Lightweight Adjustable Timing Pulley – Alfa Romeo 1600 Nord

Technical Product Description:

This high-performance lightweight timing pulley 125mm is CNC-machined from forged 4320 Ni-Cr-Mo steel, delivering superior strength and wear resistance for critical valvetrain components in high-RPM and competition engines.

Equipped with laser-etched degree markings for precise camshaft timing adjustments, it enables fast, repeatable tuning of cam phasing to optimize power delivery, torque curve, and throttle response.

Compatible with a wide range of Alfa Romeo twin-cam applications, including:

• Nord 1300 and 1600 engines

Key Technical Features:

• Material: 4320 forged alloy steel — heat-treated for surface hardness and fatigue resistance

• Design: Lightweight construction for reduced rotating mass and improved valve train response

• Adjustability: ±10° crank equivalent adjustment range via slotted mounting holes

• Degree scale: Laser-engraved markings with high-contrast finish for accurate visual reference

• Compatibility: Fits standard and aftermarket camshafts on 8V Twin Spark and Nord engines

• Balancing: Dynamically balanced to ensure vibration-free operation at high RPM

Recommended for engine builders, tuners, and racers requiring precise camshaft timing control in naturally aspirated and turbocharged Alfa twin-cam engines.

Note: Available in single and double pulley configurations for intake/exhaust tuning.
