TTE650 4646 AUDI RS6 C5 UPGRADE TURBOCHARGERS

The TTE650 turbochargers represent our highest upgrade stage for the 4.2 TT V8 platform, delivering substantial performance gains while maintaining near-OEM response characteristics. They are especially popular among owners seeking true plug-and-play RS6-fitment units that provide broader power delivery without sacrificing factory-level drivability.

Engineered & Enhanced

Each TTE650 turbocharger begins as a genuine RS6 K04 OE unit and is meticulously re-engineered with larger, high-efficiency billet compressor wheels paired with precision-clipped turbines. All enhancements are developed using only authentic BorgWarner components to ensure uncompromised reliability and quality.

Performance with Durability

Compressor covers are CNC-machined in-house to achieve optimal tolerances, enabling seamless fitment while preserving the efficiency benefits of the advanced 2283 extended-tip billet compressor wheel design. This low-inertia wheel improves airflow and performs like a larger assembly, delivering:

  • Faster spool-up at lower RPM

  • Reduced charge temperatures

  • Stronger top-end performance

The factory turbine and shaft assembly are replaced with TTE’s proprietary 9-blade units, increasing exhaust gas flow, reducing back pressure, and lowering exhaust gas temperatures for improved efficiency and durability.

To withstand higher loads without compromising transient response, we install high-performance 360° motorsport-grade journal bearings. Uprated sprung OE actuators with reinforced clamps are also fitted to ensure consistent, trouble-free operation.

Precision Balancing — The TTE Standard

Balancing is a critical element of every TTE turbocharger. Each unit undergoes a multi-stage process:

  1. Component Pre-Balancing — Individual parts balanced at speeds up to 2,800 RPM across multiple planes.

  2. Assembly & Dynamic Balancing — Fully assembled CHRAs balanced at application-specific speeds up to 250,000 RPM using our in-house VSR system.

This rigorous process achieves equilibrium standards significantly exceeding OEM tolerances, enhancing longevity, performance, and acoustic refinement. Every turbocharger is supplied with a serial-numbered balance test certificate verifying its precision.
