TTH EA839 700 Turbocharger Upgrade
Audi RS4 B9 & RS5 F5 – 2.9 TFSI Bi-Turbo
Maximum turbocharger upgrade for the EA839 – consistently designed for high performance with enormous air flow, extreme pressure stability and maximum power reserves.
Description
The TTH EA839 700 turbocharger upgrade represents the most powerful upgrade for the 2.9 TFSI twin-turbo engine (EA839) . This setup was developed for uncompromising performance projects where maximum power, thermal stability, and pressure resistance are paramount. Thanks to extensively optimized compressor and turbine sides, the reworked OEM twin-turbochargers provide the necessary air mass for power outputs of up to approximately 700 hp – while maintaining controllable responsiveness and high durability.
Technology & Construction
- Large-dimensioned high-flow extended-tip compressor wheels
- Intensive CNC-machined compressor housings for maximum flow
- Significantly redesigned turbine side to reduce exhaust back pressure
- High-precision fine balancing for extreme speeds
- OEM base housing with perfect plug-and-play fit
- Racing-oriented design for high continuous load
- Development and manufacturing in Germany
Application area & performance
- Designed for high-performance setups up to approximately 700 hp
- Very high pressure stability even at greatly increased boost pressure.
- Enormous performance reserves for consistent modifications
- Stable performance under extreme thermal stress
- Ideal for track and racing-oriented vehicles
Conversion note
- Machining of the delivered series turbochargers
- Turbochargers must be technically sound and undamaged.
- Prior inspection is necessary in case of wear or defects.
compatibility
- Audi RS4 B9 – 2.9 TFSI Bi-Turbo (EA839)
- Audi RS5 F5 – 2.9 TFSI Bi-Turbo (EA839)
The achievable performance depends on the overall vehicle, additional hardware used, fuel quality, and individual tuning.
Notes
This turbocharger upgrade requires extensive additional hardware and individual engine control unit (ECU) remapping . Installation and commissioning must be carried out exclusively by a qualified workshop . Changes to performance and emissions may restrict use on public roads.
