This hybrid turbo for motorisation Audi 2.7T benefits from d’an internal adjustment designed to regulate the flow rate’ d’air and compression capacity. Depending on the package selected, it comes with a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing on a Cimat VSR bench.
The applications documented include, in particular, the Audi A4 B5, A6 C5 and Allroad C5 petrol models from 230 to 265 hp. The benchmark for turbochargers dThe origin must be verified before any order is placed.
This unit combines a high-flow MFS compressor wheel with a 360° thrust bearing. It aims to adjust the flow rate d’air whilst retaining a design that is for one Installation without modification documented.
The wheel oversized requires the casing to be re-profiled d’admission’. This combination may affect the air flow rate and the behaviour of the compressor, subject to d’a consistent engine preparation programme’.
The documented characteristics for This course includes the MFS wheel oversized, crankcase re-profiling, 360° stop and VSR balancing. No precise increase in power can be deduced from these factors alone.
A hybrid turbo is based on a turbocharger design that has been adapted to accommodate modified internal components. Depending on the modification, changes may relate to the compressor impeller, its dimensions, the casings, the turbine impeller, the thrust bearing system or the balancing.
The aim is d’adjust the compression capacity and flow rate’ dair to meet the requirements of the preparation. A hybrid turbocharger is therefore not defined solely by the appearance of its compressor wheel: the consistency between the components and their mechanical compatibility remains a key factor.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This designation describes the manufacturing process, but does not in itself guarantee an increase in flow rate 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 intended application, particularly in terms of the profile, height, width or arrangement of the blades. 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. This additional flow rate can only be utilised with a suitable engine configuration.
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 right geometry can move more dair under certain conditions, but the result also depends on the casings, the turbine wheel, the boost pressure and the engine management system. A larger wheel does not automatically guarantee better performance and may affect response time.
The documented 360° bearing stop helps to distribute axial forces around the axis. 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. However, this balancing does not compensate for incorrect assembly or a lack of lubrication.
The farm dA hybrid turbo may require adjustments to the engine mapping, boost pressure, fuel supply and air cooling d’intake and exhaust’. The clutch, gearbox and other components must also be checked, depending on the vehicle and the level of modification. The wastegate must be adjusted correctly. Fitting the turbo alone does not guarantee a power increase.
Identify and rectify the cause of the previous fault. Check the lubrication circuit, as well as the supply and return lines doil. 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. Adjustments to the wastegate and engine management system should be carried out by a qualified professional.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
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 model, generation, body style, engine type and power output in hp, the assembly period and the engine code. Having the same engine is not always enough to confirm compatibility.
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 with the full part number from your turbocharger.

A single engine type may have been fitted with several different turbochargers depending on theYear, power output, engine version or technical evolution.. The application alone is therefore not always sufficient for to accurately identify the correct turbo.
Before ordering, note down the part numbers shown on the identification plate d of your old turbocharger. This may be d an OEM part number or d a part number from the turbo manufacturer.
Compare these part numbers with those listed on our product pages.. If in doubt, our team can help you verify the part number you are looking for before you place your order.
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.
