Spool Performance FX-350 High-Pressure Fuel Pump Upgrade for Porsche 911 Turbo (992) with 3.7L Twin-Turbo Flat-Six
What is the FX-350?
The FX-350 is an upgraded mechanical high-pressure fuel pump designed to significantly enhance the performance of your Porsche 911 Turbo (992) with the 3.7L twin-turbo flat-six engine. This pump features a larger bore size than the stock unit, providing approximately 90% more fuel flow. The FX-350 is fully E85 compatible and is a plug-and-play solution that requires no cutting or splicing. The additional fuel flow allows for higher ethanol concentrations and supports bigger turbo setups, making it ideal for performance upgrades. Additionally, the FX-350 can operate at pressures up to 350 bar, increasing injector output and shortening injection times.
The Spool Performance FX-350 sets a new standard in fuel system technology, providing exceptional pressure and atomization for drivers seeking maximum performance from their Porsche 911 Turbo.
Why Upgrade?
The stock high-pressure fuel pump in your Porsche 911 Turbo can restrict performance when tuning for higher outputs. The FX-350 delivers 90% more fuel flow, enabling you to safely increase horsepower, accommodate larger turbos, and run higher ethanol blends. This upgrade is essential for serious performance enthusiasts looking to unlock their 911 Turbo's full potential.
Enhanced Pressure
The FX-350 is engineered to deliver fuel at an impressive 35Mpa, a significant improvement over the FX-200’s 25Mpa. By utilizing the principle Q=PxA (flow rate = pressure x nozzle area), the FX-350 increases fuel flow by 40%, ensuring your Porsche 911 Turbo receives the necessary fuel for optimal combustion 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 superior filtration, protecting your Porsche 911 Turbo's 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 ethanol content and fuel temperature monitoring 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 avoid damage. Detailed calibration information is 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 Porsche 911 Turbo's specific setup and driving preferences.
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. Please visit
