As the topic states - I'm running a 997.1 Turbo Cabrio Manual with 28k miles on the clock - It's now running a Stage 3 FBO setup, with an AASCO lightweight single mass flywheel + Sachs 2.5 spec clutch, and quite happily spins past 7k RPM

Question being, how soon (if at all) should I look at fitting a harmonic damper? It makes sense getting one, especially considering the amount of chatter one hears at idle and low RPM - but I guess I'm just trying to get a gauge for how much of an issue harmonics actually are on a TT engine?

Given the chatter at lower RPM, and a rev ceiling of 7500 RPM, is the motor really at risk of backing out cam bolts / pulley bolts / flywheel bolts / cam actuators / breaking oil pump gears / shearing the pin & mangling the stock pulley?

I've found the Dundon item, which is basically just a rebranded ATI Super Damper... https://www.dundonmotorsports.com/996-997gt3-harmonic-dampe?carid=123 - It seems to be the go-to solution.

Advice / input / examples of failures would be greatly appreciated.

TIA gents.

 

Great question, I would love to get some professional perspectives on this.

 

Anyone?!

 

No one has any experience with this ? i am considering a light flywheel as well. Would love some feedback.

 

If Fluidamper made one for our cars, that would’ve been heavenly.

The rubber band style ones like ACT (Dundan) are wearable items unfortunately and targets select rpm unlike Fluidamper which covers multiple frequencies it seems with zero service ever needed.
