What is a hybrid turbo?

A hybrid turbo is based on a turbocharger design that has been adapted to accommodate internal components or machining that differ from the standard configuration. Depending on the modification, changes may relate to the compressor wheel, its dimensions, the geometry of the blades, the housings, the thrust bearing or the balancing.

The aim is dto adapt the compression capacity and air flow rate dto the requirements of the tuning. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: consistency between the wheel, the housings and the engine settings remains essential.

MFS compressor wheel: standard or ‘ Performance ’?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This designation describes its manufacturing process, but does not in itself guarantee an increase in air flow d.

A standard MFS impeller may retain a geometry equivalent to that of the ori d. An MFS Performance impeller may, depending on its design, feature a blade profile, dimensions or configuration tailored to the intended modification.

A standard MFS impeller can be just as glossy as a custom- Performance d MFS impeller. It is not its appearance that determines its performance, but its geometry and its ability to move more dair. A higher airflow can contribute to an increase in power when the engine management system and associated equipment are correctly adapted.

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 the arrangement of its blades influence its aerodynamic behaviour and its ability to move air depending on operating conditions.

The result also depends on the compressor housing, the turbine section, the boost pressure and the engine calibration. A larger impeller therefore does not automatically guarantee a better result in all situations and may alter the turbo’s response time.

Reliability and balancing of the hybrid turbo

The 360° bearing stop present on all three stages helps to distribute axial forces over a wider surface area. It helps the turbo adapt to the stresses of tuning without making it immune to faults drelating to oil, assembly or adjustment.

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

Engine remapping and preparation

To make the most of the characteristics dof a hybrid turbo, it may be necessary to adjust the engine mapping, boost pressure and wastegate settings. The fuel supply, the exhaust, the intake air cooling das well as the transmission must also be checked depending on the level of tuning.

Fitting da hybrid turbo does not automatically guarantee a power gain. Adjustments must be carried out by a competent professional, taking into account the vehicle’s overall configuration.

How do you identify the correct turbo?

Check the part number marked on the original turbo dand compare it with the OEM part numbers in this data sheet. Also check the make, model, generation, engine type, power output at hp, installation period and engine code. An identical engine may be fitted with several different turbo configurations.

If in doubt, please contact us with the full part number of your original turbo dand your vehicle details.
