Give your Whipple-supercharged 2021-2026 Ford F-150 5.0L the fuel capacity needed for serious horsepower with the Fuel Injector Clinic 1650cc High-Z injector set. This matched set of eight injectors is rated at 180 lbs/hr at 58 PSI fuel pressure and 1650cc/min, or 160 lbs/hr, at 43.5 PSI. The is407-1650h combines substantial fuel delivery with excellent linearity and short pulse width repeatability, giving tuners the control needed for responsive idle and part-throttle operation while providing the additional fuel volume demanded as boost, load, and horsepower increase.
Fuel Injector Clinic builds its 1650cc high-impedance injector with stainless alloy valve construction for broad fuel compatibility, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each set is precisely matched using FIC's proprietary Data Match Technology, with every injector individually serial numbered and documented on the supplied Data Match Sheet. FIC flow tests these injectors at 43.5 PSI / 3 Bar and 90 degrees F fuel temperature using CF-16B calibration fluid, and plug-and-play Ford ECU data is available to support accurate calibration.

1650cc Fuel Capacity for High-Horsepower Whipple F-150 Builds
The FIC 1650cc injector is built for Whipple-supercharged F-150 combinations where serious airflow and horsepower require equally serious fuel delivery. Rated at 180 lbs/hr at 58 PSI, the is407-1650h provides substantial fueling capability while maintaining the precise injector behavior needed for accurate calibration. It gives high-output 5.0L combinations additional fueling headroom without sacrificing the low-speed control that matters in a street-driven performance truck.
High Flow with Excellent Street Manners
Large injectors need to perform accurately when the engine is barely demanding fuel as well as when it is under heavy boost. Fuel Injector Clinic's 1650cc injector combines excellent idle performance with superior short pulse width control and linearity. These characteristics help the ECU accurately meter fuel during idle, cruising, and part-throttle operation while retaining the flow capacity required when the Whipple-supercharged 5.0L is under load.
Data Match Technology for Precise Tuning
Consistent fuel delivery across all eight cylinders becomes increasingly important as boost and horsepower rise. Fuel Injector Clinic precisely matches each is407-1650h set using proprietary Data Match Technology. Every injector is individually serial numbered, and detailed flow matching and latency information is supplied on the Data Match Sheet. This provides your tuner with accurate injector data for consistent cylinder-to-cylinder fueling and precise calibration throughout the operating range.
Broad Fuel Compatibility
Stainless alloy valve construction gives the FIC 1650cc injector the versatility needed for a wide range of performance fuels. Fuel Injector Clinic specifies compatibility with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. This broad compatibility makes the is407-1650h a flexible choice for high-performance F-150 builds where fuel choice may change as the combination and power goals evolve.
Drop-In Electrical Connection
The is407-1650h uses a factory-style electrical connector for straightforward installation with no injector plug conversion required. Fuel Injector Clinic also supplies the O-rings required for the applicable factory configuration. Combined with available Ford ECU data, the application-ready design helps simplify both installation and calibration when upgrading the fuel system on a Whipple-supercharged F-150.
