A Little Bit About the Injector Dynamics Technology
Simply stated, a fuel injector is a dynamic device. It does not operate in a wide open or "static" condition. To learn anything of value about a fuel injector, it must be tested dynamically.
It must also be tested in an environment that simulates real world conditions as closely as possible. This means testing with temperature controlled gasoline, methanol, E85 or whatever fluid will actually be used on the running engine.
This type of testing is referred to as dynamic characterization, and was recently introduced to the racing industry by Yawpower in collaboration with Motec USA.
Injector Dynamics fuel injectors are the result of batch testing large quantities of specially modified fuel injectors, and then carefully matching them into sets based on their dynamic flow across the pulsewidth range. The result is vastly superior cylinder to cylinder consistency, even at very low pulsewidths.
In addition to receiving tightly matched injectors, you will be provided with dead time compensation values across the entire pressure and voltage range of the injector. This data will insure that the compensations in your ECU work properly, and your air fuel ratios will remain consistent as atmospheric or voltage conditions change.
Exists for all those applications where the ID1000 is just a little bit too big. The ID725 will maintain strict linearity at flow rates that will satisfy idle and cruise requirements for 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. With pressure capability in excess of 8 bar this injector has found a home in many different applications.
The first offering from Injector Dynamics, and was also the first injector to deliver a number of innovative features to the performance aftermarket. This series of innovations and "firsts" have made it the most popular injector on the market today. The ID1000 was the first injector offered with full dynamic characterization providing tuners with the data they needed to do their job properly. The ID1000 was the first injector to be offered in dead time matched sets. The ID1000 was the first high impedance high flow injector available providing stock idle and drivability on engines as small as 325cc per cylinder. The ID1000 was the first injector offered with the now famous "Top Hat Adapter" making it plug and play in nearly any application. With a maximum pressure capability of 7 bar and excellent low pulse width extension, this is a versatile injector that will be at home in many different applications. From high power high boost daily drivers, to NHRA Pro Stock Motorcycles and record setting turbo road race sedans, the ID1000 set the standard and marked the beginning of a new era in fuel injector performance.
ID2000 has set the standard for linearity and control in a large injector. Flowing in excess of 2000cc/min at 3 bar, the ID2000 will also provide a smooth stoichiometric idle on small bore engines running E85, and it will do all this while maintaining strict linearity up to 95% duty cycle at 9000rpm. With a pressure capability of 9 bar this injector can flow as much as 3700cc/min with excellent low pulsewidth linearity, and has the broadest operating range of any injector on the market.
