What is a hybrid turbo?

A hybrid turbo uses a turbocharger architecture adapted for accommodate modified internal components. Depending on the upgrade stage, the modification may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing and balancing.

The aim is d to adapt the compression capacity and air flow rate d. A hybrid turbo is not defined solely by the appearance of its impeller: its geometry, the machining of the housings and the consistency between the components are also crucial.

MFS compressor wheel: standard or Performance?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This technology describes the manufacturing process and does not, on its own, guarantee an increase in air flow rate d. A standard MFS wheel can retain a geometry equivalent to that d of the original.

An MFS wheel Performance can be adapted to suit the. On this product, the wheel shown is made of forged aluminium; it is lighter, larger and taller than the d original; it is designed for to allow for 15 per cent additional compression. Oversized versions require the intake housing to be re-profiled d.

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 flow rate can only be fully utilised with appropriate engine tuning.

Why does the geometry of the blades influence the air flow rate d?

The compressor impeller draws in and then compresses the air admitted by 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 compressor housing, the impeller and the turbine housing, the boost pressure and the engine management system. A larger impeller therefore does not automatically guarantee better performance and may alter the response time as well as the optimal operating range d.

Reliability and balancing of the hybrid turbo

The 360° bearing stop helps to distribute the axial forces exerted on the rotating assembly. It is a component suited to the stresses of this modification, without making the turbocharger immune to installation or lubrication faults.

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 on the rotating assembly.

Engine remapping and tuning

Appropriate engine management is required for to make the most of the characteristics d of a hybrid turbo. The mapping, boost pressure, fuel injection, exhaust and cooling systems must be checked or adjusted according to the level of tuning.

The wastegate must be adjusted when remapping the ECU. The clutch, gearbox and other components under stress must also be checked depending on the vehicle and the desired outcome. The turbo alone does not 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 datasheet. Also check the make, model, body style, engine type 2.5 CRDi, the power output at hp, the production period and the engine code where available. An identical engine specification does not always guarantee compatibility.
