Design Manual for Power Transmission Belts
One or more Vbelts may be used on a drive, as required, to transmit the horsepower load. In general, the drives are in the integralhorsepower class as distiguished from light duty of fractional horsepower drives. This manual covers three Vbelt cross sections and pulley groove sizes designated 3V, 5V and 8V.

Vbelt drive could have been allowing slip and hence affecting fan speed and load. In other words, the "5% increase in efficiency" was likely the result of variances in one or several drive parameters when the belt drive was changed over to synchronous belts, but was not necessarily a function of the change in belt types. It is possible

sideflexing belt or chain. Next, select the pitch of the belt. Pitch is the most defining characteristic of a belt or chain. Smaller pitch reduces chordal action and vibration, has less noise, can achieve tighter transfers and use smaller sprockets. Larger pitch belts are usually stronger and thicker for more wear and impact resistance.
