Stage II Intercooled Supercharger System for 15-19 Challenger R/T Scat Pack 6.4L & SRT 392 HEMI 1DG415-SCI By ProCharger

Ready to slap some serious horsepower onto your ride without hacking it to pieces? Enter: the ProCharger Stage II Supercharger System—your gateway to 1200+ HP (with the right upgrades) and zero compromises. It’s like feeding your engine a steady diet of jet fuel… but, you know, legally.

At the heart of the system is the legendary P-1SC-1 head unit, known for its self-contained oiling (no messy oil lines or awkward engine taps). Whether you’re just looking to spice up your daily driver or build something that terrifies tires and passengers alike, this kit’s got your back. And your front. And probably your transmission, too.

Now here’s where things get real spicy: the new 8-rib dedicated belt drive. This setup means more grip, more consistency, and less belt slip—aka more boost, more power, and fewer headaches. It’s like giving your supercharger a bear hug made of belts. Plus, it uses a high-performance balancer to make sure things stay smooth even when you’re pushing serious PSI.

Worried about cooling? Don’t be. You’ve got the option of a standard 423 in³ intercooler or the massive 970 in³ race intercooler—both designed to slide right behind your bumper without needing to cut, trim, or bribe your body panels.

Best part? The mounting bracket fits all the way up to the F-1A-94 head unit, so this kit grows with your build. Want 800 HP today and 1200 HP tomorrow? No problem. Just upgrade the head unit and internals—and maybe warn your neighbors.

Track-ready. Street-worthy. No sawzall required. What more could you ask for?
