I think that 2 mini Cims would put you around 115lbf at peak power. Do you know what resistive force will oppose your motors? If so you could find the motor speeds. Remember though, even though this is peak power, it's not peak force, which could be about twice these numbers.

Also keep in mind the current draw. If you are running a CIM at peak power it pulls ~65A, and at stall it is like 130A. Depending how long you are running under these conditions you will have to consider the tripping he fuse.
