ATI Performance Products ATI916187WPP-B Supercharger Pulley Package Black

The ATI Performance Products ATI916187WPP-B is a supercharger pulley package finished in black, designed for high-performance forced-induction applications. ATI's supercharger pulley packages integrate seamlessly with their Super Damper platform, eliminating the need for a separate crank-mounted blower pulley by incorporating the blower drive directly into the damper assembly.

Key Features:

• Integrated blower drive design — places supercharger belt drive function inside the crankshaft damper assembly for a cleaner, more efficient setup
• External belt drive compatibility — accommodates virtually any type of supercharger belt configuration
• Black finish — durable black oxide or black zinc chromate coating for corrosion resistance and a clean appearance
• SFI 18.1 compliant construction — meets or exceeds SFI 18.1 safety specifications for racing applications
• Laser-engraved 360° timing marks — precision timing reference for accurate ignition tuning
• Dual-keyway hub — provides positive crank indexing and enhanced drive security
• Elastomer damping technology — absorbs and eliminates torsional crankshaft vibrations that can damage rotating assembly components
• Optimized pulley offset — keeps the supercharger drive as close to the engine block as possible, minimizing bending moment on the crankshaft snout

ATI Performance Products has been a leader in crankshaft damper and supercharger drive technology for decades, trusted by professional racers and serious enthusiasts alike. This pulley package is engineered for reliability under the extreme demands of supercharged street and race engines.
