What is a hybrid turbo?

A hybrid turbo utilises a turbocharger architecture adapted for to accommodate modified internal components. Depending on the modification, changes may relate to the compressor wheel, its dimensions, the geometry of the blades, the machining of the housings, the thrust bearing or d other documented components.

The aim is d'to adapt the compression capacity and the air flow rate d'. However, a hybrid turbo is not defined solely by the appearance of its impeller: the balance between the components, the housings and the engine settings remains crucial.

MFS compressor wheel: standard or Performance?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This term describes its manufacturing process, but does not in itself indicate an increase in air flow d.

A standard MFS impeller may retain a geometry equivalent to that of the original d. An MFS Performance impeller may, depending on the documented specification, adopt a specific diameter, profile or blade configuration in order d to adapt its aerodynamic behaviour.

A standard MFS impeller can be just as effective 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 airflow can contribute to power output only when combined 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 influence the airflow and the compressor’s operation.

An appropriate geometry can move more air d under certain conditions. The result also depends on the compressor housing, the turbine section, the boost pressure and the engine tuning. A larger impeller can alter the response time and does not, on its own, constitute an improvement suitable for all applications.

Reliability and balancing of the hybrid turbo

The three documented modifications use a 360° bearing stop, designed for better distribute the axial forces exerted on the rotating assembly.

High-speed balancing is carried out at 150,000 rpm on a Cimat VSR test bench. This process helps to minimise vibrations and mechanical stresses on the rotor, though it does not compensate for incorrect installation, insufficient lubrication or the presence of foreign objects.

Engine remapping and preparation

To make the most of the characteristics d of a hybrid turbocharger, it may be necessary to adjust the engine mapping and boost pressure management. The wastegate must be adjusted during the fitting and remapping of the ECU.

Depending on the level of tuning, the injection system, exhaust system, cooling system, fuel supply, clutch or transmission may also require inspection or adjustment. Fitting the turbocharger alone does not automatically result in a power gain.

How do you identify the correct turbo?

Check the part number marked on the original turbo d and compare it with the OEM and manufacturer part numbers in this sheet. Also check the make, model, generation, body style, power output of the 204 hp, the production period and the engine code M57 D30 (306D2).

An identical engine specification is not always sufficient to confirm compatibility, as several different set-ups may coexist depending on the vehicle version.

If in doubt, please contact us with the part number clearly visible on your original turbocharger d.
