F-1A-94 Supercharger Head Unit PC336A-001 By ProCharger

So, your current ProCharger setup just isn’t scratching that horsepower itch anymore? Sounds like it’s time to level up! Meet your new best friend: the ProCharger P-1 or D-1 Supercharger Head Unit—the perfect upgrade for HO or Stage 2 kits when you’re ready to ditch “mild” and go full “wild.”

This bad boy comes as a head unit only, so don’t expect any brackets or pulleys—just the high-powered heart of your next build. It’s kind of like ordering a steak without the sides—still delicious, still powerful, just BYO-potatoes (or in this case, pulley and mounting hardware).

Whether you’re chasing that elusive dyno number, trying to surprise a few unsuspecting supercar owners, or just want your engine bay to look like it means business, this upgrade will get you there. The P-1 and D-1 series superchargers are built for serious performance—more airflow, more boost, and yes… more bragging rights.

Keep in mind, this isn’t a beginner’s bolt-on. This is for the folks who already have an HO or Stage 2 ProCharger kit and are ready to crank it up to eleven. If you’re still stock? Start with a tuner kit first—don’t skip leg day.

So if your ride is whispering, “I need more boost,” don’t ignore it. Give it what it wants. And then hold on.
