This hybrid turbo for engine options Mercedes 2.7 CDI is based on an internal mechanism designed to adjust the flow rate d'air from the turbocharger'. The three levels on offer all use an MFS compressor wheel Performance, a 360° bearing stop and high-speed balancing.
The documented assignments relate in particular to Mercedes Class C, Class E, Class G and Class M models fitted with OM 612 engines.
This kit includes an MFS wheel Performance high flow rate with documented dimensions and a 360° stop. Its geometry is designed to adapt its range of motion d'air, without prejudging the engine’s final power output'.
The Stage 2 is fitted with a larger wheel and a casing d'the intake, reshaped accordingly'. This combination alters the aerodynamic characteristics of the compressor and can affect both its flow rate and its behaviour, depending on the conditions d'use'.
The Stage 2+ uses the largest dimensions of the three documented formulations. The wheel and the re-profiled wheel arch must be combined with a suitable engine configuration; a larger size alone does not guarantee better performance in all conditions.
A hybrid turbo retains a suitable turbocharger design for to receive internal components or machined parts that differ from the specification d'origin'. Depending on the modification, changes may relate to the compressor impeller, its dimensions, the geometry of the blades, the casings, the turbine impeller, the thrust bearing or the 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 impeller: the consistency between the components and the engine settings remains crucial.
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 that d'origin'.
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'. An MFS wheel Performance may use a blade diameter, profile or configuration suited to the preparation objective. A higher flow rate can deliver more power with the appropriate engine tuning, although this does not guarantee a performance gain.
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 result also depends on the compressor housing, the turbine, the boost pressure and the engine tuning. A larger wheel can also affect the response time and range d'optimal use'.
The documented 360° bearing stop distributes axial forces across the entire surface. The rotor is balanced at high speed – up to 150,000 rpm – on a Cimat VSR test bench in order to minimise vibrations and mechanical stresses. This balancing does not compensate for incorrect assembly or a lack of lubrication.
It may be necessary to adjust the engine management system for make the most of the turbo’s features. Mapping, boost pressure, fuel injection, intercooling, the exhaust system and the transmission must be checked in accordance with the level of tuning. The wastegate must be adjusted during fitting and remapping. A hybrid turbo does not automatically guarantee a performance gain without the right set-up.
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Identify and rectify the cause of the previous fault. Check the lubrication circuit, as well as the supply and return lines d'oil'. Check that the ducts and the intake are clean and free from foreign objects. Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions. The wastegate must be adjusted during engine installation and tuning. If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
Check the part number on the turbocharger d'origin', then compare the OEM and manufacturer part numbers. Also check the model, generation, body style, engine type, power output, production dates and engine code. Having the same engine is not always enough to confirm compatibility.
⚠️ Check your turbo’s part numbers
Before placing your order, Compare the part number on your turbocharger d'origin' using the references given in this fact sheet. 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.

A loss of power, an unusual whistling noise, oil consumption d, abnormal smoke or poor engine performance may be linked to a turbocharger fault.
However, a fault that appears to be turbo-related may also stem d from a lubrication issue, d from contaminated oil, d from a foreign object, from the intake or exhaust systems, or d from another engine peripheral component.
It is therefore important to investigate the cause of the fault before fitting a new turbo or a new Cartridge.
Since 2012, ALFI TURBO has been assisting private individuals and professionals in identifying and replacing turbochargers.
A turbocharger failure may be the result d of another engine problem. Before fitting d a new turbo or Cartridge, identify and rectify the cause of the original fault to d avoid d damaging the new part.
