We’ll use the terms supercharger and blower interchangeably.
The centrifugal supercharger is very similar to a turbocharger, except the centrifugal supercharger is driven by a belt off the engine, while the turbocharger is driven by the force of the exhaust gases.
How does a blower work?
An impeller at the centre of the air blower sucks air and creates a spiral flow of air thereby creating a dynamic pressure that forces the air to flow through a curved path and out of the blower.
Where is the blower motor located in a car?
Find the blower-motor location in the repair manual. It is usually in the passenger-side footwell area, below the glove box. Vehicles built before the mid-late 1990s often have the blower motor located in the engine bay on the passenger side firewall, in plain sight.
What are the 3 types of superchargers?
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.
