ID1700-XDS, for 79-84 RX-7. 14mm (purple) adapters. -204 / 14mm lower o-rings. Set of 2.
The ID1700-XDS was designed to fill the gap between the ID1300-XDS and the ID2600-XDS, and like both, it features corrosion resistant internals making it compatible with all known automotive fuels.
A unique magnetic circuit, resulting from a lengthy development program, makes the ID1700-XDS immune to voltage and pressure sensitivity problems that plague other high impedance high flow injectors. The ID1700-XDS excels at high pressures typical of current automotive systems, and will perform flawlessly in these applications.
The ID1700-XDS was designed to be an all fuel compatible injector, capable of very high flow rates. As such, it will most often be used to deliver E85 to boosted engines, or occasionally, gasoline in extreme high horsepower applications. Neither of these applications requires extended linearity at low flow rates, and so this was given a proportionately lower priority during the design process.
The ID1700-XDS will deliver flawless stoichiometric idle and cruise mixtures on E85, but like the ID2600-XDS, should not be expected to do so on gasoline.
If you need flawless drivability on gasoline, the ID1300-XDS will provide this, and is capable of approximately 150hp per injector on E85.
Nominal Flow Rate – 1725cc/min @ 3.0 Bar (43.5 psi) Using Iso-Octane at 52 Degrees C (125 Degrees F)
Maximum Differential Fuel Pressure – 7.0 Bar (101.5 psi)
Fuel Compatibility – Compatible with Methanol/Ethanol/All Known Hydrocarbon Fuels.
Electrical Connector – USCAR
What is Dual Slope Matching?
Dual Slope Matching is a method of matching injectors that provides the best possible cylinder to cylinder fueling across the entire operating range.
Traditionally, injectors were matched based on static flow rate alone, which resulted in large deviations at low pulse widths.
Injector Dynamics introduced Slope Intercept Matching over a decade ago, which provided even cylinder to cylinder fueling across the linear operating range of the injector.
With the progression of turbo technology, and increased use of alcohol fuels, greater demands are placed on fuel injectors, and they are often required to deliver fuel well outside of their linear operating range.
The concept of Dual Slope Matching extends the injector matching into the lower non linear operating range. Dual Slope Matching was conceived by Aaron Looft of Injector Dynamics, who was inspired by the dual slope injector characterization model used by Ford.
