Procharger vs Vortech: Centrifugal Supercharger Showdown for the Challenger

Centrifugal Superchargers: The Basics

Centrifugal superchargers work like belt-driven turbochargers — an impeller spins at very high RPM (40,000–60,000+ RPM) to compress incoming air. Unlike roots/twin-screw positive displacement blowers that sit on the intake manifold, centrifugal superchargers mount to the engine block and use a remote charge pipe to route compressed air to the throttle body.

The result is a compact installation that doesn't require a hood scoop and produces a linear, RPM-climbing power delivery rather than the immediate full-boost hit of a roots blower.

Procharger: The Overview

Procharger has been making centrifugal superchargers for muscle cars since the early 1990s. They offer complete bolt-on kits for the 5.7L and 6.4L Challenger with everything needed for installation.

Stage 1 Kit (5.7L): Adds approximately 150–175 HP at the crank on a stock-fueled car running 8–9 psi

Stage 1 Kit (6.4L): Adds approximately 175–200+ HP at 8–9 psi

Complete kit price: $5,000–$6,500 depending on model

Procharger units use a self-contained oiling system — the supercharger has its own oil reservoir and does not tap into the engine's oil supply. This is a significant maintenance advantage: no oil lines to route, no concerns about engine oil supply to the blower.

Procharger sound: The signature high-pitched "whine and whistle" unique to centrifugal blowers — very different from the deep whine of a roots blower.

Vortech: The Overview

Vortech is Procharger's primary competitor in the centrifugal space, also with decades of history in the muscle car market.

V-3 Si Trim Kit (5.7L/6.4L): Similar power gains to Procharger at comparable boost levels

Complete kit price: $4,500–$6,000

The key difference: Vortech superchargers are gear-driven oiled units that tap the engine's oil supply through an adapter fitting. This eliminates the separate oil reservoir of the Procharger but requires careful oil line routing and means engine oil life is affected by the supercharger operation.

Vortech sound: Similar centrifugal whine, slightly different pitch than Procharger.

Direct Comparison

Power Delivery Character

Both deliver power that builds with RPM — unlike positive displacement blowers that are fully boosted from 1,500 RPM. Centrifugal boost builds from near zero at idle to maximum at redline. This means:

• Milder behavior off idle — easier to drive on the street
• Power delivery rewards revving the engine
• Less initial launch traction advantage than a roots blower
• Better top-end power than most roots blowers at equivalent boost levels

Which Should You Choose?

Procharger if: You prefer the self-contained oiling system simplicity, or your tuner has more Procharger experience.

Vortech if: The price point is a factor, or you prefer their specific power delivery character.

Both are excellent products with strong dealer/tuner support networks. The choice often comes down to which your local tuner has more experience with — a well-tuned Vortech will always outperform a poorly tuned Procharger, and vice versa.
