The ID725's are the smallest injectors provided by Injector Dynamics. Flowing 715cc/min at 3 Bar, and being compatible with all known fuels, they are a good choice for most normal builds. The ID725 exists for those applications where the ID1000 is just a little bit too big, and will maintain strict linearity at flow rates that will satisfy even the smallest engines. This makes the ID725 ideal for emissions compliant OEM applications while offering the high flow rates required for mildly boosted motors.
As you probably already know, Injector Dynamics are all about matching sets of injectors for sale. Not all injectors are equal, and it is simply not possible to keep to the types of tolerances required to get them to all flow precisely the same amount straight from the production line. Up until now most people have had to run multiple stages of injectors to allow high flow rates whilst retaining a good idle / cruise efficiency with small primary injectors. Not any more. Injector Dynamics dynamically test every injector they make. They then group them into sets that have the closest possible characteristics, and sell them like this.
This guarentees that all of your cylinders receive the amount of fuel that you command, resulting in smoother running in ALL situations, from Idle to wide open throttle at high RPM, due to cylinder to cylinder balance of AFR's. They also flow very linearly at low pulsewidths, meaning they are predictable to the ECU, which is what allows them to provide such good idle and part throttle driveability.
