This plug & play hybrid turbo is designed for the following engines Volvo 2.8 T with 272 hp, as documented at.. Depending on the tuning package selected, its specification combines a high-flow MFS compressor wheel, a 360° thrust bearing and internal modifications adapted to the increased air flow d.
The applications listed include, in particular, the Volvo S80 T6, TWIN S80 and XC90 T6. Compatibility must always be confirmed using the original turbocharger part number d.
Available upgrades — Stage 1, Stage 2 and Stage 3
Stage 1
Compressor wheel: MFS high-flow
Thrust bearing: 360° bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
This modification primarily affects the compressor impeller in order d to adjust the compression capacity and air flow rate d whilst maintaining the vehicle’s Installation without modification.
Stage 2
Compressor impeller: MFS high-flow oversized
dIntake casing: Reprofiled for accommodate the new impeller oversized
Thrust bearing: 360° bearing
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
The Stage 2 combines a oversized compressor wheel with a reprofiled d intake housing. This configuration is designed to increase air flow capacity d, with performance depending on the mapping and the overall engine set-up.
Stage 3
Compressor wheel: MFS high-flow oversized
Intake housing d: Reprofiled for to accommodate the new impeller oversized
Thrust bearing: 360° bearing
Turbine wheel: High-flow oversized
Turbine housing: Reprofiled for ly to accommodate the new impeller oversized
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench
This modification is carried out on both the compressor and turbine sides. The larger impeller dimensions and the re-profiling of the housings alter the flow capacity, but may also affect the response time and the range d'optimal operating range.
What is a hybrid 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 upgrade stage, modifications may involve the compressor wheel, the housings, the turbine wheel, the thrust bearing and the rotor 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, the machining of the housings and the overall coherence of the unit are decisive.
MFS compressor wheel: standard or ‘ Performance ’?
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This technology describes the manufacturing process and does not, on its own, guarantee an increase in air flow d.
A standard MFS impeller can retain a geometry equivalent to the original. An MFS Performance impeller has a geometry adapted to the modification, which may differ in particular in terms of the profile, height, width or diameter of the blades where such modifications are planned.
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. The impeller documented for for this product is made of forged aluminium; it is lighter, larger and taller than the d'original. The product data indicate an additional compression capacity of 15 per cent. Its use requires appropriate engine tuning.
Why does the geometry of the blades influence the air flow rate d?
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 under certain conditions, but the result also depends on the casings, the turbine, the boost pressure and the mapping. A larger impeller therefore does not automatically guarantee better performance and may alter the response time.
Reliability and balancing of the hybrid turbo
The documented 360° thrust bearing distributes axial forces over a wide surface area. The rotor is balanced at high speed, up to 150,000 rpm on a Cimat VSR test bench, to minimise vibrations and mechanical stresses. However, this balancing does not compensate for faults in assembly, lubrication or the presence d of a foreign object.
Engine remapping and preparation
The engine management system must be adapted for to make full use of the hybrid turbo’s characteristics. The mapping, boost pressure, injection, intake air cooling d and the exhaust must be checked or adjusted according to the modification. The wastegate must be adjusted when remapping the ECU. The transmission and other vehicle components must also be checked in line with the intended use.

Installation advice
⚠️ WARNING — IMPORTANT BEFORE INSTALLATION
Identify and rectify the cause of the previous fault. Carefully check the lubrication circuit, as well as the oil supply and return lines d. Check that the lines are clean, the inlet and that 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 further turbocharger failure.
How do you identify the correct turbo?
Check the part number marked on the turbo d the original, OEM and manufacturer part numbers, as well as the model, version, engine capacity, power output, production period and engine code. An identical engine may be fitted with several different turbocharger set-ups.
⚠️ 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 does not always guarantee compatibility.
If in doubt, please contact us with the part number clearly visible on your turbocharger.
