Avoid "shade tree engineering"! Don't just guess and try it, the build season is too short!

Belt manufacturers publish data on capacity of belts, advantages of construction and materials, etc. The data is often in the form of a graph, plotting belt capacity (in horsepower) against the speed (in RPM) of the fastest pulley. do not exceed the spec.

You should also look at the max torque. You will probably have to ramp up up the speed of the motor to avoid slipping the belt or the pulley.
