ID1300x - High Flow Performance Injector:

The ID1300x is Injector Dynamics' high-flow injector designed for serious performance applications. At 1340cc/min (approximately 127 lb/hr) at 3 bar, these injectors can support substantial power levels on gasoline or E85. The "x" designation indicates the advanced disc-style internals that provide superior linearity and low-pulse-width performance compared to ball-and-seat designs. This means the injectors perform accurately across the entire duty cycle range, from idle to wide-open throttle, enabling precise fuel control at all operating conditions.

Characterization Data - The Injector Dynamics Advantage:

Every set of Injector Dynamics injectors comes with comprehensive characterization data that describes the injector's precise flow behavior across different pulse widths, fuel pressures, and temperatures. This data is used by your tuner in the ECU to accurately model fuel delivery, enabling a more precise and efficient tune. Without accurate characterization data, tuners must estimate injector behavior, which can result in a less accurate tune. The Injector Dynamics characterization data is recognized and supported by all major ECU platforms including Haltech, Link, AEM, Motec, and others.

E85 and Ethanol Compatibility:

The ID1300x injectors are fully compatible with E85 and other ethanol blends. The internal components and seals are resistant to ethanol's corrosive properties, ensuring long service life even with sustained E85 use. E85 requires approximately 30-40% more fuel volume than gasoline due to its lower energy density, making high-flow injectors like the ID1300x essential for E85 builds. The 1340cc flow rate provides ample capacity for high-power E85 applications.

Disc-Style Internals:

The disc-style internals used in the ID1300x provide superior linearity compared to traditional ball-and-seat injectors. Linearity refers to how consistently the injector flows fuel relative to the commanded pulse width. Highly linear injectors are easier to tune and provide more accurate fuel delivery across the operating range. The disc-style design also provides excellent low-pulse-width performance, which is critical for good idle quality and light-load fuel economy with large injectors.

Dimensional Specifications - Verify Before Ordering:

The 48mm body length, 14mm grey top O-ring, and 14mm lower O-ring dimensions must match your fuel rail for proper fitment. These dimensions are commonly associated with LS-series V8 applications and other V8 platforms. Always verify your fuel rail's injector pocket dimensions before ordering. Using injectors with incorrect dimensions can result in fuel leaks or improper seating. If you are unsure of your fuel rail's specifications, consult your engine builder or tuner.

Fuel System Requirements:

Installing 1340cc injectors typically requires a fuel system capable of supplying adequate fuel volume and pressure. At high duty cycles, 8x 1340cc injectors can demand significant fuel flow. Ensure your fuel pump, fuel lines, and fuel pressure regulator are capable of supporting the injectors' maximum flow requirements. Your tuner can advise on fuel system requirements based on your target power level and fuel type.
