Fluidampr is a premium, viscous-style harmonic balancer designed to protect internal engine components from destructive torsional (twisting) vibrations. It replaces the stock, rubber-based elastomer pulley with a maintenance-free steel housing enclosing a free-floating inertia ring suspended in thick silicone gel.

Key Features and Benefits

Broad RPM Protection: Unlike the stock rubber dampers that are strictly tuned to a single frequency, Fluidampr continuously self-tunes in real time. This makes it ideal for modified, high-revving, or forced-induction engines.

Energy Dissipation: As the crankshaft twists during the combustion cycle, the inner ring and outer housing move out of phase. The shearing action through the silicone fluid converts destructive vibrational energy into harmless heat.

Engine Longevity: By neutralizing harsh harmonics, it reduces wear on main engine bearings, connecting rod bearings, oil pumps and oil pump gears and minimizes gearbox chatter, and reduces the risk of crankshaft failure.

Performance: It helps stabilize valvetrain timing accuracy and often frees up lost low-end torque and horsepower.

Durability: Built from precision CNC-machined steel with no elastomer to dry out or crack, they require no maintenance or rebuilding. Many units are SFI 18.1 certified for safety in racing applications.

Fluidampr Engine Dampers are designed to control destructive vibrations which are transfered thru the crankshaft.

Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations.

Critical harmonic vibrations occur numerous times in a engine's operating range. Stock rubber and elastomer-type dampers are frequency sensitive "tuned absorbers", and work at only one critical frequency. In the case of a stock rubber damper, it is tuned for a factory engine's critical harmonic vibrations. If you change the mass of pistons, rods, or the crankshaft, you change the natural frequency of the crankshaft assembly; therefore, the stock damper is no longer tuned to the new frequency of vibration, and you may be headed for early failure of expensive engine components. Dampers also create heat while they work, and rubber is a poor dissipator of heat. This heat and the exposure to the elements deteriorates rubber, causing it to crack and change durometer, which then leads to inertia ring slippage, damper failure, uncontrolled torsional vibration, and costly engine parts breakage.
