Spool FX-350 Stage 3+ Upgraded High Pressure Pump [VR30DDTT]

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

The latest and greatest, supporting up to 350 bar pressure. One of a kind on the market.

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.

Spool 10-micron filter unit

Our included 10-micron filter unit boasts the best filtration available on the VR30 market without any noticeable pressure drop in the low side fuel system. The filter unit helps keep the high-pressure pump and injectors safe by protecting them against debris and is highly recommended.

Spool Ethanol Content Monitor

The spool ECA kit for the VR30 features a digital readout of in-tank ethanol content and fuel temperature. It includes our SPOOL Ethanol content analyzer app on mobile and readouts are delivered via BLE 4.0 low energy technology. BLE4.0 allows you to use your regular Bluetooth devices on your mobile devices while being connected to the SPOOL ECA module. The ECA module also has a 0-5V filtered output for flex-fuel implementation on the VR30 platform. Fuel lines used in the kit are braided steel nylon core fuel lines that are 100% E85 compatible.

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.
