TTH Turbocharger Upgrade (Racing)
McLaren – M840T
High-end turbocharger optimization for the McLaren M840T 4.0 V8 BiTurbo – maximum efficiency, reduced exhaust back pressure and the technical basis for extreme performance levels up to four figures.
Description
The TTH turbocharger upgrade for the McLaren M840T 4.0-liter V8 twin-turbo is a consistently performance-oriented optimization of the OEM turbochargers. The focus is on significantly improved flow efficiency on both the compressor and turbine sides to create a stable and robust foundation for extreme power increases , even at high airflow rates. The result: more reserves, greater pressure stability, and a setup designed for uncompromising high-power applications.
Technology & Construction
- Milled extended-tip compressor wheel with modern compressor geometry
- Gap optimization through CNC-machined compressor and exhaust housing
- 9-Blade Performance exhaust turbine for reduced exhaust back pressure
- Precision balancing for smooth running and continuous load stability
- Plug-and-play installation (vehicle-specific)
- Optimization / In-house manufacturing (TTH)
Application area & performance
- Technical basis for performance increases up to the 1200 hp range (vehicle & setup dependent)
- More air mass with high efficiency – ideal for consistent high-power setups
- Improved pressure and temperature stability under high continuous load
- Perfect foundation in combination with suitable engine components & ECU adaptation
Requirements
- For variants based on the machining of supplied turbochargers , the following applies: Turbochargers must be technically sound (no oil problems, no boost pressure problems, no grinding/whistling, etc.).
- To unlock its full potential , appropriate engine components and a customized engine control unit tuning are required.
compatibility
- McLaren 720S - M840T 4.0 V8 BiTurbo
- McLaren 765LT – M840T 4.0 V8 BiTurbo
Suitable exclusively for vehicles with M840T 4.0 V8 BiTurbo engine.
