Re: IML: Question about harmonic damper

[randalpark@xxxxxxx]

For what it's worth, I also suggest rebuilding the original or 
replacing it with the same type.

Rob:

In the theme of originality, I am pretty sure that you can get you 
original damper rebuilt to better than original specs.  
For Imperial applications, you do not need a race damper.

I have never used them, but they may be worth contacting.  They seem to 
have many dampers.

Hi,

In addition to my earlier message of yesterday with regard to my request
for information I would like to add this link:


www.440source.com/dampers.htm

The first damper on this page is a stock damper (allthough it is SFI
approved..) and the second one is a fluid damper (just like Fluidampr is
selling for almost three times as much).
So I think I will choose one of those two.

Can anyone explain to me (Dick B. or Paul W. maybe ?) what the benefits
are of a fluid damper.
I have been told that a fluid damper is working better at a broader rpm
range than a standard elastomer (rubber) damper. Is this true, and will 
it
do my engine and bearings good because they suffer less from harmonics?

Thanks in advance for your help,
