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).

Mechanical
Belt (V-belt, Synchronous belt, Flat belt)
Direct drive
Gear drive
Chain drive

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.
