Available tuning options — Stage 1, Stage 2 and Stage 3

What is a hybrid turbo?

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

The aim is d to adapt the compression capacity and the air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its impeller: the geometry of the components and how they are combined determine its behaviour.

MFS compressor wheel: standard or Performance?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This technology describes its manufacturing process, but does not in itself guarantee an increase in air flow rate d. A standard MFS wheel may retain a geometry equivalent to that d of the original.

An MFS wheel Performance can be given a geometry tailored to the tuning objective. For this product, the wheel is described as lighter, larger and taller than the d original, with an advertised 15 per cent increase in compression capacity.

A standard MFS impeller can be just as efficient 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 with appropriate engine tuning, though it does not in itself guarantee 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 the arrangement of its blades influence its aerodynamic behaviour and the volume d of 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 management system. A larger impeller therefore does not automatically guarantee better performance and may alter the response time as well as the range d of optimal operation.

Reliability and balancing of the hybrid turbo

The 360° bearing stop, documented at each stage, distributes the axial forces around the shaft. It helps the turbo adapt to operating stresses, without protecting it d from a lubrication fault or d from incorrect installation.

The rotating assembly 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 on the rotor.

Engine remapping and preparation

The engine mapping and boost pressure management must be adjusted for to make full use of the hybrid turbo’s characteristics. The wastegate must be adjusted whilst remapping the ECU.

Depending on the level of tuning, the fuel injection, exhaust, cooling, intake, clutch or transmission may also require checking or adjustment. Fitting the turbo alone does not guarantee any increase in power.

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 data sheet. Also check the make, model, generation, body style, engine type, power output ( hp), production period and engine code where available. An identical engine type does not always guarantee compatibility.

If in doubt, please contact us with the full part number of the original turbo d and the vehicle details.
