Understanding hybrid tuning

What is a hybrid turbo?

A hybrid turbo retains a turbocharger architecture suitable for accommodate internal modifications. Depending on the upgrade package, these may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing system or even balancing.

The aim is dadapt the compression capacity and air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the components and how they interact determine its performance.

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. A standard MFS wheel may retain a geometry equivalent to that dof the original.

An MFS wheel Performance can be given a geometry adapted to the modification, in particular through its profile, height, width or diameter, where such modifications are planned. For this product, the MFS wheel is documented as being lighter, larger and taller than the original d, with a claimed 15 per cent higher compression capacity.

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 contribute to power output when the engine tuning is correctly adapted, without in itself guaranteeing results.

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 arrangement of its blades all influence its aerodynamic behaviour. The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine management system. An increase in size can also alter the response time and the range dof optimal operation.

Reliability and balancing of the hybrid turbocharger

The documented 360° stop helps to distribute the axial forces exerted on the rotating assembly. The rotor is balanced at high speed, up to 150,000 rpm on a Cimat VSR test bench, in order to limit vibrations and mechanical stresses. However, this balancing does not compensate for incorrect installation or inadequate lubrication.

Engine remapping and preparation

The engine management system must be adapted for to make the most of the hybrid turbo’s characteristics. The mapping, boost pressure and wastegate settings must be checked during remapping. Depending on the configuration, the fuel injection, exhaust system, air dintake cooling, clutch or gearbox may also require checking or adjustment.

How do you identify the correct turbo?

Check the part number marked on the original turbo dand 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 (140 hp), the mountingYear and the engine code where available. An identical engine type does not always guarantee compatibility.
