Fluidampr
Anyone using a Fluidampr harmonic damper?
What are your thoughts?
I have a 7.4 liter BBC in a Suburban and its harmonic damper seems to function ok but it has rust, age, and 200,000 miles on it. I was thinking of just putting a stock damper on it but when I was looking for one I ran across the Fluidampr and wondered if it could help the BBC in the smoothness category.

What's interesting about a fluid dampner you can't balance a crank with one as it will not repeat twice and it does through the rear off as well.
When you balance with a fluid dampner the outter ring has to be taken off.

At 200K in a suburban I'd just get a stock one.
Otherwise I lean towards ATI exclusively. Not too wild about the fluid ones unless its a very limited RPM range....like the diesels they were designed for.

A fairly more expensive Fluidampner would be an unnecessary expense. U would be better off using a inexpensive stock dampner and spend the difference in $$ to buy a new timing set.On the other hand the Fluidampner's are not expected to wear/rot out like a stock elastomer dampner.
Hope this helps ya',

Cheap stocker, the way they can oscillate is a good thing in terms of crank twist, etc.
I dont know this for fact but I have heard of a few cases where, in freezing temps the Fluidampners have failed and caused damage due to the fluid freezing. True, who knows
With that said Ive used them on two different motors, happy with them .

I know of at least 3 crankshaft manufacturers that don't recommend fluid dampers. This technology comes from low rpm diesel applications where the dampers were matched to the rpm the engine would be running for most of its life. These engines recieved the same crankshaft and other components in which the damper was tuned for. A Bryant billet compared to an Eagle 4340 crank with the same stroke will not have the same harmonics.
