Description
Unlock the full fueling capability of your Porsche Cayenne Turbo with the Spool Performance FX-350 High-Pressure Fuel Pump Upgrade — engineered to deliver massive fuel flow, increased pressure, and the reliability required for high-performance EA825 builds.
The FX-350 is a complete plug-and-play solution designed for enthusiasts pushing beyond factory limitations. Featuring a larger bore design, this upgraded pump delivers approximately 90% more fuel flow than stock, providing the headroom needed for high boost, larger turbochargers, and ethanol-based tuning.
Capable of operating at pressures up to 350 bar (35 MPa), the FX-350 enhances injector efficiency by increasing output while reducing injection duration — resulting in improved combustion, better throttle response, and consistent power delivery under extreme conditions.
Why Upgrade Your HPFP?
The factory high-pressure fuel pump quickly becomes a restriction when increasing boost, airflow, or ethanol content. The FX-350 eliminates this bottleneck, allowing your engine to safely produce more power without compromising fueling stability.
- Supports higher horsepower builds
- Enables safe use of high ethanol blends (E50–E85)
- Provides fueling for upgraded and hybrid turbo setups
- Prevents lean conditions at high RPM and load
Advanced Fueling Performance
Massive Flow Increase
- ~90% higher fuel flow vs OEM
- Supports aggressive tuning and high boost levels
350 Bar High-Pressure Capability
- Increased injector output
- Shorter injection windows
- Improved atomization and combustion efficiency
E85 & Ethanol Ready
- Fully compatible with high ethanol content fuels
- Stable fueling under increased volume demand
Engineering Advantage
Using the principle of flow = pressure × area (Q = P × A), the FX-350 maximizes both pressure and delivery efficiency. Compared to lower-pressure systems, this results in:
- Faster fuel delivery under load
- Improved combustion stability
- More consistent air-fuel ratios
What’s Included:
- 2 × FX-350 Upgraded High-Pressure Fuel Pumps
- Ethanol Content Monitor Kit (Optional) with Mobile App
- Bosch-spec 10-Micron High-Flow Fuel Filter
- Upgraded Fuel Lines & Installation Hardware
- Spool 10-Micron Filter Unit
Integrated Filtration System
The included 10-micron high-flow filter provides superior protection for your fuel system:
- Prevents contaminants from reaching injectors and pump
- Maintains optimal fuel pressure without restriction
- Fully compatible with E85 and high-performance fuels
Spool Ethanol Content Monitor
Monitor your fuel quality in real time:
- Live ethanol percentage readings
- Fuel temperature monitoring
- Wireless Bluetooth connectivity (BLE 4.0)
- Seamless smartphone app integration
This ensures safe operation when running variable ethanol blends.
Tuning Requirements
Custom tuning is required when installing the FX-350.
- Calibration data provided for tuners
- Ensures safe fuel delivery and engine operation
- Optimizes performance based on your setup
Low-Pressure Fueling Recommendation
To maintain proper system balance and protect your HPFP:
- Upgrade your low-pressure fuel system when necessary
- Prevents starvation and premature wear
- Recommended: Torqbyte controller (up to +60% LPFP output)
Features:
- ~90% increase in fuel flow over stock
- Up to 350 bar (35 MPa) fuel pressure
- Full E85 compatibility
- Plug-and-play installation (no cutting or splicing)
- Supports high horsepower and big turbo builds
- Improved injector efficiency and combustion
- Complete fueling solution with filtration and monitoring
