Fluidampr Sport Compact Viscous Damper – Subaru EJ20/25

Fluidampr® Sport Compact Viscous Damper – Subaru EJ Engine (Part #531101)

Application: Subaru EJ / Saab engines  |  Part #: 531101

Performance upgrades increase the naturally occurring characteristics of harmful crankshaft torsional vibrations. By installing a Fluidampr viscous damper you will reduce wear on the main bearings and timing gear, achieve more accurate valvetrain operation, and lower the risk of crank failure.

Unlike rubber-based dampers, Fluidampr automatically adapts to your modifications, then continuously self-tunes in real time to optimum damping at both peak levels and across a broad, changing frequency range. As the engine revs up, torsional vibration suspends the inertia ring and reduces its weight felt on the crankshaft — measured as rotating weight, this effect helps maintain quick revs while preserving optimum dampening.

A must-have for instant protection against turbo and NOS power surges.
