OEM N54 N55 Continental HPFP Overdrive Kit – Master Link Edition

Unlock greater fueling headroom on your high-performance N54 build—without the complexity, cost, or compromises of traditional fueling upgrades. The master link chain eliminates the need to remove the front main seal or hub during installation, making it one of the simplest and most efficient upgrades available.

Where port injection, meth kits, and external overdrive systems add wiring, fuel lines, and potential failure points, this kit improves fueling performance with zero added components. It works by replacing the OEM vacuum pump sprocket on the oil pump chain with a precision-engineered smaller sprocket, increasing HPFP drive speed by 46%. A shorter, custom-spec oil pump chain—sourced from the same OEM supplier that manufactures BMW factory timing components—ensures proper tensioner operation and long-term reliability.

No extra moving parts. No electronics. Just pure mechanical efficiency with OEM-grade quality and a simplified install process.

Tested at sustained 8,000 RPM on high-output builds, this kit delivers 35%+ rail pressure increases and 15–20% VCV duty cycle reductions, providing the fueling confidence you need for high ethanol content or aggressive tuning—all while keeping the HPFP operating within its ideal range.

Important Installation Note – Please Read

To get the best results and protect your engine, we strongly recommend professional installation for this product and tuning is always recommended when you make a hardware change.

Because this is a performance upgrade, it’s important to know that it doesn’t come with any warranty or guarantee. Every car is a little different, and performance parts always carry some risk depending on the condition of the vehicle and how parts are installed. Please install carefully and at your own risk.

Special Reminder:
If your engine still has the original timing chain guides, they may have become brittle over time. Please take extra care when working around the chain and guides during installation. If any damage occurs, replacement of the timing components may be necessary.

We’re proud to deliver OEM-grade quality parts — but a careful, professional install is the key to getting the most out of them.

Thanks again for trusting BHP!
