The Allstar Performance Multi Siper Head 8 Blade is a precision-engineered supercharger pulley head designed for serious automotive builders and engine tuners seeking reliable power delivery and consistent boost management. Built by Allstar Performance—a trusted name in high-performance engine modification—this multi-blade supercharger pulley head serves as a critical interface between your blower drive system and the engine's output, making it essential for anyone upgrading or maintaining forced-induction platforms.
The 8-blade design optimizes surface contact and load distribution across the belt, reducing slippage and maintaining consistent pulley speed ratios under varying engine loads and boost conditions. The grooves enhance grip between the belt and pulley, critical for minimizing belt walk and heat buildup during sustained high-RPM operation. Constructed to Allstar's precision manufacturing standards, this lightweight component weighs 0.45 lbs, minimizing rotational inertia while maintaining structural rigidity—a balance essential for reliable supercharger operation.
The compact dimensions (4 x 1.15 x 7 inches) allow straightforward integration into most forced-induction engine bay configurations. Whether you're building a street performance engine, preparing for bracket racing, or refining an existing supercharger setup, this component ensures proper belt engagement and efficient power transfer from crankshaft to supercharger. It is ideal for use with Roots, Twin-Screw, and Centrifugal Superchargers, making it a versatile choice for various applications.
