9Y0/9Y3 Porsche Cayenne Turbo FX-350 Upgraded High Pressure Fuel Pump System

Description

Spool Performance FX-350 High-Pressure Fuel Pump Upgrade for Porsche Cayenne Turbo (9Y0/9Y3) with EA825 4.0L V8 What is the FX-350? The FX-350 is an upgraded mechanical high-pressure fuel pump. The pump features a bigger bore size than stock that translates into roughly 90% 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. The pumps are also capable of running higher than stock pressures up to 350bar which increases fuel injector output and also reduced injection time. The Spool Performance FX-350 sets a new benchmark in fuel system engineering, providing superior pressure and atomization for drivers seeking maximum performance from their Porsche Cayenne Turbo. Why Upgrade? The stock high-pressure fuel pump in your Porsche Cayenne Turbo can become a bottleneck when tuning for higher performance. The FX-350 offers 90% more fuel flow, allowing you to safely increase horsepower, run larger turbos, and use higher ethanol blends, making it a critical upgrade for serious performance enthusiasts. Enhanced Pressure The FX-350 is engineered to deliver fuel at an impressive 35Mpa, a significant increase over the FX-200’s 25Mpa. By utilizing the physics principle Q=PxA (flow rate = pressure x nozzle area), the FX-350 increases fuel flow by 40%, ensuring your Porsche Cayenne Turbo receives the necessary fuel for optimal combustion, even under 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 top-tier filtration for your Porsche Cayenne Turbo, protecting the high-pressure pump and injectors from debris without causing pressure drops in the low-pressure fuel system. Spool Ethanol Content Monitor The Spool ECA kit provides real-time data on ethanol content and fuel temperature, accessible via a mobile app. Using BLE 4.0 technology, it wirelessly connects to your smartphone while remaining compatible with other Bluetooth devices. The 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. We provide detailed calibration information for your tuner, and we can recommend experienced tuners familiar with this upgrade. Custom tuning is necessary to fully optimize the FX-350 for your Porsche Cayenne Turbo'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.
