The damper was designed with an adapter plate that accepts the interchangeable crank pulleys available from Metco Motorsports. Metco Motorsports also offers a smaller diameter idler pulley that will allow for even bigger crank pulley sizes for increased boost.

Innovators West harmonic balancers are a great investment for your street or race vehicle. These dampers feature lightweight billet aluminum covers equipped with free-floating wet friction clutch pack assemblies that utilize 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, as well as dissipates heat to the outer body.

LT4 Applications:

Pulley rings as large as 10.0" can be used without changing or relocating idler pulleys on the blower drive. The 8.60", 9.10", 9.55" and 10.0" pulley rings can be used on the Camaro LT4 applications using the appropriate Innovators West balancer, part number - 8410. The 10.50" ring will require minimal modification for clearance of factory components, this ring would be intended for highly modified or serious race applications.

LSA Supercharger Belt Lengths:

• +3 lbs 9.10" Crank pulley ring and stock idler pulley: 84.7" belt
• +3 lbs 9.55" Crank pulley ring and stock idler pulley: 85.3" belt
• +5.5 lbs 10.00" Crank pulley ring and stock idler pulley: 87.125" belt

Estimated Boost Increase (boost levels can vary with build applications):

• +2 lbs with 8.60"
• +3 lbs with 9.10"
• +4.5 lbs with 9.55"
• +5.5 lbs with 10.00"
• +6.5 lbs with 10.50"

Note: Requires Metco supercharger rings. The original crank pulley in LT4 applications is approximately 8.0" in diameter. A pulley ring in this size is not available to fit the Innovators West balancer assembly. Estimated boost increase levels can vary with build applications.
