These used to be all the rage and in every magazine build. Now I never hear them being used in these huge 1000+hp Viper builds. Tons of vibration and harmonics in a V10.

I have an IPSCO pulley that needs to be installed so changing out the damper at the same time would be simple.

Any input? Thoughts?
