This hybrid turbo for engine variants 1.8 T benefits from d'an internal mechanism designed to adjust the flow rate' d'air and compression capacity'. Depending on the upgrade package chosen, it is fitted with a high-flow MFS compressor wheel, re-profiled housings and, on the most advanced specification, an impeller oversized.
The documented allocations relate to several models Audi, , Seat, , Skoda and Volkswagen ranging from 150 to 180 hp. The benchmark for turbochargers d'The origin must be verified before any order is placed'.
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 preparation acts primarily on the compressor wheel in order to d'adjust the flow rate' d'air, whilst maintaining the intended configuration' for one Installation without modification documented external.
Stage 2
Compressor wheel: High-capacity MFS oversized
Carter d'Admission:' Reprofiled for to receive the new wheel oversized
Stop: 360° bearing
Balancing: High speed at 150,000 rpm on a Cimat VSR test bench
The wheel oversized and the re-profiling of the casing d'admission requirements allow' d'adjust the airflow'. The result depends on the engine management system and the overall mechanical configuration.
Stage 3
Compressor wheel: High-capacity MFS oversized
Carter d'Admission:' Reprofiled for to receive the new wheel oversized
Stop: 360° bearing
Turbine wheel: High flow rate oversized
Turbine casing: Reprofiled for to receive the new wheel oversized
Balancing: High speed at 150,000 rpm on a Cimat VSR test bench
This version incorporates modifications to both the compressor and turbine sides. Oversizing may affect the available flow rate and response time; the choice of stage must therefore be consistent with the engine’s intended use and tuning..
What is a hybrid turbo ?
A hybrid turbo is based on an existing architecture that has been adapted for to receive different internal components. Depending on the modification, the changes may involve the compressor wheel, the turbine wheel, the casings, the thrust bearing or the 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: the geometry of the components and how well they fit with the housings are crucial.
MFS compressor wheel: standard or Performance ? ?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process does not, on its own, guarantee an increase in throughput d'air'. A standard MFS wheel can retain a geometry equivalent to that d'origin'.
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 wheel Performance may be given a profile or dimensions suited to the intended use, provided that such modifications are documented.
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 a larger wheel does not automatically guarantee better performance: the compressor housing, the turbine, the boost pressure and the engine management system all play a part in the outcome'.
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. This balancing does not compensate for a lack of lubrication or incorrect installation.
Engine remapping and tuning
Appropriate engine management is required for make the most of the hybrid turbo’s features. The mapping, boost pressure and wastegate setting must be checked. Depending on the level of preparation: fuel injection, exhaust, air cooling d'The intake, clutch or gearbox may also need to be checked or adjusted'. The editing d'A hybrid turbo alone does not guarantee a power boost'.

Assembly instructions
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLYBefore installation, identify and rectify the cause of the previous fault. Check the lubrication circuit, the supply and the return d'oil, the cleanliness of the pipes, as well as the intake and the absence of foreign objects'. 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 engraved or marked on the turbocharger d'origin', then compare the OEM and manufacturer part numbers. Also check the make, model, generation, engine type and power output in hp, theYear the mounting code and the engine code, where available.
⚠️ Check your turbo’s part numbersBefore 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 of your turbocharger d'origin'.
