With the given information, you should expect to see between 6.5 and 7.0 ft/sec.

In order to reach 31 ft/sec, you would need a final gear ratio between your CIM motors and the output wheels of aproximately 4:1, depending on where in the speed torque curve you would wish to operate at. For comparison, the first stage in the toughbox is 3.57:1.
