What is a hybrid turbo ?

A hybrid turbo is based on a specially adapted turbocharger design for to receive internal changes. Depending on the course, these may cover the compressor wheel, the casings, the turbine wheel, the thrust bearing system and balancing.

The aim is d’adjust the compression capacity and flow rate’ dair. However, a hybrid turbo is not defined solely by the appearance of its impeller: the geometry of the components and how well they fit within the housings 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 does not, on its own, guarantee an increase in throughput dair. A standard MFS wheel can retain a geometry equivalent to that d’origin’.

An MFS wheel Performance can be designed with a geometry suited to the preparation objective. In the description of this product, the wheel is described as being lighter, larger and taller than the one d’original, with a compression capacity claimed to be 15 per cent higher.

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 dair. A higher flow rate can contribute to power development when combined with the correct engine tuning, although this alone does not guarantee a specific result.

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 influence its aerodynamic behaviour and the amount d’air displaced under certain conditions’.

The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine tuning. A larger wheel therefore does not automatically guarantee a better result and may affect the response time.

Reliability and balancing of the hybrid turbocharger

The 360° stop, documented for each stage, helps to distribute the axial forces acting on the rotating assembly. It does not exempt d’proper lubrication nor d’a compliant installation’.

The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This balancing is designed to minimise vibrations and mechanical stresses, but does not protect against insufficient lubrication, contamination or incorrect installation.

Engine remapping and tuning

The engine mapping and boost pressure control need to be adjusted for make the most of the turbo’s features. The wastegate must be adjusted during remapping. Depending on the level of preparation, the fuel injection, exhaust, cooling, intake, clutch or transmission must also be checked and, if necessary, adjusted.

How do you choose the right turbo ?

Check the part number marked on the turbocharger d’origin, as well as the OEM and manufacturer’s part numbers. Also check the make, model, generation, engine type and power output in hp, the assembly period and, where available, the engine code. Having the same motor does not always guarantee compatibility.

If you are in any doubt, please contact us, quoting the reference number clearly visible on your turbocharger.
