Injector Dynamics ID1750-XDS Fuel Injectors | Single Injector | 48mm, 11mm Adapter Top, 14mm Lower O-Ring (1750.48.11.14)

Duty cycle pegged at 95 percent is not a tune, it is a warning.

A factory fuel system that was sized for stock power runs out of injector long before a built engine runs out of airflow. The ID1750-XDS answers that with 1728cc/min of flow at 3.0 bar, compatibility with methanol, ethanol, and all known hydrocarbon fuels, delivered as a single injector in the 48mm body, 11mm adapter top, 14mm lower o-ring configuration. It is backed by full characterization data, so your ECU gets real numbers, not estimates. It is the boring, repeatable fueling every serious build needs.

What You'll Feel

• Fuel trims that stay put season to season instead of drifting with the weather
• Crisp part-throttle response instead of the surge and stumble big injectors are known for
• Faster dyno sessions, because accurate injector data means less time chasing fuel trims
• Headroom to grow the build without touching the fuel system again
• Stock-like idle and clean cold starts, even at this injector size

Features

• Nominal flow rate: 1728cc/min at 3.0 bar (43.5 psi), measured with E10 emissions certification fuel at 49 degrees C (120 degrees F)
• Maximum differential fuel pressure: 7.0 bar (101.5 psi)
• Compatible with methanol, ethanol, MTBE, nitromethane, and all known hydrocarbon fuels
• Corrosion resistant construction for long service life on alcohol fuels
• USCAR electrical connector
• Configuration: 48mm body, 11mm adapter top, 14mm lower o-ring
• Sold individually, so you can replace one injector or build a set for an uncommon cylinder count

The Details

The ID1750-XDS is the successor to the ID1700x. It adds a higher dynamic flow rate with no increase in minimum fuel mass, better cylinder-to-cylinder balance at low pulse widths, and improved pressure sensitivity, while keeping the "compatible with everything but dirt" corrosion resistance the 1700 was known for. It sits between the 1300 and 2600 in the XDS lineup, sized for serious ethanol and methanol builds that have outgrown the 1300 class. Injector Dynamics publishes full characterization data, including slope, offset (dead time) versus voltage and pressure, and short pulse width behavior, so your tuner can load real numbers instead of chasing fuel trims across the map. Accurate dead times are what make large injectors behave at idle and cruise, and they are the reason these tune quickly and stay tuned. This configuration uses machined top adapters (already fitted) to suit the rail height listed above. If your harness does not have USCAR plugs, plug and play connector adapters are available separately, no cutting or soldering required.
