What is a hybrid turbo?

A hybrid turbo retains an architecture suited to the intended installation whilst incorporating internal modifications. Depending on the modification package, these may involve the compressor impeller, the housings, the turbine impeller, the thrust bearing system and the balancing.

The aim is d to adapt the compression capacity and air flow d to the requirements d of an engine upgrade. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the wheels, their combination with the housings and the quality of the balancing are crucial.

MFS compressor wheel: standard or ‘ Performance ’?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. The wheel documented here is made from forged aluminium and features a design that is lighter, larger and taller than the d original. The available data indicates an additional 15 per cent boost capacity.

A standard MFS wheel can retain a geometry equivalent to the original. Conversely, an MFS wheel Performance can be given a geometry tailored to the tuning objective, such as a different blade profile, height, width or diameter, where these elements are specified.

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 rate can contribute to power output with appropriate engine tuning, though it does not, on its own, guarantee a specific result.

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, the blade profile, their height, width and arrangement all influence the compressor’s aerodynamic behaviour.

A suitably designed geometry can move more air d within certain operating ranges. The result also depends on the casings, the turbine wheel, the boost pressure and the engine tuning. A larger wheel therefore does not automatically guarantee a better result and may alter the response time.

Reliability and balancing of the hybrid turbo

The 360° bearing stop, featured on all three stages, distributes axial forces over a wide surface area. It contributes to the mechanical integrity of the assembly without making the turbo 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 during rotation.

Engine remapping and preparation

To make the most of the characteristics d of a hybrid turbo, the engine management system must be adapted. The mapping, boost pressure and wastegate settings must be checked when remapping the ECU.

Depending on the level of tuning, the injection d, exhaust d and cooling systems may also require checking or adjustment. The clutch, gearbox and other vehicle components must remain compatible with the chosen configuration.

Installation advice

How do you identify the correct turbo?

Check the part number engraved or marked 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, body style, engine type, power output at hp, production period and engine code where available.

An identical engine specification does not always guarantee compatibility, as there may be several different set-ups for for the same version.
