FAST - FST30377-8 - Precision-Flow LS7 Style Fuel Injectors, 35 lb/hr, Set of 8

These new injectors deliver the outstanding idle quality, unparalleled flow consistency, and durability essential for high-performance EFI applications. Engineered for excellent response and fuel atomization, FAST Precision-Flow fuel injectors are manufactured and 100% flow-tested to maintain the industry's tightest tolerances. With flow rates from 30 to 245 lb/hr, these will meet the fuel demands of high-horsepower engines and are compatible with all fuels. These injectors undergo a multi-point dynamic flow test that holds them to within +/- 2% of the stated flow rate across a set of 8 injectors. Testing at multiple pulse widths, rather than just at static flow, ensures consistent cylinder-to-cylinder fuel delivery across the entire engine operating range, not just at maximum capacity. The result is a smoother operating engine that is easier to tune and maintain a consistent cylinder-to-cylinder air/fuel ratio. Available as single injectors or in sets of 8, these FAST Precision-Flow fuel injectors will be the final piece of your fuel delivery system in any EFI-equipped application. FAST Precision-Flow fuel injectors undergo multi-point, dynamic flow testing during manufacturing to deliver precision performance in all conditions.

• Multi-point Dynamic Flow Testing/Ensures that the injectors deliver the required fuel flow throughout their operating range and not just at max flow
• Excellent Fuel Atomization/Maximizes fuel efficiency for clean, complete combustion
• Flow matched to 2%/Consistent fueling from cylinder to cylinder

FAST Precision-Flow LS7 Style fuel injectors are designed for high-performance electronic fuel injection applications requiring consistent delivery, excellent atomization, and dependable operation. This set includes eight 35 lb/hr fuel injectors engineered to support precise cylinder-to-cylinder fueling across the engine’s operating range.

Each injector undergoes multi-point dynamic flow testing at multiple pulse widths rather than static flow testing alone. The injectors are flow matched within 2% across the set of eight, helping maintain a consistent air/fuel ratio, smoother engine operation, and easier tuning. Excellent fuel atomization supports efficient, clean, and complete combustion, while the injectors’ compatibility with all fuels provides flexibility for EFI fuel-delivery systems.
