What is a hybrid turbo ?

A hybrid turbocharger is based on a turbocharger design that has been adapted to accommodate components or machining processes that differ from the standard configuration d'origin'. Depending on the course, the preparation may involve the compressor wheel, the casings, the turbine wheel, the thrust bearing and balancing.

The aim is d'adjust the compression capacity and flow rate' d'air'. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the balance between the wheels, the housings and the engine management system 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 does not, on its own, guarantee an increase in throughput d'air'. A standard MFS wheel can retain a geometry equivalent to the original.

An MFS wheel Performance may utilise a geometry suited to the purpose of the preparation, in particular with regard to the profile, height, width or arrangement of the blades. A standard MFS wheel can be just as shiny as an MFS wheel Performance. 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 enable the engine to produce more power when combined with appropriate engine tuning, although no specific power gain can be guaranteed by the turbocharger alone.

Why does the geometry of the blades affect the flow rate? d'air?' ?

The compressor wheel draws in and then compresses the air fed to the engine. Its diameter, profile, height, width and the arrangement of its blades all influence its aerodynamic behaviour. The right geometry can move more d'air under certain operating conditions'.

The result also depends on the casings, the turbine wheel, the boost pressure and the engine tuning. A larger wheel does not automatically guarantee better performance and may affect the turbocharger’s response time.

Reliability and balancing of the hybrid turbocharger

The 360° stop fitted to all three stages helps to distribute the axial forces. However, it does not protect the turbocharger against a lack of lubrication, contamination or incorrect fitting.

Each advertised product benefits from d'high-speed balancing at 150,000 rpm on a Cimat VSR test bench'. The aim of this operation is to minimise vibrations and mechanical stresses on the rotor.

Engine remapping and tuning

It may be necessary to adjust the engine mapping and boost pressure control for make the most of the hybrid turbo’s features. The fuel injection, exhaust, cooling system, clutch and gearbox must also be checked, depending on the level of preparation. The wastegate must be adjusted when the ECU is remapped. A turbocharger on its own does not guarantee a power increase.

How do you choose the right turbo ?

Check the part number engraved or marked on the turbocharger d'original', then compare it with the OEM and manufacturer part numbers listed on this sheet. Also check the make, model, generation, engine type and power output in hp, theYear the mounting code and the engine code, where available. Having the same motor does not always guarantee compatibility.

If you are in any doubt, please contact us with the full part number of your turbocharger d'origin'.
