650S | ID1300-XDS | INJECTOR DYNAMICS | 1300.34.14.14.8

The nominal flow rate is 1335 cc/min (127 lb/hr) at 43.5 psi. This high-flow injector supports E85 setups for McLaren 650S engines, capable of handling approximately 600–750+ WHP for naturally aspirated or lightly modified builds, and 750–900+ WHP for fully tuned forced-induction applications.

This injector features a 34mm short-body length (O-ring to O-ring) with a 14mm lower O-ring and standard upper O-ring. It is a direct-fit solution for the 650S when used with the factory fuel rail and proper Injector Dynamics tuning adapters.

The injector uses the USCAR (EV6/EV14) connector. Depending on the build, a USCAR to McLaren Plug-and-Play (PNP) adapter from Injector Dynamics (or a custom harness) is typically required to interface with the factory fuel system.

Injector Dynamics provides fully validated characterization data including Dead Time (Latency) tables across battery voltages and Flow vs. Pressure tables. This data is essential for the ECU to correctly fuel the 650S engine and maintain precise air-fuel ratios at all operating conditions.

The injector utilizes Dual Slope Matching technology to ensure superior linearity and accurate fuel metering at minimal pulse widths. This guarantees smooth idle and stable low-load operation, eliminating the erratic behavior often seen with generic high-flow injectors.
