The Technology Behind Fluidampr
The best dampers on the market are manufactured in the U.S.A. by Horschel Motorsports, an ISO 9001:2008 certified facility. Horschel Motorsports is continuing the tradition that started in 1946, when the first viscous damper was invented.
What Is A Harmonic Balancer, aka Crankshaft Damper?
A harmonic balancer reduces destructive crankshaft torsional vibration, which is the end-to-end twisting/rebound motion, that is naturally generated during each power stroke. A harmonic balancer contributes to greater valve train and timing efficiency, plus reduces wear of critical engine components such as main bearings, oil pump and the crankshaft itself.
A harmonic balancer often incorporates the main drive pulley and by appearance is often overlooked as having no essential function to the life of the engine. If the drive pulley is incorporated with the harmonic balancer, removing or changing it to a lightweight design, or using a low quality product MAY BE THE SINGLE BIGGEST COSTLY MISTAKE YOU CAN DO TO YOUR ENGINE.Professional race engine builders approached Vibratech TVD, parent company to Fluidampr. The challenge was to apply durable, industry proven viscous damper technology to motorsports. It was the mid-80?s. Fluidampr was born. Today, racing demands a quality crankshaft damper that can protect engines across a broad RPM range. It needs to perform when you add horsepower and increase the temperatures under the hood. Racing pushes innovation in our design and manufacturing process. These advancements are passed on to our parent company, Vibratech TVD, and applied to exotic automotive, marine performance, and defense industry OEM applications. OEM factory race teams and grassroots Saturday night racers have made us the leading viscous harmonic balancer in motorsports. Hot rodders and restorers trust Fluidampr. Performance Diesel competitors value our diesel heritage and high-power experience. Import owners like how we optimize damper design and performance to their engine?s needs. We are all American made, shipped word-wide, and proud of it.
