The Mendel 90 instructions suggest you run the Z steppers in series. That way the steppers see the same current as they would normally and the drivers deliver a little more voltage than they would normally. Works well with the kind of NEMA17 steppers we use for repraps.

No it doesn't reduce the torque as that is proportional to the current, not the voltage. And current is set by the stepper driver at 1.25A. It does theoretically reduce the maximum speed but I actually think that is actually limited by mid band resonance on the Z drive.
Other benefits of an increased rise time include higher operating torque and higher mechanical power output. As the rise time improves, the winding will spend longer periods of time at its rated current, therefore producing a higher time averaged torque.
