Upgraded Turbocharger
manufactured using CNC lathes and machining centers
All our modifications are performed on a CNC lathe to ensure maximum precision and quality.
Balancing Bench
The turbo balancing bench represents the best technology to ensure the perfect functionality of the turbine according to the OEM parameters provided by the manufacturer.
Dynamic Flow Bench
Our technicians use CIMAT balancing and flow benches that guarantee the perfect functionality of the turbocharger.
Our dynamic test bench, in addition to geometry adjustment as performed in common static test benches, allows the measurement (and adjustment) of numerous additional parameters that can cause – if poorly adjusted – failures and malfunctions in reconditioned turbines.
Adjustments are performed based on a database with over 1000 continuously updated turbo codes based on values provided by the turbocharger manufacturer.
The bench uses patented TurboTest technology and features the Rotortest 610 measurement system, whose values are displayed on a touch-screen monitor through which the operator can print the balancing and flow certificates that accompany our turbines.
The dynamic test bench allows for:
| Electronic and pneumatic actuator adjustment |  |
|---|---|
| Verification of flow dispersion on the turbine side | |
| Verification of correct coupling between turbine impeller, geometry, and turbine housing | |
| Verification of correct coupling between compressor impeller and compressor housing | |
| Verification of correct impeller dimensions | |
| Verification of compressor side compression ratio | |
| Verification of whistling noise | |
| Verification of oil leakage in pressure gradient conditions similar to operating conditions | |
| Verification of compressor side compression ratio | |
IMPORTANT
The installation of an upgraded turbo must be performed by specialists in the field with professional equipment.
To achieve the indicated horsepower gain, it is necessary to intervene on other vehicle components, such as the injection control unit, pump, injectors, intercooler, exhaust system (and, where necessary, methanol).
N.B.
Before purchase, approximate measurements are provided to the customer to choose the type of modification. Technical details and exact component measurements will be provided to the customer after purchase.

Certified Quality
Balancing tests based on models performed up to 300,000 rpm.
Dynamic flow tests and performance tests.
Customization
Possibility of custom coloring for the intake housing with high-temperature paints.
The alloy is mainly composed of Copper with additions of magnesium and manganese, and its particular processing ensures that all normally present oxidation defects are eliminated.
Subsequent heat treatment gives Avional physical characteristics comparable to carbon steels.
MFS Avional impellers are manufactured on 5-axis CNC machining centers that achieve high speeds to create aerodynamic blades offering much higher performance than traditional ones and do not use molds, which over time produce impellers with increasing tolerances compared to the design.
These technological solutions offer the best solution to the engineering specifications required by a modern modified turbocharger.
