What is a hybrid turbocharger?

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

The aim is d to adapt the compression capacity and d air flow. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: consistency between the wheels, housings and engine management remains 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'air. A standard MFS wheel may retain a geometry equivalent to that d'of the original.

An MFS wheel Performance is characterised by a geometry tailored to the tuning objective. On this product, the wheel shown is made of forged aluminium, lighter, larger and taller than the d original; the technical data sheet indicates an additional compression capacity of 15 per cent.

A standard MFS impeller can be just as effective 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 only be utilised properly with a suitably tuned engine.

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.

. The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the turbo mapping. A larger impeller therefore does not automatically guarantee better performance and may alter the turbo’s response time.

Reliability and balancing of the hybrid turbo

The 360° bearing thrust ring, present on all three stages, helps to distribute the axial forces exerted on the rotating assembly. It does not, however, d'replace the need for proper lubrication or d'correct installation.

High-speed balancing at 150,000 rpm on a Cimat VSR test bench is designed to minimise vibrations and mechanical stresses on the rotor. It does not protect the turbocharger against incorrect installation, a fault d in the oil supply or the presence d of a foreign object.

Engine remapping and tuning

The engine ECU and boost pressure management must be adjusted for to make the most of the tuning’s characteristics. The wastegate must be adjusted during remapping. Depending on the configuration, the fuel injection, exhaust system, air d intake cooling, clutch or gearbox may also need to be checked or adjusted. Fitting d a hybrid turbo does not automatically guarantee a power gain.

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 sheet. Also check the make, model, generation, body style, engine type, power output ( hp), production period and engine code. An identical engine type is not always sufficient to confirm compatibility.

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