CTRE Mag Encoder: Max is 15000 RPM for the relative mode, 6600 RPM for the absolute mode. If you need faster than 6600RPM and absolute mode, you can just set the relative sensor position to match the absolute and use relative from then on.

MA3's also have a max of 15000RPM.

Checkout the magnetic encoder user's guide for more info (particularly section 5.3)
