What makes the TTE600 special

• Milled billet compressor wheel with new‑generation thin‑blade geometry for exceptional efficiency and flow
• Enlarged, ported and re‑profiled compressor covers for smooth, unrestricted intake paths and optimised clearances
• High‑flow 9 vane turbine and CNC‑machined turbine housing profile to reduce back pressure and lower EGT
• Carefully controlled turbine clipping to improve gas flow and response while managing thermal load
• Re‑engineered wastegate arm, flapper and bushing to combat rattle and deliver consistent boost regulation
• TTE 2 inch billet inlets included for increased mass airflow potential
• OE stock location fitment — no fabrication, no relocation, twin intake feeds retained
• Designed, machined and assembled in Germany for the N54 platform

Precision balance and reliability

Each unit is dynamically balanced far beyond factory standards. Individual components are balanced up to 2,800 rpm, then the complete CHRA is VSR balanced in‑house up to 250,000 rpm across multiple planes. Every turbo ships with a serial‑numbered balance test report for confidence and traceability.

Real‑world results on pump fuel

• 647.9 hp and 862.4 Nm on 100 RON, no meth, no ethanol
• 676.1 bhp and 970.2 Nm on 102 RON, no meth, no ethanol

For longevity and thermal efficiency, we recommend targeting around 600 PS on standard pump fuel for regular use.

Why enthusiasts pick TTE600 for the N54

• Stock‑frame simplicity with big‑power headroom
• Rapid spool and strong torque for road use with clean top‑end pull for track
• Lower exhaust manifold pressure for safer boost and repeatable performance
• Excellent drivability and refinement thanks to reinforced wastegate hardware
