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.
