What is a hybrid turbo?

A hybrid turbo retains a turbocharger architecture designed for to accommodate modified internal components. Depending on the upgrade stage, the modifications may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing or balancing.

The aim is d to adapt the compression capacity and air flow d to the requirements of the tuning. A hybrid turbo is not defined solely by the appearance of its impeller: the geometry, the machining of the housings and the overall balance of the unit are decisive.

MFS compressor wheel: standard or ‘ Performance ’?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone is not sufficient to achieve an increase in air flow d.

A standard MFS impeller may retain a geometry equivalent to that of the ori d. An MFS Performance impeller may be given a geometry adapted to the tuning, particularly in terms of its profile or dimensions, provided these modifications are documented.

A standard MFS wheel can be just as shiny as an MFS wheel Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more d'air. The data provided for for this product describe a forged aluminium impeller, which is lighter, larger and taller than the d'original, allowing for 15 per cent additional compression.

Why does the geometry of the blades influence the air flow 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 its ability to move air.

The result also depends on the casings, the turbine wheel, the boost pressure and the engine set-up. A larger wheel can alter the response time and the optimal operating conditions d; its size alone is therefore not sufficient to determine the turbo’s behaviour.

Reliability and balancing of the hybrid turbo

The documented 360° bearing thrust ring helps to distribute axial forces around the shaft. It must operate with correct lubrication and be fitted correctly.

The rotor is balanced at high speed, at 150,000 rpm on a Cimat VSR test bench, in order to minimise vibrations and mechanical stresses. This balancing does not compensate for inadequate lubrication, contamination or incorrect fitting.

Engine remapping and preparation

Appropriate engine management is required for to make the most of the hybrid turbo’s characteristics. Fuel injection, exhaust, cooling and the engine control unit must be checked or adjusted according to the project. The wastegate must be adjusted during the reprogramming of the engine control unit. The clutch, the gearbox and other vehicle components must also be checked depending on the level of preparation.

How do you identify the correct turbo?

Check the turbo part number d the original, OEM and manufacturer part numbers, as well as the make, model, engine type, power output, installation period and engine code. An identical engine type may have several different configurations.

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