What is a hybrid turbo ?

A hybrid turbo is based on a specially adapted turbocharger design for to receive internal components that differ from the configuration d’origin’. Depending on the service, modifications may relate to the compressor wheel, its dimensions, the geometry of the blades, the housing, the thrust bearing or the balancing.

The aim is d’adjust the compression capacity and flow rate’ dair. However, a hybrid turbo is not defined solely by the appearance of its impeller: its dimensions, geometry and the adaptation of the associated components are crucial.

MFS compressor wheel: standard or Performance ? ?

MFS stands for ‘Milled From Solid’: the wheel is machined from a solid block. This manufacturing process does not, on its own, guarantee an increase in throughput dair. A standard MFS wheel can retain a geometry equivalent to that d’origin’.

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 dair. An MFS wheel Performance can be fitted with blades of a specific diameter, profile or configuration. A higher flow rate can help to generate more power with the right engine tuning, although this alone does not guarantee a gain.

Why does the geometry of the blades affect the flow rate? d’air ?

The compressor wheel draws in and then compresses the air admitted by the engine. Its diameter, profile, height, width and the arrangement of its blades all influence its aerodynamic behaviour. The result also depends on the compressor housing, the turbine, the boost pressure and the engine tuning. A larger wheel therefore does not automatically guarantee better performance and may affect response time.

Reliability and balancing of the hybrid turbocharger

The 360° stop, as documented for each stage, distributes the axial forces around the bearing. The rotor is balanced at high speed – up to 150,000 rpm – on a Cimat VSR test bench in order to minimise vibrations and mechanical stresses. This balancing does not protect against insufficient lubrication, contamination or incorrect installation.

Engine remapping and tuning

The engine management system needs to be adjusted for make the most of the preparation’s characteristics. Mapping, boost pressure, fuel injection, exhaust and cooling must be checked or adjusted to suit the specific set-up. The wastegate must be adjusted during fitting and remapping. The clutch, gearbox and other components subject to stress must also be checked, depending on the vehicle.

How do you choose the right turbo ?

Check the part number marked on the turbocharger dthe original, then compare the OEM and manufacturer part numbers. Also check the make, model, generation, body style, engine type and power output of 90 hp, the assembly period and the engine code. A single motor can be fitted with several different configurations.
