The damper does a pretty specific thing - it snuffs out resonances at the natural frequencies of forged steel in order to avoid crazy harmonic crank twisting torsion. Based on my research ATI is the top dog in this field - they're the official NASCAR damper supplier and they have lots of great reviews on other car sites - so I'm confident in their approach even though it sounds kind of simple. And it's only a one size fits all solution because our cars generally fall below the thresholds that, in their experience, would necessitate a change in design; few, if any of us, plan on exceeding 550hp and 7500 rpms. Except bluejeansonfire
