Fluidampr Sport Compact crankshaft dampers are ideal for anyone looking for a replacement damper to the individual looking for a superior harmonic balancer for a modified sport compact engine with increased power and higher engine RPM levels. From stock power to a full-blown competition motor Fluidampr harmonic crankshaft balancers have you covered. A normal stock damper is considered a wear item that needs to be replaced. The OEM dampers were also designed to operate at the stock power level. It is often suggested by the OEM in your service manual and in as little as 30,000 miles. This change interval is a model-specific requirement. Sport compact performance upgrades drastically increase the harmful torsional vibrations produced with every single power stroke of an internal combustion engine. Any engine power upgrade can cause an increase in vibrations. Increased vibration levels generate an additional workload on the stock rubber damper which causes the OEM rubber damper to overheat and fail prematurely. Stock dampers are tuned for maximum effectiveness with a stock rotating assembly when it's spinning at low rpm's. When the pistons, connecting rods, or crankshaft are changed or modified, or normal rpm range is increased, the effectiveness of a stock damper is reduced.
Only a viscous damper from Fluidampr is designed to provide effective control of all engine harmonic vibrations, regardless of the rpm at which they occur and regardless of the crankshaft's natural frequency. The Fluidampr Viscous Sport Compact Dampers provides the maximum level of protection for the crankshaft, main bearings, valve train components along with increased power output. All Fluidampr Sport Compact Dampers are designed as a maintenance-free bolt-on performance upgrade. Fluidampr is effective on both race and street applications.
The installation of any performance parts that increase the engine's power output or torque, such as intake, camshafts, rods, pistons, flywheel, flexplate, fuel pump, injectors, exhaust system or any ECM changes typically will increase in torsional vibration magnitude and frequency. These performance upgrades also increase torsional vibrations above a level the OEM damper was not designed to handle. A stock harmonic balancer typically is only tuned for a 50hz peak variance at a particular power level. In addition to previously mentioned performance upgrades, if you alter any of the engines rotating assembly parameters and it may leave your critical engine components unprotected when torsional vibration is at its peak. Signs that the OEM stock vibration damper is now failing: Bonded rubber on the harmonic balancer is now cracked, bulging or missing rubber between the hub and outer ring. Age and repeating heat cycles have caused the rubber to degrade. The OEM rubber is also sensitive to solvents and cleaning compounds. Subjecting your damper to these chemicals accelerates the degradation of the damper compounds.
Fluidampr dampers utilize a unique viscous fluid which unlike rubber is very thermally stable and able to withstand the test of time and will NEVER wear out in a performance application.
Due to the countless combinations of performance upgrades possible, the simplest and most cost-effective solution for controlling dangerous torsional vibrations is to install a Fluidampr high-performance sport compact viscous damper on your engine. By design, Fluidampr viscous vibration dampers protect your engine from torsional vibrations across a broad range of frequencies, engine RPMs, and power levels. A viscous vibration damper also continuously self-tunes in real-time throughout the RPM range to adapt to your next engine modification. The earlier a Fluidampr performance damper installation takes place, the more you will benefit from its protection, performance, and the ability to ensure long term engine life.
The harmonic balancer job is to control the destructive crankshaft torsional vibrations. These vibrations are produced with each power stroke of the engine during the combustion process. The power cycle of the engine generates a twist and rebound effect upon the engine's crankshaft which causes torsional vibrations or harmonic waves which can be transmitted from the crankshaft to any metal engine or driveline component. The torsional vibrations are the end-to-end twisting or rebound motion exerted on the crankshaft during each power stroke. A torsional harmonic balancer controls these forces and allows for increased valve train and timing efficiency. The other benefits obtained by the installation of a viscous crankshaft damper are a reduction in the wear of critical engine components such as main bearings, oil pump, drive-train, and ultimately the crankshaft itself. The failure to effectively control these dangerous torsional vibrations can cause catastrophic engine failure.
