Spool Performance is proud to introduce our flag-ship 200 bar high-pressure fuel pump. The FX400 improves on our existing industry leading FX200 by about 20% across the entire delivery range. 

The FX400 coupled with our IFX150 Gen1 DI injectors is a true revolution and the key to DI only high horsepower numbers on the Gen1 BMW high-pressure fuel system.

 

What is the FX-400?

The FX-400 is our new flagship upgraded high-pressure fuel pump for the BMW B58 motor aimed at fueling extreme high performance builds. The pump features about 20% more flow over our existing industry leading 200 bar pump, the FX200. The pump is completely E85 compatible and fully plug and play with no cutting or splicing of any kind required. The added flow will let you run much higher ethanol concentrations and also allow fueling for bigger turbos.

 

Are tune changes required?

The upgraded pump does require calibration changes. It is important to apply these changes prior to starting the car with pump installed to avoid any possible damage and void of warranty. 

Spool Performance can provide calibration details to your existing tuner and/or help you connect with established tuners who are experienced with these pumps. Custom tuning is required to get maximum output out of the upgraded pump setup for your specific vehicle setup and ambient conditions. Spool Performance is a hardware manufacturer and does not provide custom tunes, but can assist with questions your tuner may have.


Low Pressure Fuel Pump Upgrade:

Proper low pressure fueling is extremely important for proper functioning and durability of the high pressure pumps and injectors in a DI system. Inadequate low pressure fueling can cause damage to the pump piston and bore as they are lubricated by controlled leakage of fuel. Resulting damage from low pressure starvation is detectable and would be cause for voided warranties. Please make sure you plan out your fuel system build with proper low pressure upgrades when necessary.
