Fluidampr harmonic damper - for race/track only use - Experiences?
I know some NA street/HPDE, and FI guys use these, and they are particularly beneficial at the low Frequency/RPM spectrum, and offer broad dampening without a need for a specific tune region, but who out here is racing with one? Or at the track long-term with a Fluidampr?
I bought one and it's been installed from the very first time my car went to a track, but upon a lot more in depth digging, it seems that the Fluidampr is actually worse than the OE damper at controlling high frequency, high RPM vibrations. These are the worse kind to have because they happen more frequently and affect crank driven components like timing and oil pump components, etc. Lower order/frequency vibrations aren't as damaging a they don't happen as often, as can clearly be seen that the OE damper is concerned with controlling those, for long-term health of the motor.
My car only sees the track, so their marketing data regarding the lower frequency, and lower RPM vibrations don't have much meaning to me, as the vast majority my RPM's are 5000-7500.
I'm not interested in the underdriven ATI, so I'm seriously considering re-installing a new OE damper for better long term high RPM dampening.
Even their own data clearly shows the OE controls vibrations better in high frequency, which is why they decided to compare it to the undamped, lightweight pulley for marketing purposes. Not bashing the product, I own one, and think it works, but for a more specific use, like full time track, I'm beginning to think this may not be the best option.
The other part of the equation is the LWFW, that virtually all of run. It's known that using a lighter flywheel can shift some vibrations to a higher frequency, and while it's not a huge concern with our boxer motor, using a "heavier" lightweight flywheel may also be beneficial. I'm actually going to replacing my ACT "streetlite" setup with an Exedy LWFW/Sachs clutch, which is about 1lb heavier, to also help provide more dampening.
Feedback or experiences are welcomed, I can't seem to find many discussions on this topic.
