TTE440L – Upgrade Turbo – Audi A4 / A5 / A6 / Q5 / Q7 2.0 TSI EA888.3

Description

The TTE440L is the latest hybrid turbo upgrade from TheTurboEngineers, developed for the third-generation Audi 2.0 TSI/TFSI engines (EA888.3). Suitable for the Audi A4 B8.5/B9, A5 B8.5/B9, A6, Q5, and Q7, among others. This turbo delivers over 400 hp with impressive throttle response, fast spooling, and OEM-quality installation.

The original IHI turbo forms the basis, but internally everything has been revised. The standard compressor has been replaced by a larger, CNC-machined 6+6 billet compressor wheel with extended tip technology for optimal airflow and efficiency. The compressor housing is precisely machined to ensure perfect clearance between wheel and housing. On the exhaust side, a lightweight 9-blade TTE High-Flow turbine (53 mm) lowers exhaust gas temperature and reduces back pressure, resulting in higher performance and improved durability.

The whole thing is reinforced with an in-house developed 360° bearing system, specifically designed for high boost pressure and long-term use. All components are individually balanced and dynamically tested up to 250,000 rpm, with each unit supplied with an official balance report.
