This fluid damper was designed to dampen out higher rpm, 6000 to 9000 rpm harmonics which are the most damaging. In fact the oem damper starts to pick up a harmonic above 8000 rpm that twists the crank quite a bit.

That being said, it will counter any vibration that starts resonating, it is simply more effective or focused at higher rpms.

In our experience resonance in that range could be clutch related.

 

Some good reading..

The Silicone Gel is quite viscous when installed into the Fluidampr. Works from -40F and designed to absorb and dissipate heat.

The S2000 Damper was tuned like the Fluidapr Gold Series with out the gold, focussed on 6-9000 RMP. The engine starts to vibrate badly above 8K. Our damping test show a spike above 8K on the OEM damper, Fluidamper catches it before it resonates.

Also some FAQ stuff..
Does temperature affect the function of Fluidampr/Streetdampr?

Silicone fluid is a very good damping medium because it is relatively unaffected by temperature changes. It provides consistent damping in both winter and summer. The fluid will not deteriorate if the Fluidampr/Streetdampr is not used for a period of time.

Does the Fluidampr or Streetdampr require "warm up" before use?

No. The silicone fluid in the damper will deliver consistent performance over the entire range of operating temperatures in any operating environment that the damper will encounter.

I had this damper on an engine several years ago or my Fluidampr/ Streetdampr has been sitting on the shelf while I have been finishing my engine. Will the part need inspection or testing?

No. The inertia ring is always freely floating inside the housing. The silicone fluid is guaranteed to last forever. As long as the damper was never physically abused (hit with a hammer), installed properly with an installer tool or a bolt and washer, and as long as the damper maintains a tight press fit on the crankshaft, there is nothing that can go wrong with the damper. It is important to check for corrosion or pitting on the seal surface of the damper, before installation. The seal surface should be smooth and free from rust and corrosion. As with most any performance part, if it is physically damaged from an accident or a fire, the damper should be replaced.

 

here are datalogs graph about my s2k with and without the Fluidamper pulley installed
same setup for both .
You can see how much less of vibrations the knock sensor did detecte with the damper ,even riding with hotter IAT° and hotter ECT°

 

Great stuff. Scientific proof of reduced knock due to reducing engine vibration.

 

Had to change that a little.
