What is a hybrid turbo?

A hybrid turbo retains a turbocharger design suitable for for internal modifications. Depending on the modification, these may involve the compressor wheel, its geometry, its dimensions, the housings, the turbine wheel, the thrust bearing system or the balancing.

The aim is d to adapt the compression capacity and air flow d to the engine’s requirements. A hybrid turbo is therefore not defined solely by the appearance of its compressor wheel, but by the coherence of all its components and settings.

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 guarantee an increase in air flow d.

A standard MFS impeller may retain a geometry equivalent to that of the original d. A Performance MFS impeller can be given a geometry tailored to the tuning objective, in particular a specific diameter, profile or blade configuration, provided these elements are documented.

A standard MFS impeller can be just as shiny 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 the development of more power with suitable engine tuning, though this alone does not guarantee results.

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 the arrangement of its blades influence its aerodynamic behaviour and the amount d of air it can move under certain conditions.

The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine set-up. An increase in dimensions can alter the response time as well as the optimum operating range.

Reliability and balancing of the hybrid turbocharger

The 360° thrust bearing, documented in both training courses, helps to distribute the axial forces exerted on the rotating assembly. It must operate with adequate lubrication and does not protect the turbocharger against incorrect installation.

The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses, but does not compensate for inadequate lubrication, contamination or assembly errors.

Engine remapping and preparation

Adjustments to the engine management system may be necessary for to make the most of the hybrid turbo’s characteristics. The mapping, boost pressure, fuel supply, intake air cooling d, the exhaust and the transmission must be checked in accordance with the level of tuning.

The wastegate must be adjusted during installation and when remapping the ECU. Without a coherent tuning programme, the installation d of a hybrid turbo does not automatically guarantee a power gain.

Fitting advice

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 data sheet.. Also check the make, model, generation, engine type, power output at hp, theYear and the engine code where available.

The same engine type may be fitted with different turbo set-ups depending on the version or production period.

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