This hybrid turbo for engine variants 1.9 DTI is based on an architecture designed for in-house processing aimed at increasing throughput d'air'. Depending on the upgrade package chosen, it is fitted with a high-flow MFS compressor wheel, a 360° bearing retainer and additional modifications to the casings or the turbine section.
The documented assignments relate in particular to several Renault Espace, Kangoo, Laguna, Mégane and Scénic, as well as the Volvo S40 and V40. Compatibility must always be confirmed using the turbo’s part number d'origin'.
Available products — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: High-capacity MFS
Stop: 360° bearing
Balancing: high speed at 150,000 rpm on a Cimat VSR test bench
This product acts mainly on the compressor section. The high-flow MFS wheel is designed to adjust the compression capacity and volume d'air displaced, without change' d'the announced installation'.
Stage 2
Compressor wheel: High-capacity MFS oversized
Carter d'Admission:' re-profiled for to receive the new wheel oversized
Stop: 360° bearing
Balancing: high speed at 150,000 rpm on a Cimat VSR test bench
The Stage 2 incorporates a compressor wheel oversized to a casing d're-profiled intake'. This mechanical modification enables d'to accommodate the new wheel and may alter the flow rate' d'air and the behaviour of the compressor'.
Stage 3
Compressor wheel: High-capacity MFS oversized
Carter d'Admission:' re-profiled for to receive the new wheel oversized
Stop: 360° bearing
Turbine wheel: high-speed oversized
Turbine casing: re-profiled for to receive the new wheel oversized
Balancing: high speed at 150,000 rpm on a Cimat VSR test bench
The Stage 3 includes documented modifications to the compressor and turbine sections. The result depends on the overall engine set-up; a larger wheel alone does not guarantee better performance in all conditions.
Understanding hybrid preparation
What is a hybrid turbo ?
A hybrid turbo retains a turbocharger design compatible with its intended applications, whilst incorporating internal modifications. Depending on the course, these may cover the compressor wheel, the casings, the turbine wheel, the thrust bearing and balancing.
The aim is d'adjust the compression capacity and flow rate' d'air'. However, a hybrid turbo is not defined solely by the appearance of its impeller: its geometry, the machining of the housings and the overall coherence of the assembly are crucial.
MFS compressor wheel: standard or Performance ? ?
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 throughput' d'air'.
A standard MFS wheel can retain a geometry equivalent to the original. An MFS wheel Performance may be designed with a geometry suited to the intended purpose, for example with a different profile or dimensions where such modifications are envisaged.
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'. The fact sheet d'The source states' for The MFS wheel features a forged aluminium design, which is lighter, wider and taller than the original, with 15 per cent more compression.
Why does the geometry of the blades affect the flow rate? d'air?' ?
The compressor wheel draws in and then compresses the air. 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 conditions, but the result also depends on the casings, the turbine, the boost pressure and the engine tuning'. An increase in size may also affect the response time and the range d'optimal use'.
Reliability and balancing of the hybrid turbocharger
The documented 360° stop distributes axial forces over a wide area. 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 protect the turbocharger against incorrect fitting, inadequate lubrication or the presence of d'a foreign body'.
Engine remapping and tuning
Making use of characteristics d'A hybrid turbo may require adjustments to the engine mapping, boost pressure and wastegate'. Depending on the level of preparation: fuel injection, exhaust, air cooling d'The intake, clutch or gearbox must also be checked or adjusted'. A hybrid turbo does not automatically guarantee a power boost without the right set-up.

Assembly instructions
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Search for and correct the cause of the previous failure. Check the lubrication circuit, the supply and the return d'oil, as well as 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.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
How do you choose the right turbo ?
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, generation, body style, engine type, power output, theYear the mounting code and the engine code, where available.
The fact that two motors are identical does not always guarantee compatibility, as there may be several different configurations.
⚠️ 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 in doubt, please contact us, quoting the reference number clearly visible on the plate dIdentifying your turbocharger.
