Fuel Injector Clinic 1650cc High-Z Injector Set (ish01-1650h) - Holley GM and Ford
Give your Holley-equipped GM or Ford performance build the fuel capacity to support serious horsepower with the Fuel Injector Clinic 1650cc High-Z injector set. This matched set of eight injectors flows 1650cc/min, or 160 lbs/hr, at 43.5 PSI fuel pressure and 1900cc/min, or 180 lbs/hr, at OE 58 PSI fuel pressure. That massive fuel capacity is paired with excellent linearity and short pulse width repeatability, giving your tuner the injector control needed to build a powerful combination without overlooking idle quality, part-throttle response, and drivability.
The ish01-1650h set is precisely flow matched to within 1 percent, with each injector individually numbered and its results documented on the detailed flow sheet included with the set. Fuel Injector Clinic flow tests and rates its high-performance injectors at 43.5 PSI / 3 Bar and 90 degrees F fuel temperature using CF-16B calibration fluid. Current FIC configurations include PGTJETR8Q solder-in pigtails as well as available EV1 and EV6 direct-connection configurations and a Multec II connector option requiring the appropriate adapter.

1650cc High-Z Fueling for Serious Holley Builds
The ish01-1650h is designed for Holley-equipped GM and Ford combinations where substantial fuel demand makes injector capacity critical. At OE 58 PSI fuel pressure, each injector delivers 1900cc/min, or 180 lbs/hr, giving high-output combinations the fuel capacity needed to support aggressive performance goals. Just as importantly, FIC combines that high flow rate with the injector control required for a properly calibrated engine across a broad operating range.
Precisely Flow Matched to Within 1 Percent
At this level of fuel delivery, consistency between injectors matters just as much as maximum flow. Fuel Injector Clinic precisely flow matches each ish01-1650h set to within 1 percent. Every injector is individually numbered, and its results are documented on the detailed flow sheet supplied with the set. This provides valuable injector-specific information while helping maintain consistent fuel delivery across all eight cylinders.
High Flow Without Ignoring Low-Speed Control
A 1650cc injector still has to accurately meter small quantities of fuel when the engine is idling or operating at light throttle. Fuel Injector Clinic combines the ish01-1650h's substantial flow capacity with excellent linearity, superior short pulse width control, and tight manufacturing tolerances. That predictable response makes accurate calibration easier and helps preserve the drivability expected from a properly tuned performance combination.
Multiple Connector Configurations
Fuel Injector Clinic currently offers the ish01-1650h with multiple connector configurations to accommodate different Holley GM and Ford installations. Options include PGTJETR8Q solder-in pigtails, EV1 direct connection, EV6 direct connection, and a Multec II connector configuration requiring the appropriate adapter. Because connector requirements vary by installation, verify your fuel-system and harness configuration before ordering.
Fuel Injector Clinic chooses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. This approach eliminates the added uncertainty associated with previously used injector cores while providing the performance injector technology required for demanding applications.
Fitment
- Holley GM applications
- Holley Ford applications
Fitment Note: This is a Holley GM and Ford application injector set rather than a vehicle-specific injector package. Compatibility depends on the specific Holley intake, fuel rail, injector connector, and fuel-system configuration being used. Contact Beefcake Racing before ordering if you need assistance confirming the correct configuration for your setup.
