Thumbnail Filmstrip of 6.7 Cummins Ordnance 650 CP3 w/Gen2 SP3000 Mechanical Supply Pump S&S Diesel 6.7C-CP3-ORD650-SP Images
The S&S Diesel Motorsport Ordnance 650 is a precision-engineered, high-pressure fuel solution designed specifically for the rigorous demands of max-effort competition. Built upon a brand-new Bosch CP3 foundation, this pump is significantly modified to overcome the limitations of standard fueling systems in high-RPM environments. By integrating a patent-pending billet aluminum flange with a gForce block, S&S has effectively eliminated the fuel starvation issues typically caused by extreme longitudinal forces during a hard launch. Furthermore, the entire unit is treated with a specialized Cerakote finish, ensuring that the internal engineering excellence is matched by an exterior capable of resisting harsh corrosive elements found in racing conditions.
- Exceptional Flow Capacity: Engineered to deliver a consistent 650 L/h at 6,000 RPM, with the capability to maintain and increase flow beyond that threshold for high-revving competition engines.
- Integrated Gen2 SP3000: This configuration includes the SP3000 low-pressure supply pump, providing a streamlined, mechanical fueling solution that simplifies plumbing while maximizing reliability.
- Advanced Metering Control: Features a modified Inlet Metering Valve (IMV) optimized for high-speed efficiency, requiring a specific 2,200 mA current to reach full closure.
- Optimized Plumbing Architecture: Utilizes dedicated -6AN hose configurations for both the M12x1.5 feed port on the billet flange and the return port on the forged body to ensure stable pressure dynamics.
- Launch Stability: The integrated gForce block simplifies the overall design while ensuring consistent fuel delivery even as the vehicle experiences extreme acceleration.
Success with the Ordnance 650 requires a departure from standard tuning logic, as this pump does not follow a stock delivery curve. It is imperative for tuners to utilize the unique data sheet provided with each unit to calibrate the IMV curve correctly within the ECU. To ensure the longevity and peak performance of the system, S&S Diesel strongly recommends the use of the Regulated Filter Head (FDS-RFH-ASM) to maintain precise supply pressure. When plumbing the return system, each pump must have a dedicated line routed back to the fuel cell below the fluid level to prevent aeration. For those maintaining the unit, extreme care must be taken to ensure that exactly one ceramic check ball remains in each high-pressure outlet valve port, preserving the mechanical integrity of the 6.7L Cummins fueling system.
