Small CIM has a free speed of about 5300 rpm - however at 40 amps it is more like 3800 rpm.

Therefore in high gear that would be between 404 rpm (40 amp) and 564 rpm (2.5 Amp).

Low gear would be between 158 rpm (40 Amp) and 221 rpm (2.5 Amp).

The speeds are the same whether you have one or two CIMs. Having two Cim's just doubles the torque
