TTE777 EVO Turbocharger for the DAZA & DNWA 2.5 TFSI EVO engine

A TTE777 Is an original RS3 8V.2/TTRS 8S turbocharger that we the THETURBOENGINEERS Rework to make a class-leading performance hybrid yet still plug & play fitting with an upgrade inlet. To make a TTE777 the compressor wheel is exchanged for a TTE milled aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power, that's even bigger then TTE700 wheel. Equally, we change the original exhaust turbine for a far larger but very lightweight 9 blade TTE designed the turbine for lower exhaust gas backpressure giving greater performance. We also fitted a 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.

I know most people perform turbo tuning with bolt-on modifications like intake, turbo, intercooler & exhaust etc for good reason.

But does anyone use traditional, internal methods like big valves, ported heads etc? How do they get on?

Thanks, Nick
