    This is generally limited by the physical  construction of the motor 
(bearings, balancing, load, rotor strength). Best to  contact the manufacturer or 
review their literature for the exact motor you're  using. IMHO 3000 rpm 
should be no problem for most 1740 motors, especially for  occasional short RSG use.
    Also keep in mind once you hit 1740 RPM, you will  be in the constant HP 
region, so further increase in RPM past the motor's  nominal rating come at 
the price of a linear decrease in available torque.
