The Ordnance 650 is designed as a max-effort, max-RPM competition fuel pump, delivering an impressive 650 L/H maximum flow at 6,000 RPM. In addition to increased flow at high RPM, they’ve reduced return flow by 50% and lowered the required supply pressure by 30%.
This pump begins as a brand-new Bosch-based CP3, modified by S&S Diesel Motorsport, and receives a durable Cerakote finish to protect against corrosion. It’s assembled with a new flange featuring their gForce block now integrated, which eliminates g-force effects during launch and simplifies the design.
