Yes, but Ford 2.5T is not supercharged but turbocharged.
Yeah sorry, I mixed the definition of super versus turbo charging as wkikipedia also does.

Some examples from wikipedia:
A supercharger is an air compressor used for forced induction of an internal combustion engine .
The greater mass flow-rate provides more oxygen to support combustion than would be available in a naturally-aspirated engine, which allows more fuel to be provided and more work to be done per cycle, increasing the power output of the engine.
Power for the unit can come mechanically by a belt, gear, shaft, or chain connected to the engine's crankshaft.
When power comes from an exhaust gas turbine a supercharger is known as a turbosupercharger[1] - typically referred to simply as a turbocharger. Common usage restricts the term supercharger to mechanically driven units.
And…..
Supercharger drive types

Superchargers are further defined according to their method of drive (mechanical—or turbine).
[edit] Mechanical
  • Belt (V-belt, Synchronous belt, Flat belt)
  • Direct drive
  • Gear drive
  • Chain drive
[edit] Exhaust gas turbines
  • Axial turbine
  • Radial turbine
And……
Supercharging versus turbocharging

Positive-displacement superchargers may absorb as much as a third of the total crankshaft power of the engine, and, in many applications, are less efficient than turbochargers. In applications for which engine response and power are more important than any other consideration, such as top-fuel dragsters and vehicles used in tractor pulling competitions, positive-displacement superchargers are very common.
There are three main categories of superchargers for automotive use:
  • Centrifugal turbochargers — driven from exhaust gases.
  • Centrifugal superchargers — driven directly by the engine via a belt-drive.
  • Positive displacement pumps — such as the Roots, Twin Screw(Lysholm), and TVS(Eaton) blowers.
