Frequently Asked Questions

What is the rated flow of the ID1750-XDS for the Caliber SRT-4's 2.4L Turbo engine?

The Injector Dynamics ID1750-XDS delivers approximately 1728 cc/min at 3.0 Bar of pressure. This extreme flow rate is intended for heavily modified, big-turbo Caliber SRT-4s that require high fuel volume for maximum horsepower on E85.

How does the provided injector data from ID help tune the Caliber SRT-4 ECU (AEM, Haltech, etc.)?

Injector Dynamics provides comprehensive latency (dead time) and flow tables. This essential data allows tuners to precisely calibrate the boost, idle, and transient fueling of the Caliber SRT-4, ensuring safety and performance across all conditions.

Are these ID1750-XDS units the correct physical size for the Caliber SRT-4 fuel rail?

Yes, this specific ID1750-XDS set (Part No. 1750.48.14.14.4) features the short body length required for a direct, drop-in fit. It will seat properly in the factory or common aftermarket fuel rails for the 2.4L Caliber SRT-4 engine.

What effect does the superior atomization of the ID1750-XDS have on engine performance and mileage?

Superior atomization creates a finer fuel mist, which leads to more efficient and complete combustion. This results in better power delivery and, surprisingly, can help maintain or even slightly improve part-throttle fuel economy compared to less-precise high-flow injectors.

Is it necessary to upgrade the high-pressure fuel pump when using ID1750-XDS injectors in the Caliber SRT-4?

A significant fuel system upgrade is mandatory. The stock high-pressure pump will not be able to keep up with the volume demand of the 1750cc injectors, especially when using E85, leading to dangerous fuel pressure drops.
