I have found Rotrex compressor maps the show data to 120K, so someone (Rotrex) has spun the -81 that fast. I think we all be safe with some overspeed. I ran the 84mm for 10K miles and my blower did not pop.

You are only overspeed when you are turning the engine near redline. If you want to be safe, reset your max RPM to 7K with Up-Rev.
