This hybrid turbocharger is designed for for the petrol engines Smart 0.6 i and 0.7 i documented at.. Depending on the specification chosen, it is fitted with a high-flow MFS compressor wheel Performance, a 360° bearing stop and high-speed balancing on a Cimat VSR test bench.
The applications listed include the Smart Cabrio and City-Coupé 450, Crossblade 450 and Roadster 452, with power outputs ranging from 45 to 75 hp depending on the version.
This set-up is based on a high-flow MFS compressor wheel. Its geometry is designed to adapt the compressor’s air displacement capacity d, subject d to a consistent engine configuration and d tuning.
The Stage 2 combines a larger impeller with a re-profiled intake housing d. This modification is designed to ensure the new geometry functions correctly and may alter the air flow rate d as well as the turbocharger’s behaviour.
A hybrid turbo retains a turbocharger architecture designed for to accommodate modified internal components. Depending on the modification, changes may relate to the compressor wheel, its dimensions, the geometry of the blades, the housings, the thrust bearing or the balancing.
The aim is d to adapt the compression capacity and air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its impeller: consistency between the components, their geometry and their settings is essential.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone does not guarantee an increase in airflow d. A standard MFS wheel may retain a geometry close to the original.
A standard MFS impeller can be just as shiny 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. An Performance impeller can have a specific diameter, profile or blade configuration when these characteristics are documented. A higher flow rate can contribute to power output with appropriate engine tuning, though it does not in itself guarantee a gain.
The compressor impeller draws in and then compresses the air sent to the engine. Its diameter, profile, height, width and blade arrangement all influence its aerodynamic behaviour. The result also depends on the compressor housing, the turbine section, the boost pressure and the engine tuning. A larger impeller therefore does not automatically guarantee better performance and may alter the response time or the operating range d Optimal use.
The documented 360° thrust bearing helps to distribute the axial forces exerted on the rotating assembly. The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench to minimise vibrations and mechanical stresses. This balancing does not compensate for incorrect installation, inadequate lubrication or the presence d of a foreign object.
Adjustments to the engine management system may be necessary for to make the most of the hybrid turbo’s characteristics. The mapping, boost pressure, fuel injection, exhaust, cooling and, depending on the vehicle, the transmission must be checked or adjusted. The wastegate must be adjusted during fitting and remapping. No power gain is automatic without a coherent configuration.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault be d' installing the turbocharger.
Check the lubrication circuit, the oil supply and return d. Also check that the pipes and the inlet are clean and free from foreign objects.
Carry out the priming procedure in accordance with the applicable recommendations and follow the manufacturer’s instructions. The wastegate and engine management system must be adjusted to suit the vehicle’s specification.
Unresolved lubrication issues may lead to the turbocharger failing again.
Check the part number marked on the original turbo d, then compare the OEM and manufacturer part numbers.. Also check the model, generation, body style, engine type, power output at hp, fitment dates and engine code.. An identical engine type is not always sufficient to confirm compatibility.
⚠️ 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 specification does not always guarantee compatibility.
If in doubt, please contact us with the part number clearly visible on your original turbocharger d.

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.
