RPM isn't directly a factor.
The question is: will the engine operate at a higher RPM which includes another destructive harmonic order? If yes, the damper design is different.
Mistakes from 50 years ago: Ford 289 210 hp owners install high-perf 271 hp and Cobra parts, including the cam. The 210 hp low-perf damper does nothing above 5,000, the 271 cam works above that. Wrong damper: broken crank.
