Fluidampr Performance dampers offer the best protection against torsional vibrations. Performance tuned or stock, your engine will run more efficiently with a viscous Fluidampr installed. Torsional Vibrations or harmonics can destroy crankshafts and bearings. These vibrations rob horsepower and torque from an engine.
Stock dampers utilize rubber or elastomer to control torsional vibrations. The rubber material not only breaks down over time, but limits the capabilities of the damper. Fluidampr uses a viscous silicone fluid, internal inertia ring and a laser sealed housing. Their precision machined assembly is the most effective way to control torsional twisting at any RPM. Fluidampr has tested on both stock and performance tuned engines. Dyno tests have shown consistent increases in horsepower and torque in the three major engine manufacturers.
Dampers that utilize rubber or elastomeric rings to damper vibrations are know as tuned or frequency sensitive and are designed to function throughout only a narrow predetermined vibration frequency bandwidth. When performance enhancements are made to a stock engine to increase horsepower and torque, whether for commercial, pleasure or competition, the increase in performance overworks the stock rubber damper because of its inherent inability to self tune to the subsequent increased harmonic vibrations.
Rubber dampers are prone to deterioration. Exposure to the heat, oils and solvents can cause the rubber damper ring to crack and/or change durometer. These changes reduce the effectiveness of the damper and over time will cause damper failure and damage to costly engine components.
Each time the air/fuel mixture inside a cylinder is ignited, the combustion event creates a torque spike that is applied to the crankshaft through the pistons and rods. 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/rebound action is known as torsional vibration. When these torque spikes get into phase with the natural frequency of the crankshaft assembly in the engine, critical torsional harmonic vibrations occur that are destructive to the bearings and crankshaft.
