Lightweight Adjustable Camshaft Pulleys – Hard Anodised 7-Series Aluminium – Alfa Romeo Twin Spark – Mandatory for Carburetor Conversions

Description

Technical Product Description:

These high-performance adjustable camshaft pulleys (vernier pulleys) are precision-engineered from aircraft-grade 7-series aluminium and hard anodised for superior surface hardness, wear resistance, and long-term durability.

Designed to provide a significant weight reduction compared to factory pulleys, they allow precise camshaft timing adjustment, improving engine tuning and throttle response. These pulleys are essential for engines with variable valve timing and are mandatory for carburetor conversions where the original timing variator is removed or bypassed.

In carbureted engine setups, where the VVT system is deleted, these pulleys allow correct adjustment of the camshaft phase to optimize engine performance and drivability. They are also required when installing performance camshafts, such as Alfaholics cams, to reset cam timing accurately.

Key Features:

• Manufactured from lightweight, hard-anodised 7-series aerospace-grade aluminium
• Adjustable design enables precise cam timing adjustment
• Significant weight saving compared to factory cam pulleys
• Essential for engines equipped with variable valve timing
• Mandatory for carburetor conversions where the timing variator is eliminated
• Required for performance camshaft setups to reset cam timing correctly
• Ideal for street, track, and motorsport applications
• Direct replacement for original camshaft pulleys in Alfa Romeo Twin Spark engines

Recommended for: High-performance Twin Spark engines, especially those undergoing carburetor conversions or performance camshaft upgrades.

Note: Professional cam timing adjustment is required after installation.
