This hybrid turbo – for, with a 1., 9 dCi – features da mechanical upgrade designed to optimise air flow d. Depending on the package chosen, it includes a high-flow MFS compressor wheel, re-profiled casings or even a turbine wheel oversized.
The documented applications cover several versions of the Renault: Mégane III, Mégane Coupé, Mégane Grandtour, Scénic III and Grand Scénic.
This configuration combines a high-flow MFS compressor wheel with a 360° thrust bearing. It is designed to adjust the compression capacity and air flow rate dwhilst maintaining the vehicle’s documented dInstallation without modification configuration.
The Stage 2 features a oversized compressor impeller and a reprofiled dintake casing. This combination en dly accommodates the new geometry and can alter both the air displacement capacity and the compressor’s performance.
This modification is carried out on both the compressor and turbine sides. Both housings are re-profiled for accommodate the oversized impellers documented at. The result, however, depends on the overall engine configuration and its settings.
A hybrid turbo is based on a turbocharger architecture adapted to accommodate modified internal components. Depending on the upgrade stage, the modifications may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system and balancing.
The aim is dto adapt the compression and air flow dto the requirements dof an engine upgrade. A hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the wheels, their combination with the housings and the quality of the balancing are also crucial.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This technology describes a manufacturing process and does not, on its own, guarantee an increase in air flow rate d.
A standard MFS impeller may retain a geometry equivalent to that of the original d. A Performance MFS impeller may adopt a geometry adapted to the modification, for example a different profile or dimensions, provided these modifications are documented.
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. A higher airflow can contribute to power output with appropriate engine tuning, though it does not in itself guarantee results.
The compressor impeller draws in and then compresses the intake air. Its diameter, profile, height, width and the arrangement of its blades influence the compressor’s aerodynamic behaviour. A suitable geometry can move more dair under certain operating conditions.
The result also depends on the compressor housing, the impeller and the turbine housing, the boost pressure and the engine set-up. A larger impeller therefore does not automatically guarantee better performance and may alter the response time as well as the range dof optimal operation.
The 360° bearing stop present on all three stages helps to distribute axial forces around the shaft. It does not eliminate the need dfor a clean, functional and properly primed lubrication system.
Each documented modification undergoes high-speed balancing at 150,000 rpm on a Cimat VSR test bench. This process aims to minimise vibrations and mechanical stresses on the rotor, without compensating for assembly errors or lubrication faults.
An adjustment to the engine management system is required for to make full use of the hybrid turbo’s characteristics. The mapping, boost pressure and wastegate setting must be adjusted during remapping. Depending on the modification, the fuel injection, exhaust system, air cooling d, intake system, clutch or gearbox may also require checking or adjustment. The hybrid turbo alone does not guarantee a power increase.
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault before d’install the turbo.
Check the lubrication circuit, the oil supply and return lines, and ensure all pipes are clean d.
Check the intake and ensure there are no foreign objects. Prime the system in accordance with the applicable recommendations and follow the manufacturer’s instructions.
A lubrication fault that is not rectified may lead to the turbocharger failing again.
Check the part number engraved or marked on the original turbo d, then compare the OEM and manufacturer part numbers.. Also check the make, model, generation, body style, engine type, power output at hp, production period and engine code where available. An identical engine type does not always guarantee 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 data sheet. An identical engine specification does not always guarantee compatibility.
If in doubt, please contact us with the full part number of your original turbo 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.
