Fuel Injector Clinic 850cc High-Z Fuel Injector Set (ish03-0850h) - Holley GM Composite Intake
Upgrade your Holley GM composite intake with the precise fuel delivery and tuning control of the Fuel Injector Clinic 850cc High-Z Fuel Injector Set. Part number ish03-0850h includes eight saturated, high-impedance injectors rated at 850cc/min, or 81 lbs/hr, at 43.5 PSI and 94 lbs/hr, or 980cc/min, at the OE 58 PSI fuel pressure. Built with modern injector technology, these injectors deliver excellent linearity and short pulse width repeatability, making them a strong choice for performance combinations that demand increased fuel capacity without giving up the drivability and control needed during idle and part-throttle operation.
Every ish03-0850h set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered, and its results are documented on the supplied Data Match Sheet, providing detailed flow-matching and latency information that gives your tuner accurate data for calibration. FIC flow tests and rates these injectors at 43.5 PSI using CF-16B calibration fluid maintained at 90 degrees F. Plug-and-play GM ECU data is also available from Fuel Injector Clinic to further support accurate setup and tuning.

Fitment
Designed for Holley GM composite intake applications. Fitment is based on the intake and fuel system configuration rather than a specific vehicle year, make, or model. If your combination uses aftermarket fuel rails, a modified intake, or another unusual fuel system configuration, contact Beefcake Racing before ordering to verify proper injector fitment.
FAQs
What is the flow rate of the Fuel Injector Clinic ish03-0850h injector set?
The ish03-0850h injectors are rated at 850cc/min, or 81 lbs/hr, at 43.5 PSI (3 Bar) fuel pressure. At the OE 58 PSI (4 Bar) fuel pressure, they flow 94 lbs/hr, or 980cc/min. Fuel Injector Clinic previously offered this injector under a 770cc rating.
How does Fuel Injector Clinic Data Match Technology help with tuning?
Rather than relying only on a nominal injector flow rating, Fuel Injector Clinic precisely matches the injectors within the set and individually serial numbers them. The supplied Data Match Sheet provides detailed flow-matching and latency information, giving the tuner accurate injector data while superior short pulse width control helps support smooth idle, part-throttle operation, and overall drivability.
Why Buy Fuel Injector Clinic Injectors From Beefcake Racing?
The right injector needs to deliver enough fuel for your performance goals while also matching your intake, fuel system, and calibration requirements. Beefcake Racing can help you determine whether the Fuel Injector Clinic ish03-0850h is the right choice for your Holley GM composite intake combination.
