Description

This hybrid turbocharger, designed for the 110 hp 2.5D engine, is engineered for for installation plug & play without the need for any modifications during fitting. Depending on the chosen upgrade package, the modification may involve the compressor wheel, the housings or the turbine section.

The high-flow MFS compressor impeller, the 360° thrust bearing and the documented high-speed balancing are designed to adapt the compression capacity and air flow d to the requirements d of a coherent engine tuning programme.

Available tuning packages — Stage 1, Stage 2 and Stage 3

Stage 1
Compressor wheel: MFS high-flow
Thrust bearing: 360° bearing
Balancing: High-speed at 150,000 rpm on a Cimat VSR test bench

This modification primarily affects the compressor impeller to d adapt the flow rate d to the air, whilst retaining a configuration designed for for direct mounting.

Stage 2
Compressor wheel: MFS high-flow oversized
Intake casing d: 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

Stage 2 combines a oversized compressor wheel with a reprofiled housing d'admission. This modification can increase air flow capacity d, with performance depending on the engine management system and the overall configuration.

Stage 3
Compressor wheel: MFS high-flow oversized
Intake housing d: Reprofiled for to accommodate the new impeller oversized
Thrust bearing: 360° bearing
Turbine impeller: High-flow oversized
Turbine casing: Reprofiled for ly to accommodate the new impeller oversized
Balancing: High-speed balancing at 150,000 rpm on a Cimat VSR test bench

Stage 3 is applied to the compressor and turbine sides. The oversized turbine impeller and the reprofiled turbine housing alter the turbo’s operating characteristics; the result therefore depends on the engine as a whole, the mapping and the associated peripherals.

What is a hybrid turbo?

A hybrid turbo is based on a turbocharger architecture adapted for to accommodate internal components that differ from the original configuration d'. Depending on the upgrade stage, the modification may involve the compressor wheel, the turbine wheel, the housings, the thrust bearing system or the balancing.

The aim is d to adapt the compression capacity and the air flow rate d. However, a hybrid turbo is not defined solely by the appearance of its compressor wheel: the geometry of the wheels, the machining of the housings and the overall coherence of the assembly are decisive.

MFS compressor wheel: standard or ‘ Performance ’?

MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process alone does not guarantee an increase in air flow rate d'air. A standard MFS wheel may retain a geometry equivalent to that d'of the original.

For this product, the high-flow MFS impeller is specified as being made of forged aluminium, lighter, larger and taller than the original impeller d. The technical data sheet states that this configuration provides 15 per cent additional compression, though this does not constitute a guarantee of increased engine power.

A standard MFS impeller can be just as effective 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 only when combined with appropriate engine tuning.

Why does the geometry of the blades influence the air flow rate d?

The compressor wheel 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 and its ability to move air under different operating conditions.

The result also depends on the casings, the turbine wheel, the boost pressure and the engine. A larger wheel does not automatically guarantee better performance and may alter the response time as well as the optimal operating range d.

Reliability and balancing of the hybrid turbo

The 360° bearing thrust ring fitted to each stage helps to distribute the axial forces exerted on the rotating assembly. It does not eliminate the need d for proper lubrication or compliance with fitting requirements.

The rotor is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. This balancing is designed to minimise vibrations and mechanical stresses, but does not protect the turbocharger against incorrect installation, inadequate lubrication or the presence d of a foreign object.

Engine remapping and tuning

The engine management system must be adapted for make full use of the characteristics d a hybrid turbo. The wastegate must be adjusted when remapping the ECU.

Depending on the level of tuning, it is also advisable to check or d'adjust the fuel injection, boost pressure, exhaust system, cooling system, intake system and, if necessary, the transmission. Fitting d'a hybrid turbo does not automatically guarantee a power gain without a coherent configuration.

Installation tips

⚠️ WARNING — IMPORTANT BEFORE INSTALLATION

Identify and rectify the cause of the previous fault before d installing the turbo. Check the lubrication circuit, the oil supply and return d as well as the cleanliness of all pipes.

Check the intake and ensure there are no foreign objects present. Carry out the priming procedure in accordance with the applicable recommendations and follow the vehicle manufacturer’s instructions.

Failure to rectify a lubrication fault may result in the turbocharger failing again.

How do you identify the correct turbo?

Check the part number marked on the original turbo d, then compare it with the OEM and manufacturer part numbers in this data sheet.. Also check the model, generation, body style, engine type, power output ( hp), years of manufacture and the engine code where available. 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, contact our team with the part number clearly visible on your original turbo d.

Turbo failure: identify the cause before replacement

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.
