High performance damper

[Southern Ram]

I saw today where Fluidamper has introduced a harmonic damper for the high perfomance Cummins 5. 9 folks. I got the info off of SEMA's web site.

Cool! If any engine could benefit from the Fluidampr, it's definitely a CTD.

I heard Fluidamper was out of business????? I heard that a while back, I also heard that it was because of quality control issues????

Excuse my ignorance but what exactly will one of these do?

Wow, I've been on TDR for 5yrs & 3mos and this is the first time someone's brought up the subject of an aftermarket damper. Cool!



Double J they are beneficial in taming crank torsional vibes, which an inline 6 is the most susceptible to because of the looong crankshaft. Fluidamprs are a must for guys building hot Chevy sixes or Slant Sixes. Without them you have more bearing wear and possible crank breakage.



Basically when your front cylinders fire it twists the crank throw slightly ahead, then when the combustion is ending the throw recoils. The crank damper absorbs and lessens this shock. Stock ones work fine for stock power, but are inadequate when you crank 'em up.



The Cummins seems to have such a beefy bottom end this hasn't been an issue. But since we BOMB anything else, why not BOMB the crank damper if we can??

Thanks for the explanation Vaughn. When I attached the RASP to it I was wondering what it actually did and if it would have any side effects with another pulley hanging off it.
