Spool FX-200 Gen1 B58 Upgraded High Pressure Pump

The Spool FX-200 Gen1 is a high-performance fuel pump designed to significantly enhance the fueling capabilities of BMW's B58 engine. It offers a substantial upgrade from the previous FX180 model, providing double the flow of the stock pump.

What is the FX-200?

The FX-200 is an upgraded high-pressure fuel pump specifically engineered for the BMW B58 motor. It features a larger bore size compared to the stock pump, delivering approximately twice the flow rate. This upgrade is fully E85 compatible and offers a plug-and-play installation with no need for cutting or splicing. The increased flow allows for the use of higher ethanol concentrations and supports fueling for larger turbochargers.

Why Do You Need It?

The stock high-pressure fuel pump (HPFP) on the B58 motor is limited in its capacity, especially when increasing engine output through tuning. The FX-200 effectively doubles the flow, elevating the fueling limits and enabling the use of bigger turbos and higher ethanol blends. This upgrade is essential for those looking to push their engine's performance to the next level.

Are Tune Changes Required?

Yes, calibration changes are necessary when installing the FX-200 pump. It's crucial to make these changes before starting the vehicle to avoid potential damage and warranty issues. Spool Performance can provide calibration details to your existing tuner or assist in connecting you with experienced tuners familiar with these pumps. Custom tuning is required to achieve optimal performance with the upgraded pump setup tailored to your vehicle and conditions.

Low Pressure Fuel Pump Upgrade

Proper low-pressure fueling is critical for the effective operation and longevity of high-pressure pumps and injectors in direct injection systems. Insufficient low-pressure fueling can lead to damage of the pump piston and bore due to inadequate lubrication. Ensure you plan your fuel system build with appropriate low-pressure upgrades to prevent damage and warranty issues.
