Innovators West damper for big-block Chevy

Innovators West sponsors damper contingency category for the 2013 AMSOIL Engine Masters Challenge.

Building a high-performance racing engine is a huge investment in both precision hardware and craftsmanship. And while it’s easy to assume that an internally balanced rotating assembly might not care about a damper on the front of the crank, it is. Irrespective of how good an internal balance job is, there are incredible forces of acceleration and deceleration that occur in just a single crankshaft rotation as the individual cylinders compress and expand with explosive force. This sets up resonant vibrations within the crankshaft and it’s important to dampen these forces reliably over a wide range of rpm and load conditions. If not, mechanical carnage will occur. Low-cost dampers just don’t have the ability to cover the wide range of operating conditions experienced by performance engines over the long haul. The experts at Innovators West, however, have made it their mission to provide the highest quality of crankshaft dampers for the AMSOIL Engine Masters Challenge; their SFI-certified dampers (spec 18.1) have been the go-to choice for top engine builders for over 25 years. Inside every Innovators West damper is a free-floating wet-friction clutch pack assembly that uses spring-loaded inertia rings to dampen crankshaft harmonics over a wide rpm range. The rings work in conjunction with clutches to provide outstanding dampening action. That action does generate some heat, and Innovators West uses a small amount of fluid inside that acts as a lubricant and as a heat sink.
