What is a hybrid turbo?

A hybrid turbo is based on a turbocharger architecture adapted for to accommodate modified internal components. Depending on the modification, these changes may involve the compressor wheel, its dimensions and the geometry of its blades, the housings, the turbine wheel, the thrust bearing or the balancing.

The aim is d to adapt the compression capacity and the air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its impeller: the dimensions, geometry, machining and overall consistency of the assembly are crucial.

MFS compressor wheel: standard or ‘ Performance ’?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone does not 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 impeller Performance can be given a geometry specific to the tuning objective: different diameter, adapted profile or specific blade configuration. For this product, the dimensions and the 11+0 configuration are detailed separately for for each stage.

A standard MFS impeller can be just as effective as a custom- Performance MFS impeller. 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 contribute to the generation of more power when the engine is suitably tuned.

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

The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and blade arrangement influence its aerodynamic behaviour and the amount d of air it can move depending on operating conditions.

The result also depends on the compressor housing, the turbine section, the boost pressure and the engine management system. A larger impeller therefore does not automatically guarantee better performance in all conditions and may affect response time.

Reliability and balancing of the hybrid turbo

The 360° bearing stop documented for across all three stages helps to distribute the axial forces to which the rotor is subjected. Its effectiveness depends on correct lubrication and adherence to fitting specifications.

Each modification undergoes d high-speed balancing at 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses on the rotor; it does not compensate for incorrect installation, contamination or inadequate lubrication.

Engine remapping and preparation

Operating d a hybrid turbo may require adjustments to the engine mapping and boost pressure management. Fuel injection, the exhaust system, intake air cooling d, the clutch and the transmission must also be checked and adjusted according to the vehicle and the level of tuning.

The wastegate must be adjusted during installation and when reprogramming the ECU. A hybrid turbo does not automatically deliver a power gain without a coherent engine configuration.

Assembly tips

How do you identify the correct turbo?

Check the part number on the original turbo d, then compare it with the OEM and manufacturer part numbers in this data sheet.. Also check the make, model, generation, engine variant (2.2 D), power output (150 hp ) and production period (. ). An identical engine variant is not always sufficient to confirm compatibility.

If in doubt, please contact us with the part number clearly visible on your turbocharger.
