TTE840 5154 C7 4.0 TFSI Upgrade Turbochargers
Compatible with select 4.0 TFSI models from Audi (RS6, RS7, S8, S7, S6 C7 platforms) and Bentley Continental GT V8 / V8S variants.
Performance Overview
The TTE840 5154 represents the first hybrid performance upgrade stage for the 4.0 TFSI platform, delivering a substantial increase in power output while maintaining fast spool characteristics and responsive drivability. Designed for enthusiasts seeking enhanced performance without sacrificing reliability, this upgrade balances efficiency, durability, and precision engineering.
Engineered & Enhanced Construction
Each pair of TTE840 turbochargers undergoes extensive modification and optimization of the original units:
Replacement of the factory compressor with a significantly larger, high-efficiency billet compressor wheel featuring extended-tip technology
Precision machining of the compressor cover to achieve optimal clearance and aerodynamic efficiency
Installation of an enlarged TTE 9-blade turbine wheel to improve exhaust gas flow and overall performance
Integration of TTE’s upgraded bearing system to support long-term durability under high-performance conditions
Precision Balancing & Quality Assurance
Accurate balancing is essential for turbocharger longevity, refinement, and performance. Every TTE unit is subjected to a meticulous multi-stage balancing process:
Component Pre-Balancing: Individual parts are balanced at low speeds up to 2,800 RPM across multiple planes using specialized single-component machinery.
Assembly Balancing: After assembly, the CHRA is dynamically balanced at application-specific speeds of up to 250,000 RPM using TTE’s in-house VSR system.
Certification: Each turbocharger set is supplied with a serial-numbered balance test report verifying compliance with standards exceeding OEM specifications.
