Asking if anyone had any bad experiences with either ATI or Fluidampr Harmonic Dampeners? I like the fact that Fluidampr has one specifically made for the s2000 and can use the hex tool to remove unlike the ATI. But after searching around, seen more builders like Kings, inline pro, laskey, speedfactory all running ATI dampeners. Wanted to see what s2ki members have ran and hear their experiences. Thank you!

 

I would be interested as well even though I am running N/A. Anything to tone down vibration.

 

 

Also been using the Fluidampr for almost a year with no issues. Vibrations have been noticeably reduced.

 

This post reminded me of this...
ATI, Fluidampr and TCI Clear Up Damper Confusion - EngineLabs

 

We've used both, I've met with reps from both. Both are great products, but work on different concepts:

The ATI works on a similar concept as the OEM pulley. The OEM pulley uses a bonded rubber, the ATI uses internal elastomer. It can still wear out, but it can be rebuilt.

The Fluidampr is a viscous fluid - nothing to wear out - and it covers a broader range of harmonics.

 

Im also on fluidamper. So far so good! Didnt really notice a difference. Then again my aftermarket motor mounts and exhaust created more vibration and noise so its hard to distinguish

 

I've been searching for which damper is more effective at lower rpm. Like what every day street engines deal with. Logically thinking, wouldn't the ATI be more effective in the lower rpm range? It would seem the fluidamper would be more effective at higher rpm range as the damping effect would intensify as centrifugal force goes up

 

I googled purely out of interest and... the following link since to state the opposite:

I know nothing about these units though.

 

Mine seems to have lowered vibrations throughout the rev range - less vibes at idle, particularly. Other thing I've noticed is that clutch engagement seems smoother, maybe because of the damper's design or increased weight over stock, or maybe it's in my head.
