This is a brand new 5.5″ ATI Super Damper Crank Pulley for Honda S2000 F20C F22C Engines.
ATI Performance Products has developed Super Dampers for the new Honda F-series engine for Honda S2000 for both street and racing applications. The street version (Part # 918464) comes with 360° laser-etched timing marks and features a single serpentine belt drive on the outer shell to utilize the factory serpentine belt set-up. All F-series Super Dampers exceed SFI 18.1 Safety Certification and are approved for NHRA & IHRA competition.
Much like many other factory parts in your engine, the crank pulley is a wear-item with a shelf-life. The rubber pieces in the factory damper can deteriorate over time, causing a failure that could result in pistons hitting the valves, and destroying your engine. Also, factory crank pulleys were designed to operate at a certain speed and maximum rpm. When racing an engine, we often rev it higher than it was designed to from the factory, pushing many of the factory parts past their design criteria closer to failure.
For this reason, many sanctioned race classes require an “SFI Approved” crank pulley/damper, and will not even allow factory crank pulleys through inspection..
