Re: IML: Question about harmonic damper

["rob van der Es" <r.vdes@xxxxxxxxxxxxxxx>]

Thanks Dave,

But apart from the fact that a standard damper is good enough when it
comes to max rpm, what about the fact that a fluid damper works on a much
broader rmp range (thus damping vibrations within a much broader range,
rubber dampers are "tuned" for a specific range) ?

Have a nice day too,

Robert
