What is a hybrid turbocharger?

A hybrid turbo utilises a turbocharger architecture adapted for accommodate internal components that differ from the original dconfiguration. Depending on the upgrade stage, modifications may involve the impellers, their dimensions, the housings, the thrust bearing and the balancing.

The aim is dto adapt the compression capacity and air flow rate d. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel, but by the consistency of its geometry and mechanical modifications.

MFS compressor wheel: standard or Performance?

MFS stands for ‘Milled From Solid’: the impeller is machined from a solid block. This technology describes its manufacturing process and does not, on its own, guarantee an increase in air flow d.

A standard MFS impeller may retain a geometry equivalent to the original. An MFS Performance impeller can be fitted with a profile, blades or diameter tailored to the intended modification. On this product, the impeller shown is made of forged aluminium, lighter, larger and taller than the original d; it is rated for, allowing for 15 per cent additional compression.

A standard MFS impeller can be just 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 airflow can help to develop more power with a consistent engine set-up, though this alone does not guarantee a specific result.

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 housings, the turbine wheel, the boost pressure and the engine tuning. A larger wheel does not automatically guarantee better performance and may alter the response time.

Reliability and balancing of the hybrid turbo

The 360° thrust bearing distributes axial forces across a surface area suited to the rotor’s stresses. Each stage presented includes this thrust bearing as well as high-speed balancing at 150,000 rpm on a Cimat VSR test bench, designed to minimise vibrations and mechanical stresses. However, this balancing does not compensate for faults in assembly or lubrication.

Engine remapping and preparation

Appropriate engine management is required for to make full use of the hybrid turbo’s characteristics. The mapping, boost pressure, injection, exhaust and cooling must be checked or adjusted according to the vehicle. The wastegate must be adjusted when remapping the ECU. The clutch, transmission and other components may also require inspection depending on the configuration.

How do you identify the correct turbo?

Check the turbo’s part number d, the original OEM and manufacturer part numbers, as well as the make, model, generation, engine type, power output,Year and engine code.. An identical engine type is not always sufficient to confirm compatibility.

If in doubt, please contact us with the part number from your turbocharger.
