10mm Stroker CP3 Pump

The Exergy Performance E04 10206 10mm Stroker CP3 Pump is engineered for 2004.5-2005 GM 6.6L Duramax LLY engines, providing a robust solution for those seeking increased fuel capacity beyond the limits of their factory pump. This upgraded CP3 pump offers a reliable path to higher power output, capable of supporting applications up to 800+ HP, while avoiding the potential failure points and complexities associated with multi-pump controllers, custom belts, or secondary pumps. Pioneered through thousands of hours of dedicated research and development, Exergy Performance ensures the reliability of their modified CP3 pumps. Each pump series underwent rigorous durability testing on a bench, simulating extreme conditions with operation at 4500 RPM and pressures exceeding field expectations for 40 hours, followed by thorough inspection for wear. In production, every pump is individually tested across its entire operating range, up to 4500 RPM and 29,000 psi, guaranteeing 100% proper function before installation. This pump is designed as an LBZ-based unit with an LLY fuel pressure regulator for easier tuning on LLY engines. It serves as a direct replacement for Bosch part numbers 0 445 020 030 and 0 986 437 308, as well as GM part number 97303762, and comes with no core charge. To achieve maximum performance, a lift pump capable of delivering 150 GPH at 8-10 psi is required. Additionally, revising the engine tune is recommended for optimal performance at high RPMs.
