Spool FX-180 upgraded high pressure pump kit BMW B58
***NOT COMPATIBLE WITH B58TU ENGINE
What is the FX-180?
The FX-180 is an upgraded high-pressure fuel pump for the BMW B58 motor. The pump features a bigger bore size than stock that translates into roughly 80% more flow when compared to stock. 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.
Flow Rates based on B58 stock CAM lift:
Stock B58 Pump – 0.954 cc per rev
FX-180 – 1.7 cc per rev
Why do you need it?
The stock HPFP on B58 motor is severely limited in capacity when trying to tune and raise the output of the motor. The FX-180 adds 80% more flow to the equation, raising the fueling limits on the platform and helping you run bigger turbos and/or higher ethanol concentration blends.
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
