This hybrid turbocharger, designed for engines Volvo 2.4 and 2.5 is fitted with an internally designed assembly for adjust the compression capacity and flow rate d'air'. Depending on the package chosen, it includes a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing.
The documented assignments include, in particular, the following: Volvo 850, C70, S60, S70, S80, V70 and XC70. The vehicle specification and the turbo part number d'Origin must be checked before placing an order'.
This preparation acts on the compressor wheel in order to d'adjust the flow rate' d'air'. The 360° stop helps to distribute axial forces, whilst rotor balancing is designed to minimise vibrations at high speeds.
The wheel oversized requires the casing to be re-profiled d'admission'. This combination may affect the compressor’s flow capacity and behaviour, with the result depending on the motor control system and other peripheral devices.
The documented characteristics for This version includes an MFS wheel oversized and a casing d're-profiled intake'. The choice of work placement must be determined on the basis of the driving project and the conditions d'intended uses'.
A hybrid turbo is based on a specially adapted turbocharger design for to receive internal changes. Depending on the specific application, these may relate to the compressor wheel, its dimensions or geometry, the casings, the impeller, the thrust bearing system and the balancing process.
The aim is d'adjust the compression capacity and flow rate' d'tailored to the project's requirements'. However, a hybrid turbocharger is not defined solely by the appearance of its impeller: the consistency between the components and their mechanical compatibility is crucial.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This term describes a manufacturing process and does not, in itself, guarantee an increase in flow rate d'air'.
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, for example a specific profile, diameter or blade configuration, 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 d'air'. A higher flow rate can contribute to power development when combined with the right engine tuning, although it does not, on its own, guarantee results.
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 d'air under certain operating conditions'.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine tuning. A larger wheel therefore does not automatically guarantee better performance and may affect response time as well as the range d'optimal use'.
The 360° bearing stop, as covered in the three training courses, helps to distribute the axial forces around the axis. It does not exempt d'proper lubrication nor d'a compliant assembly'.
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 stresses, but does not protect the turbocharger against incorrect fitting, contamination or a fault d'oil supply'.
It may be necessary to adjust the engine management system for make the most of the hybrid turbo’s features. The mapping, boost pressure and wastegate setting must be configured according to the set-up.
Depending on the level of preparation, injection, fuel supply and air cooling d'The intake, exhaust, clutch or transmission may also require checking or adjustment'. The editing d'A hybrid turbo does not automatically guarantee a power boost without proper preparation'.
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Before installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the supply and the return d'the oil and the cleanliness of all the pipes'.
Check the intake and ensure there are no foreign objects present. Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions. Wastegate adjustment and engine modifications must 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 d'origin and compare it with the OEM and manufacturer part numbers listed on this sheet'. Also check the make, model and engine type 2.4 or 2.5, the power in hp, theYear installation details and, where available, the engine code.
The same engine can be fitted with several different turbocharger set-ups. The reference number shown on the plate d'Identification therefore remains the main point of comparison'.
⚠️ 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 with the full reference number shown on 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.
