Fluidampr® – CT Gold
Fluidampr out Guns the Competition
“Viscous style dampers, like Fluidampr, are commonly used in commercial, industrial, aerospace and defense applications for their broad frequency coverage and superior durability,” says Fluidampr’s Brian LeBarron. “Inside a sealed housing is a free rotating inertia ring encased in a thin layer of specified viscous fluid. Crankshaft rpm and vibration causes the outer housing and inner inertia ring to move in and out of phase with each other, and the resulting shearing action through the fluid transforms the vibration to heat and dissipates it through the outer housing surface. Since the inertia ring and housing are not bonded and limited in their reaction and movement like an elastomer design, a viscous damper can become more effective with greater vibration amplitudes.”
CT Gold Developed for superior control of crankshaft torsional vibration experienced during circle track and drag racing applications. Features a precision machined and computer balanced housing and internal inertia ring, plus patent pending centering technology. The inertia ring shears through proprietary silicone allowing it to continuously self-tune and dampen torsional vibration in real time across a broad, rapidly changing frequency and rpm range. Race engine may be balanced with CT Gold damper installed. Features precision machined and computer balanced components. Never needs to be tuned or rebuilt between races. SFI Approved. Made 100% in the U.S.A. ISO Certified.
