From
Andymark's website each CIM produces 337Watts at maximum power.
337 per CIM * 6 motors = 2022 Watts per transmission assuming no power loss.
1 HP = 745.7 Watts (1)
2022/745.7 = 2.71 HP per transmission.
Edit: This is why using stall current for power doesn't work for DC motors

In other news, I just realized why some people use 5310RPM as the freespeed of a CIM. Assuming the CIM behaves like described in the MIT coursework, peak power occurs at 2655RPM and in the middle of the RPM range. Doubling 2655 yields 5310RPM as the max RPM for a CIM
