The useful comparison is between centrifugal superchargers such as ProCharger models and other designs, especially Roots and twin-screw superchargers. Which suits a car depends on its intended use, fitment, supporting hardware, and calibration.
What is the difference between a ProCharger and a supercharger?
A supercharger is a mechanically driven compressor that forces more air into an internal-combustion engine. ProCharger makes centrifugal superchargers; other manufacturers also make centrifugal units. In everyday conversation, people sometimes use “supercharger” to mean a Roots or twin-screw unit, but that usage is imprecise.
How the designs work
Centrifugal superchargers
A centrifugal supercharger uses a fast-spinning impeller to accelerate incoming air outward. The system converts that airflow into pressure, and boost generally builds as engine speed rises. ProCharger is one manufacturer of this design. The result depends on the specific unit, vehicle, system setup, and calibration.
Roots superchargers
A Roots supercharger uses lobed rotors to move air from the inlet toward the engine. It is a positive-displacement design commonly associated with boost arriving earlier in the rev range. It is not the same mechanism as a twin-screw supercharger.

Twin-screw superchargers
A twin-screw supercharger uses interlocking screws to move and compress air inside the housing. Like a Roots unit, it is a positive-displacement design, but the way it handles air differs.
Comparing centrifugal, Roots, and twin-screw designs
| Decision point | Centrifugal, including ProCharger | Roots | Twin-screw |
|---|---|---|---|
| How it moves air | An impeller accelerates air outward; the airflow is converted into pressure. | Lobed rotors move air toward the engine. | Interlocking screws move and compress air inside the housing. |
| Typical boost character | Boost generally increases with engine RPM. | Commonly associated with earlier boost response. | Commonly associated with earlier boost response. |
| Packaging and fit | Depends on the exact kit and engine bay. | Depends on the system and vehicle. | Depends on the system and vehicle. |
| Heat and intercooling | Intercooling and system design matter; no universal comparative result is established here. | Behavior depends on design and installation. | Behavior depends on design and installation. |
| Best way to choose | Compare the vehicle, intended use, response, supporting hardware, and calibration. | Compare the vehicle, intended use, response, supporting hardware, and calibration. | Compare the vehicle, intended use, response, supporting hardware, and calibration. |
These are design tendencies, not guarantees that every system will behave alike. Vehicle fitment, unit sizing, boost level, intercooling, and tuning all affect the result. The available research does not establish one design as best for every application.

Installation, fitment, and ownership
Installation time and modifications vary by vehicle and kit. ProCharger says most of its systems can be installed in 8–10 hours with simple hand tools, but that is the manufacturer’s general estimate, not an independent or universal labor quote. ProCharger also notes exceptions for race products and some options.
Do not assume that a system will fit, preserve factory components, or meet local emissions requirements just because it is the same general design. Engine and drivetrain loads, fuel use, warranty implications, and maintenance depend on the particular installation, calibration, and how the car is driven. Check the vehicle’s warranty and applicable emissions rules, and consult a qualified installer or tuner.

How to choose a supercharger for your car
- Define the use. Decide whether the car is primarily for street driving, drag racing, or track use, and what kind of response you want.
- Check exact fitment. Confirm compatibility with the vehicle, engine, and any relevant factory equipment for the specific kit.
- Review the complete system. Check what is included and what supporting fuel, engine, cooling, and drivetrain hardware may be required.
- Plan calibration and compliance. Discuss tuning with a qualified professional and verify emissions requirements and warranty terms before buying.
- Compare total ownership needs. Ask about installation, maintenance, and service for the particular system rather than assuming all units of one design are alike.
FAQ
Is a ProCharger a supercharger?
Yes. ProCharger is a brand, and its superchargers are centrifugal. A ProCharger is therefore a type of supercharger.
Is a ProCharger the same as a Roots blower?
No. A ProCharger centrifugal unit uses an impeller to accelerate air. A Roots blower uses lobed rotors to move air toward the engine.
