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 this TTE777 stage we have CNC ported the exhaust manifold as standard at the head flange to smooth the transition from head to exhaust runner for maximum gas speed and so improving efficiency to the much bigger 9 blade low mass turbine and so driving the larger compressor harder and we also made other power modifications with regards to the turbine side of the TTE777 unit.  

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.

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 serial numbered balance test result document.

Upgrade your Existing Turbo

To upgrade your existing turbo, you will need to send us your non-damaged turbo. The listing price is the cost of upgrading a non-damaged turbo only. If your turbo is damaged, there may be extra cost on top of the listing price, we will provide you with a quote after inspection. All turbo will be closely inspected before the upgrade is carried out. You will also receive a report from our engineer after the upgrade is completed.

• Audi TTRS 8S 2.5 TFSI
• Audi RS3 8V.5 2.5 TFSI

To ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch. We can do this either using your registration number(UK) or the last 7 digits of your VIN. Simply enter your car details prior to checkout.
