Start Your Engines.

In the mid-1980s professional race engine builders approached Vibratech TVD. They understood why a viscous damper would benefit them.  Our mutual challenge was to apply Vibratech TVD's extremely durable, commercially proven crankshaft viscous damper technology to motorsports. The Fluidampr brand was born.

MotoIQ.com Tests Fluidampr Performance Damper.

Posted by Brian LeBarron on 9/20/17 11:24 AM

Fluidampr® performance viscous dampers are a fully owned product of Vibratech TVD. They are the leading viscous damper in the performance racing industry and can be found on an OEM endurance racing team down to the grassroots level. Professional engine builders install a Fluidampr performance damper as a fundamental building block to help achieve long term durability. Increases in torque and horsepower are often realized as a result of improved efficiency by minimizing torsional vibration. Recently, our friends at MotoIQ.com, a prominent automotive performance digital publication, discovered just that. They achieved a whopping 12 whp peak gain at 5,600rpm and 19ft-lbs peak gain at 3,650rpm with their Volkswagen Golf R MKVII project car.

Crankshaft Damper Development Case Study

Part 10 - Forward Thoughts

Through this crankshaft damper development case study we focused on the creation of a Fluidampr brand viscous damper for the Subaru FA20 / Toyota 4U-GSE engine found in the popular Scion FR-S, Subaru BRZ and Toyota GT86. While this particular damper is intended for the performance racing industry and automotive aftermarket, two main take-aways for any engineer from reading the series are:

Crankshaft Damper Development Case Study

Part 8 - Crankshaft Torsional Vibration Test Results Continued.

Vibratech TVD’s goal throughout this case study is to make a Fluidampr® performance viscous damper upgrade for the 2.0L opposed-four Subaru FA20 / Toyota 4U-GSE engine. In Part 2: Crankshaft Damper Design Criteria, it was discussed that the damper needs to provide optimum damping across a broad frequency range to meet the challenging demands of the performance racing industry.

Part 7 - Crankshaft Torsional Vibration Test Results

Previously we discussed the objections we were testing for in determining the validity of a viscous damper upgrade for the Subaru FA20 / Toyota 4U-GSE engine found in the Subaru BRZ, Scion FR-S and Toyota GT86.  While the Fluidampr® performance viscous damper in this case study is a product of Vibratech TVD, powertrain engineers benefit best when our ISO 9001:2008 design and development certified methods collaborate with your internal processes to ensure total quality.

Part 3 - Viscous Damping Solution

A viscous damping solution has proven to be ideal for the performance automotive aftermarket.  Most often, increasing cylinder mean effective pressure overworks a stock tuned elastomer damper beyond its intended tolerance to dissipate heat.
