Actual RB211 RPM

[SB4200]

I remember seeing some time ago a thread about what RPM engines such as the RB211 actually spin at. Unfortunately the 4 character minimum in the search function doesn't lend itself to finding a lot of topics in this TLA full industry and I can't find it.

So i'm interested in either finding that thread, or alternatively, could someone tell me what sort of RPM each spool is spinning at at 100%?

Thanks
