Same, since 1992 with no issues.
Wizbang was telling me about an RCD Crank Support that utilizes an ATI Super Damper, but it is not a standard damper. I can’t find any info on it, but I think the hub was made from either 4130 or 4340 and double keyed.
With a real blower, making real boost, most dampers can’t handle the stress and will split at the hub.
