You can add as many motors as you want* and your final speed isn't going to change. Motors increase torque, but not output velocity (if you have one motor at a thousand rpm, and you add another motor at a thousand rpm, the first motor isn't suddenly going two thousand rpm). Torque is calculated linearly. Double the amount of motors, double the amount of torque.
*This is assuming all motors have the same or similar output speeds. Of course adding a motor that's twice as fast as the original motor is going to speed things up a bit, but that's a situation you should rarely come across in FRC. CIMs and Mini CIMs, for example, are about the same speed.
