If you're looking to take your BMW E46 M3 to the next level, let me tell you about the PRIMA PLUS supercharger system from Active Autowerke. This isn't just any supercharger; it's a beast that can push you over the 500 WHP mark using good ol' pump gas with 93 octane. That’s right—no need for race fuel here. This upgrade kit builds on the already impressive PRIMA system, designed specifically for those of us who crave more power.

Working closely with Frank Smith from Tuning Tech FS, this kit has gone through its paces. We’re talking countless hours of dyno runs, meticulous data logging, and fine-tuning to ensure it performs like a champ. So, you know it’s been tested by folks who really understand what it means to enhance a BMW.

The PRIMA PLUS features a centrifugal design, which is pretty standard, but what sets it apart is its variable boost settings—9.0 psi and 9.5 psi. That flexibility means you can dial in your power just the way you like it. For context, a stock E46 M3 rolls in at around 265 WHP. With the PRIMA SC, you're looking at 425 WHP, and the PRIMA PLUS? Well, it pushes that number to over 500 WHP. That’s a serious upgrade!

How does it all come together? The PRIMA PLUS operates without a front-mounted intercooler, relying instead on a Water/Methanol system and some precise tuning. When you flip the switch, it cranks up to 9.5 psi of boost and delivers that 500+ WHP. And don’t worry about potential hiccups—if there’s ever an issue like low fluid levels or detonation, the system has a built-in safeguard that drops the boost back to 6.0 psi to protect your engine.

Active Autowerke is all about reliability and performance, so you can feel confident diving into the forced induction scene with them. Here’s what you can expect:

• Dyno results are based on a stock motor running 93 octane.
• The car's got some exhaust mods—headers, section 1, and a rear exhaust—so keep that in mind.

Features worth noting:

• A complete Water/Methanol system that’s ready to go.
• Trunk-mounted WA tank with a solid holding base.
• A durable WA pump with internal seals and nozzles designed for methanol.
• Non-intrusive mounting that keeps your trunk space intact (except for convertibles).
• Integrated wiring with fail-safe features to keep everything running smoothly.
• Custom software tuning to match your boost levels perfectly.
• Runs on 93 pump octane—no need for high-octane race fuel.
• Comes with detailed step-by-step instructions for installation.
