PERFORMANCE SILICONE DAMPERS

FOR GAS AND DIESEL ENGINES

 

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. Fluidamprs are designed to control those destructive vibrations.

Rubber VS Silicone Fluid
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.

Fluidampr Performance Diesel dampers offer the best protection against torsional vibrations. Performance tuned or stock, your diesel 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 your engine. Stock dampers utilize rubber or elastomer to control torsional vibrations. The rubbery material not only breaks down over time, but also limits the capabilities of the damper. Fluidampr uses a viscous silicone fluid, internal inertia ring and a laser sealed housing. Our precision machined assembly is the most efective way to control torsional twisting.
Fluidampr has tested on both stock and performance tuned diesel pick-ups. Dyno tests have shown consistent increases in horsepower and torque in the three major manufacturers.
