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.

Application Notes

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

About Electronic Fuel Injection Throttle Kits

Porsche Electronic Fuel Injection Throttle Kits - Precision Airflow & Throttle Control

Electronic Fuel Injection (EFI) Throttle Kits upgrade the engine’s air delivery system, providing precise throttle control, improved airflow, and enhanced engine response. Designed for performance builds, engine conversions, and modernised classic Porsche applications, these kits replace restrictive or outdated throttle systems with advanced electronic throttle bodies and control hardware.

Available from Design911, Porsche EFI throttle kits are engineered to deliver smoother power delivery, sharper throttle response, and improved drivability—especially in tuned, high-performance, or track-focused engines.

What Do Electronic Fuel Injection Throttle Kits Do?

EFI throttle kits regulate the volume of air entering the engine with high precision, directly influencing power and response.

Core Functions:

  • Control engine airflow electronically and accurately.
  • Improve throttle response and drivability.
  • Support higher airflow demands in tuned engines.
  • Enable precise fuel and ignition mapping.
  • Enhance overall engine efficiency and performance.

Accurate throttle control is essential for modern performance engine management.

Why Do Standard Throttle Systems Fail?

Factory or older throttle systems can become limiting or unreliable over time, particularly in modified engines. Common issues include:

  • Mechanical throttle wear or cable stretch.
  • Inconsistent airflow from ageing throttle bodies.
  • Restrictive designs limiting high-RPM performance.
  • Poor compatibility with modern ECU tuning.
  • Inadequate response for high-performance applications.

These limitations can result in sluggish response, uneven power delivery, and reduced tuning potential.

Why Upgrade to an EFI Throttle Kit?

EFI throttle kits are designed to support modern engine management and higher performance demands.

Upgrade Benefits:

  • Sharper, more consistent throttle response.
  • Increased airflow capacity for power upgrades.
  • Improved compatibility with aftermarket ECUs.
  • Enhanced drivability for road and track use.
  • Ideal for engine builds, conversions, and restorations.

Upgrading to an EFI throttle kit unlocks precise control and maximises engine tuning potential.

Highlights

  • Porsche electronic fuel injection throttle kits
  • Precision airflow and throttle control upgrades
  • Designed for tuned and performance engines
  • Improved response, drivability, and power delivery
  • Compatible with modern ECU management systems
