Frequently Asked Questions About the Magnum SRT-8 ID1050-XDS Injectors
What maximum E85 horsepower will the ID1050-XDS set support on a Magnum SRT-8 6.1L Hemi?
The ID1050-XDS flows about 1065 cc/min (roughly 101 lb/hr) at 43.5 psi, giving it enough fuel capacity for 700–800+ wheel horsepower on E85 when used as an 8-injector set on a 6.1L Hemi. Actual supported output depends on boost level, fuel pressure, and engine efficiency. On pump gas, the horsepower range typically increases because of lower fuel volume requirements.
Is the 1050.48.14.14B.8 injector a true drop-in fit for the Magnum SRT-8 fuel rail?
Yes. This injector uses the 48mm short-body design with 14mm O-rings, which matches the factory injector dimensions on the 6.1L Hemi platform. It drops directly into the stock Magnum SRT-8 fuel rail and intake manifold without any spacers, extensions, or modifications.
Will the ID1050-XDS plug directly into the Magnum SRT-8 injector harness?
Yes. This version of the ID1050-XDS uses the USCAR/EV6 connector, which is the same connector used on the Magnum SRT-8’s factory wiring harness. No electrical adapters or rewiring are required for installation.
Where can my tuner find official Injector Dynamics calibration data for the Magnum SRT-8?
Injector Dynamics provides complete characterization data including Dead Time, Offset, Short Pulse Adder, and Flow vs. Pressure tables. These files are available directly from Injector Dynamics and import cleanly into HP Tuners and other Hemi tuning platforms, ensuring proper fueling and stable idle quality.
How does the ID1050-XDS maintain smooth idle and drivability on a high-flow Hemi setup?
The ID1050-XDS uses Injector Dynamics’ advanced Dual Slope Matching, which ensures extremely precise fuel delivery at small pulse widths. This eliminates the poor low-RPM behavior commonly seen with large injectors, allowing the Magnum SRT-8 to retain OEM-like idle stability and crisp part-throttle drivability.
