Thumbnail Filmstrip of LLY Duramax Reman Injectors 200% Over S&S Diesel LLY-200SAC-R Images
For LLY Duramax owners from 2004.5–2005 looking to redefine their engine's capabilities, the S&S Diesel LLY-200SAC-R Reman Injector Set is the essential upgrade. Engineered for competition and extreme performance builds, these injectors are the heart of a high-power diesel setup, delivering a significantly increased fuel flow to unlock massive gains in horsepower and torque. This enhanced fuel delivery translates directly into a sharper, more immediate throttle response and an overwhelming improvement in overall engine performance, making them perfect for dedicated racers or those who demand maximum power for towing heavy loads.
The engineering behind the LLY-200SAC-R injectors provides not just increased volume, but highly controllable and consistent fuel delivery. By carefully matching the nozzle flow rate to the injector build specification and employing proprietary honing and flow-matching techniques, S&S Diesel ensures that the immense power generated is also reliable and balanced across the engine's operation. This commitment to precision guarantees that your high-performance Duramax build receives the precise, high-volume fuel it needs to achieve its competitive potential, providing you with a distinct advantage on the track or the confidence to handle the toughest hauling jobs.
The LLY-200SAC-R Injector Set is defined by its cutting-edge design and meticulous quality control:
- Unprecedented Flow Rate: The "200% Over" designation signifies a 200% increase in fuel flow rate compared to a stock (factory) injector, enabling the substantial power output required for extreme performance.
- Precision Fuel Delivery: Features a proprietary design utilizing upgraded internal components and a specialized nozzle honing process to ensure clean, consistent holes for optimal fuel atomization and distribution.
- SAC Nozzle Technology: Incorporates SAC-type nozzles, a specific flow path design that expertly balances performance and emissions control characteristics.
- Maximum Flow Matching Accuracy: Each set undergoes a rigorous flow-matching process to guarantee balanced fueling across all cylinders, reducing stress and maximizing efficiency:
- Nozzles are matched to a tight 1% variance per set.
- Complete injectors are matched to a 3% variance per set.
- This matching is verified using OE standards with Viscor SAE-J967 fluid at 40C and 100 bar pressure.
- Consistent Injection Profile: Alignment of injection profiles (rate shape) across the set, verified at 4 different pressure/energizing points per injector, ensures predictable and repeatable power delivery.
- Optimized for High-Flow: For this flow rate and higher (250% and up), internal body modifications are incorporated to improve the injection rate shape, counteracting the natural delay in open/closing time caused by the increased nozzle flow.
Note: Installation of these injectors requires supporting modifications such as upgraded lift pumps, CP3 pumps, high-flow filtration, turbocharger upgrades, and mandatory custom engine tuning to function correctly and safely. They are primarily intended for off-road/competition use, and users should verify local regulations regarding street legality.
