE700 compressor wheel. 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 the TTE777 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 TTE777 unit to increase gas flow.  

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.
