This hybrid turbocharger is designed for for direct fitment on the applications documented at Volvo. Its specification combines a high-flow MFS compressor wheel, a 360° bearing retainer and high-speed balancing, with additional modifications depending on the chosen performance stage.
Applications include, amongst others, the Volvo 850 T5, C70, S70 T5 and V70 T5. The part number of the original turbo d must be checked before placing an order.
This modification primarily affects the compressor section in order d to adapt the flow rate d to the air. The 360° thrust bearing helps to distribute axial forces more evenly during operation.
Stage 2 is fitted with a oversized compressor impeller and a d intake housing adapted to. This combination is designed to alter the compression capacity and air flow rate d, with performance depending on the engine configuration.
This version modifies the compressor and turbine sides. The sizing of the impellers and the re-profiling of the housings influence the flow rate, load ramp-up and d the optimal operating conditions of the turbocharger.
A hybrid turbo is based on a turbocharger architecture adapted for accommodate internal components that differ from the original configuration d. Depending on the stage, modifications may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing and the balancing.
The aim is d to adapt the compression capacity and the d air flow. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the wheels, the machining of the housings and the overall balance are crucial.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This is d a manufacturing process which, on its own, does not guarantee an increase in air flow d.
A standard MFS impeller may retain a geometry equivalent to the original. An MFS impeller Performance may adopt a geometry adapted to the modification, particularly through its profile, dimensions or the configuration of its blades, where such modifications are intended.
A standard MFS impeller can be just as glossy 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, on its own, guarantee a specific result.
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. A suitable geometry can move more d air within certain operating ranges.
The result also depends on the housings, the turbine wheel, the boost pressure and the engine tuning. A larger turbine wheel therefore does not automatically guarantee better performance and may alter the turbo’s response time.
The 360° thrust bearing fitted to each documented stage distributes axial forces over a wide surface area. However, it does not protect the turbocharger against a lack of lubrication, contamination or incorrect installation.
The 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.
The engine management system must be adapted for to make full use of the hybrid turbo’s characteristics. The wastegate must be adjusted during the ECU reprogramming.
Depending on the level of tuning, the fuel injection, exhaust system, cooling, boost pressure and transmission must be checked or adjusted. Fitting the turbo does not automatically guarantee a power gain without appropriate engine configuration.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Check the lubrication circuit, the oil supply and return d, and ensure all pipes are clean.
Check the inlet for any foreign objects. Prime the system in accordance with the applicable guidelines and follow the manufacturer’s instructions.
A lubrication fault that is not rectified may lead to further failure of the turbocharger.
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, version, engine type, power output, mountingYear and engine code where available.
A similar engine may be fitted with several different turbo set-ups depending on the version or production period.
⚠️ Check your turbo’s part numbers
Before ordering, compare the part number marked on your original turbo d with the part numbers listed in this specification sheet. An identical engine does not always guarantee compatibility.
If in doubt, please contact us with the full part number from your turbo.

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.
