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 relate to the compressor wheel, the turbine wheel, the casings, the thrust bearing or the balancing of the rotor.

The aim is d’adjust the compression capacity and flow rate’ d’air to meet needs dengine tuning. However, a hybrid turbocharger is not defined solely by the appearance of its compressor wheel: the geometry of the wheels, the machining of the housings and the overall coherence of the assembly are all crucial factors.

MFS compressor wheel: standard or Performance ? ?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This designation describes a manufacturing process and does not, in itself, guarantee an increase in throughput dair.

A standard MFS wheel can retain a geometry equivalent to that d’origin’. An MFS wheel Performance may be designed with a geometry suited to the application, with a specific profile, height, width, diameter or blade arrangement, where such modifications are intended.

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. The technical description provided for This product features a forged aluminium wheel, which is lighter, larger and taller than the one d'Original', with an additional 15 per cent compression. However, the use of this capacity depends on d’suitable engine preparation’.

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, the profile of the blades, their height, width and arrangement all influence the aerodynamic behaviour of the compressor.

The right geometry can move more d’air 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 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, as documented in the three training courses, helps to distribute the axial forces around the turbocharger’s axis. It does not exempt d’a lubrication system in perfect working order, nor d’a compliant installation’.

The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This procedure is designed to minimise vibrations and mechanical stress, but does not protect the turbocharger against incorrect installation, inadequate lubrication or the presence of foreign objects.

Engine remapping and tuning

A hybrid turbo may require adjustments to the engine mapping and boost pressure control. The wastegate must be adjusted when the ECU is remapped.

Depending on the level of preparation required, the fuel injection, exhaust and air cooling systems d’The intake, clutch or gearbox may also need to be checked or adjusted’. The editing dA hybrid turbo does not automatically guarantee a power boost without the right set-up.

How do you choose the right turbo ?

Check the part number marked on the turbocharger dthe original, then compare it with the OEM and manufacturer’s part numbers listed on this sheet. Also check the make, model, generation, engine type and power output in hp, the assembly period and the engine code, where available.

The same engine can be fitted with several different turbocharger set-ups. Comparing product specifications therefore remains the most reliable method d’identify the correct configuration’.

If in doubt, please contact us, quoting the reference number clearly visible on the plate or casing of your turbocharger.
