Audi C8 RS7 Sportback FX-350 Upgraded High Pressure Fuel Pump System

Description

Spool Performance FX-350 High-Pressure Fuel Pump Upgrade for Audi RS7 (C8) with EA825 Engine What is the FX-350? The FX-350 is an upgraded mechanical high-pressure fuel pump designed to significantly enhance the performance of your Audi RS7 (C8). With a larger bore size than the stock pump, it delivers approximately 90% more fuel flow, making it perfect for tuning and performance upgrades. Fully E85 compatible and plug-and-play, the FX-350 requires no cutting or splicing for installation. This added fuel flow allows you to run higher ethanol concentrations and fuel larger turbos, providing the flexibility needed for serious performance enhancements. Additionally, the FX-350 can operate at pressures up to 350 bar, improving injector output and reducing injection times for optimized performance. The Spool Performance FX-350 sets a new benchmark in fuel system engineering, delivering superior pressure and atomization for those looking to extract the maximum potential from their Audi RS7. Why Upgrade? The stock high-pressure fuel pump in your Audi RS7 can become a limiting factor when tuning for higher power. The FX-350 offers 90% more fuel flow, allowing you to safely boost horsepower, run larger turbos, and utilize higher ethanol blends. This upgrade is essential for performance enthusiasts aiming to unlock the full potential of their RS7. Enhanced Pressure The FX-350 is engineered to deliver fuel at an impressive 35Mpa, a substantial improvement over the FX-200’s 25Mpa. Utilizing the principle Q=PxA (flow rate = pressure x nozzle area), the FX-350 increases fuel flow by 40%, ensuring your Audi RS7 gets the fuel it needs for optimal combustion, even in extreme performance conditions. What’s Included in the Kit? • 2 x FX-350 upgraded high-pressure fuel pumps • 1 x Ethanol Content Monitor kit (optional), with mobile app • 1 x Bosch spec 10-micron high-flow Fuel Filter • Upgraded fuel lines and installation hardware • Spool 10-micron filter unit The Spool 10-micron filter ensures optimal filtration for your Audi RS7, protecting the high-pressure pump and injectors from contaminants without causing pressure drops in the low-pressure fuel system. Spool Ethanol Content Monitor The Spool ECA kit provides a real-time readout of ethanol content and fuel temperature via a mobile app. Using BLE 4.0 technology, it wirelessly connects to your smartphone while remaining compatible with other Bluetooth devices. The kit’s fuel lines are black nylon-coated, braided steel with a PTFE core, ensuring full E85 compatibility. Are Tune Changes Required? Yes, the FX-350 requires calibration adjustments to prevent damage. Calibration details are provided for your tuner, and we can recommend experienced tuners familiar with the FX-350 upgrade. Custom tuning is essential to fully optimize the FX-350 for your RS7’s specific setup and driving conditions. Low-Pressure Fuel Pump Upgrade To protect your high-pressure pump and injectors, ensuring proper low-pressure fueling is critical. Insufficient low-pressure fueling can damage the pump and void warranties. Make sure your fuel system upgrades include low-pressure pump improvements when necessary. We recommend the torquebyte controller to increase your factory low pressure pump's output by 60% to make sure the hpfp is always receiving sufficient low side flow.
