Subaru Fluidampr Front Crank Pulley BRZ

Fluidampr front crank pulley for EJ engines.

Performance upgrades increase the naturally occurring, harmful torsional vibrations of the crankshaft. A Fluidampr viscous damper reduces wear on the main bearings and timing gear, gives more accurate valvetrain operation and lowers the risk of crank failure.

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

It protects against turbo and NOS power surges. Components are precision machined and computer balanced. It never needs to be tuned or rebuilt.
