A TTE777 Is an original RS3 8V.2/TTRS 8S turbocharger that we the THETURBOENGINEERS Rework to make a class-leading performance hybrid for the older generation cars. 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. You can achieve 650whp with 93 octane / 99 RON with supporting modifications.
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.
If ordering new, we use the latest generation of BorgWarner original turbochargers with the latest spec Audi thermal shielding on the exhaust manifold & turbine housing to lower engine bay temperatures and ensure the best performance and safety. Please note if you send an older generation turbo, without the original thermal shielding for the "upgrade" process, we will rework your turbo and return without the shielding.
You may also need the TTE Audi Heat Shield Isolation Add On For TTE777 Hybrid Turbocharger (8J TTRS, 8P/8V RS3 & 8V RSQ3) if you are ordering a TTE NEW OR UPGRADE YOUR TURBOCHARGER
You will need the Forge Audi Turbo Inlet Pipe with TTE777 Adapter.
This is not a plug and play turbo, you will also need the DVX Turbo Installation Kit
The Sharp-Motorsport Audi 2.5 TFSI EVO EA855 MPI Injector Set Upgrade (Inc. 8J TTRS, 8P RS3 & 8V RSQ3) is also recommended.
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 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.
