What is a hybrid turbocharger?

A hybrid turbo uses a turbocharger architecture adapted for to accommodate internal components that differ from the original d configuration. Depending on the modification, changes may involve the impellers, their geometry, the housings, the thrust bearing or the balancing.

The aim is d to adapt the compression capacity and the air flow rate d. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel: the combination of components and their aerodynamic compatibility are crucial.

MFS compressor wheel: standard or Performance?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. The wheel documented here is made from forged aluminium and is characterised by a geometry designed for high airflow. The original technical data sheet d indicates an additional compression capacity of 15 per cent.

A standard MFS impeller can retain a geometry equivalent to the original. An MFS impeller Performance can be adapted with a profile, blade height or diameter suited to the modification, provided these changes are documented.

A standard MFS impeller can be as polished as an MFS impeller Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d'air. A higher flow rate can only be utilised correctly with appropriate engine tuning.

Why does the geometry of the blades influence the air flow rate d?

The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and blade arrangement all influence its aerodynamic behaviour. The result also depends on the casings, the turbine wheel, the boost pressure and the engine management system. A larger wheel therefore does not automatically guarantee better performance and may alter the response time.

Reliability and balancing of the hybrid turbo

The 360° thrust bearing fitted to all three stages distributes axial forces across a suitable surface. It helps to stabilise the assembly without compromising lubrication or fitting requirements.

The rotor is balanced at high speed, up to 150,000 rpm on a Cimat VSR test bench, to minimise vibrations and mechanical stresses. This balancing does not protect the turbocharger against incorrect installation, contamination or a fault in the oil supply d.

Engine remapping and preparation

Adjustments to the mapping and pressure control are required for to make the most of the hybrid turbo’s characteristics. Depending on the tuning package and the vehicle, the fuel injection, exhaust, air cooling d'intake, clutch or gearbox must also be checked. The wastegate must be adjusted whilst remapping the ECU. The turbo alone does not guarantee any specific final power output.

How do you identify the correct turbo?

Check the part number marked on the original turbo d, then compare the OEM and manufacturer part numbers.. Also check the make, model, generation, engine type, power output at hp, theYear and the engine code where available.. An identical engine type is not always sufficient to confirm compatibility.

If you are unsure about the identification, please contact us with the part number clearly visible on your original turbo d.
