What is a hybrid turbo ?

A hybrid turbo utilises a turbocharger design adapted to accommodate internal components that differ from the standard configuration d’origin’. Modifications may relate to the compressor wheel, the turbine, the casings, the thrust bearing system and the balancing process.

The aim is d’adjust the compression capacity and flow rate’ dair to meet the requirements of the preparation. A hybrid turbocharger is therefore not defined solely by the appearance of its impeller, but by the consistency of its geometry and the associated mechanical modifications.

MFS compressor wheel: standard or Performance ? ?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process does not, in itself, mean that the wheel has a higher-flow geometry. A standard MFS wheel can retain dimensions and a profile similar to the original.

An MFS wheel Performance can be fitted with a design tailored to the application: taller or wider blades, a different profile, a modified diameter or a specific configuration. For this product, the wheel is described as being made of forged aluminium, and is lighter, larger and taller than the one d’original, with a claimed compression capacity 15 per cent higher.

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. Higher power output can only be fully utilised with appropriate engine tuning.

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

The compressor wheel draws in and then compresses the air fed to the engine. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour and the amount d’the volume of air it can move depending on the operating mode’.

The result also depends on the casings, the turbine wheel, the boost pressure and the engine management system. A larger wheel is not necessarily better: its size can affect the response time and the range doptimal use.

Reliability and balancing of the hybrid turbocharger

The 360° stop fitted to all three stages distributes the axial forces over a wide area. It helps to ensure the mechanical stability of the bearing within the frame d’use and d’suitable lubrication’.

The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This procedure is designed to minimise vibrations and mechanical stresses, without compensating for incorrect assembly, contamination or an insufficient oil supply.

Engine remapping and tuning

The maps need to be updated for make the most of the hybrid turbo’s features. Boost pressure, fuel injection, exhaust, cooling and, depending on the configuration, the transmission must be checked or adjusted. The wastegate must be adjusted when the engine control unit is remapped.
