The Turbo Engineers - TTE777 Hybrid EA855 Evo Turbo Charger
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.
To make a TTE777 Hybrid turbocharger 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.
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 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.
