Superchargers, Turbochargers and Procharger What’s Best?
ProCharger vs. Supercharger: What’s the Difference and Which Is Right for You?
If you're considering forced induction for your vehicle, you’ve likely come across two popular options: the ProCharger centrifugal supercharger and traditional positive-displacement superchargers like Roots or twin-screw types. Both systems increase horsepower by compressing air into the engine—but they do it in different ways, and each has its advantages.
🧠 How Superchargers Work
Unlike turbochargers, which are powered by exhaust gases, both ProChargers and traditional superchargers are driven mechanically by the engine’s crankshaft. This means you get immediate throttle response without lag. The difference lies in how they deliver boost and how that affects your vehicle's performance.
⚙️ Comparing Supercharger Types
Positive-Displacement Superchargers (Roots & Twin-Screw)
- ✅ Deliver full boost almost instantly at low RPMs
- ⚠️ Typically larger and require more space under the hood
- ❌ Boost can taper off at higher RPMs
Centrifugal Superchargers (ProCharger Style)
- ✅ Boost increases with RPM—similar to how a turbocharger feels
- ✅ More compact and easier to package in tight engine bays
- ✅ Typically includes intercooling and self-contained oiling
- ⚠️ Less boost at lower RPMs compared to Roots/twin-screw
🔍 Key Differences to Consider
| Feature | Positive-Displacement | Centrifugal (ProCharger) |
|---|---|---|
| Throttle Response | Immediate, strong low-end torque | Progressive boost with RPM |
| Power Delivery | Peaks early, may taper at high RPM | Smooth, linear build to redline |
| Size & Packaging | Larger, top-mounted systems | Compact, side-mounted options |
| Install Complexity | Often requires hood clearance mods | Typically fits under stock hoods |
| Cooling | May or may not include intercooling | Usually includes air-to-air intercoolers |
💡 Which System Is Best for You?
The right supercharger depends on your goals, driving style, and vehicle setup:
- If you want immediate low-end power and are okay with a bulkier install, a positive-displacement supercharger could be the right fit.
- If you’re looking for smoother power delivery, better high-RPM performance, and easier packaging, a ProCharger-style centrifugal system is worth considering.
