Calibration Kit - 750 Street Demon

The Demon Carburetion 750 Street Demon Calibration Kit is a precision tuning component set designed to optimize carburetor performance on 750 CFM Street Demon carburetors. This kit contains metering rods, metering jets, calibration springs, and a protective case—everything needed to dial in air-fuel mixture for peak engine response across varying load conditions and RPM ranges.

Metering rods and jets directly control fuel delivery at different throttle positions. By adjusting these components in combination with the supplied springs, tuners can compensate for ambient temperature, altitude, fuel quality, and engine modifications. The included case keeps all components organized and protected during storage and transport. This calibration-specific kit allows for fine-tuning without replacing the entire carburetor assembly, making it an economical choice for street enthusiasts, hot rod builders, and performance tuners who need precise control over mixture curves.

Users of Street Demon carburetors who have experienced hesitation, stumbling on acceleration, or suboptimal fuel economy will benefit from this kit's ability to recalibrate the metering system. Whether following a recent engine rebuild, switching fuel blends, or relocating to a different climate zone, this kit provides the necessary adjustment hardware to restore smooth drivability and efficiency. Ideal for DIY tuners and professional shops working with naturally aspirated small-block applications.

At 0.33 lbs and compact dimensions (3.7 x 1.4 x 7.1 inches), the kit is portable and fits easily in a tool drawer or garage workbench. Part number 1931 ensures compatibility with the 750 CFM Street Demon carburetor lineup.
