Available set-ups — Stage 1, Stage 2 and Stage 3

What is a hybrid turbo?

A hybrid turbo is based on a turbocharger architecture adapted for accommodate internal components that differ from the d original configuration. Depending on the upgrade stage, modifications may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system and the balancing.

The aim is d to adapt the compression capacity and the d air flow. However, a hybrid turbo is not defined solely by the appearance of its wheel: the geometry of the components and how they are combined are decisive.

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, but does not in itself guarantee an increase in air flow rate d.

A standard MFS impeller may retain a geometry equivalent to that of the original d. An MFS Performance impeller can be given a geometry tailored to the tuning objective. On this product, the impeller shown is made from forged aluminium, and is lighter, larger and taller than the original d.

A standard MFS impeller can be just as polished 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 help to generate more power when the engine is suitably tuned, though this alone does not guarantee a specific gain.

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

The compressor impeller draws in and then compresses the intake air. Its diameter, profile, height, width and the arrangement of its blades influence its aerodynamic behaviour and the volume d of air displaced within certain operating ranges.

The result also depends on the casings, the turbine wheel, the boost pressure and the engine management system. An increase in size can alter the response time as well as the optimal operating conditions d for the turbo.

Reliability and balancing of the hybrid turbocharger

The documented 360° thrust bearing distributes axial forces over a wide surface area. The rotor is balanced at high speeds, up to 150,000 rpm on a Cimat VSR test bench, to minimise vibrations and mechanical stresses.

These features do not compensate for inadequate lubrication, contamination of the system or incorrect installation.

Engine remapping and preparation

Operating d a hybrid turbo requires engine management tailored to its configuration. The mapping, boost pressure, fuel injection, exhaust and cooling must be monitored or adjusted according to the level of tuning.

The wastegate must be adjusted when remapping the ECU. The clutch, gearbox and other vehicle components may also require checking. A hybrid turbo does not automatically guarantee a power gain without appropriate tuning.

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, body style, engine type, power output at hp, production period and engine code where available.

An identical engine specification is not always sufficient to confirm compatibility, as several different set-ups may co-exist.
