TTE550 5654 AMG M133 A45 / CLA / GLA UPGRADE TURBOCHARGER
The TTE550 Stage 3 Hybrid Turbocharger by TheTurboEngineers is engineered specifically for the 2.0L AMG M133 four-cylinder engine found in the Mercedes-AMG A45, CLA45, and GLA45 models. Designed as a high-performance upgrade, the TTE550 delivers substantial power gains while maintaining reliability, drivability, and fast response characteristics.
Advanced Compressor & Turbine Engineering
To create the TTE550, the original compressor assembly is replaced with a significantly larger and more efficient billet compressor wheel featuring extended tip technology. The compressor cover is precision CNC-machined to achieve optimal clearance, ensuring maximum efficiency and airflow performance tailored to the upgraded wheel profile.
On the turbine side, the factory turbine is replaced with a specially developed TTE lightweight 9-blade turbine. The turbine housing is CNC-machined to accommodate the enlarged turbine geometry, allowing substantially increased exhaust gas flow.
The proprietary 9-blade turbine design offers several key advantages:
Increased gas flow capacity
Reduced exhaust back pressure
Lower exhaust gas temperatures (EGTs)
Enhanced durability at higher boost pressures
Thanks to its low mass and reduced moment of inertia, the turbine provides rapid spool characteristics despite its increased size—delivering strong top-end power without compromising responsiveness.
Upgraded Bearing System
The original bearing assembly is replaced with a TTE performance bearing pack, incorporating a 360-degree thrust bearing system. This upgrade enhances load capacity, durability, and stability under high boost and high-RPM operating conditions.
Precision Balancing – Ultimate Equilibrium
Precision balancing is a critical factor in every TTE turbocharger, directly influencing longevity, efficiency, acoustics, and overall performance.
Each TTE550 undergoes a rigorous multi-stage balancing process:
Component Pre-Balancing – Individual rotating components are balanced at low speeds (up to 2,800 RPM) across multiple planes using specialized single-part balancing equipment.
CHRA Dynamic Balancing – Once assembled, the complete CHRA (Center Housing Rotating Assembly) is dynamically balanced at speeds of up to 250,000 RPM using TTE’s in-house VSR (Vibration Sorting Rig) machine.
This comprehensive process achieves balance tolerances significantly exceeding OEM standards, ensuring smooth operation at extreme rotational speeds.
Every turbocharger is supplied with a serial-numbered balance test certificate, verifying the precise equilibrium achieved during production.
