SPOOL FX-350 STAGE 3+ UPGRADED HIGH PRESSURE PUMP [VR30DDTT]

Spool Performance FX-350 Stage 3 High-pressure fuel pump upgrade

What is the FX-350?

The FX-350 is an upgraded high-pressure fuel pump. The pump features a bigger bore size than stock which translates into about 400LPH of fuel flow and our innovative high-efficiency flow pathways helps it deliver fuel at upto 350Bar or pressure. This help decrease injection duration times through the same injector compared to the stock delivery pressures. Combined with our IFX-22 injectors, you can flow an additional 40% of fuel through the IFX-22 injectors virtually eliminating any injector limitations on the platform while maintaining the ability to be dynamically controlled for low load stability. The increased atomization aids a more efficient combustion unlocking even more horsepower! 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.

Why do you need it

The stock HPFP on the VR30DDTT Motor is severely limited in capacity when trying to tune and raise the output of the motor. The FX-350 adds about 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. FX350 also lets you run 350 bar of fuel pressure bringing in never before seen combustion efficiency to the platform.
