The advantage of the poly-v over a cogged (synchronous) belt is that they
naturally dampen torsional spikes, by means of slippage. Another plus is
that the pulleys can be considerably lighter.

Get a clue. Compare efficencies between a cogged belt sized for 100 HP,
and the necessary number of v-belts for the same 100 HP. Next, take that
percentage of power wasted for each, and calculate how much heat will be
produced by each of these two systems.

Should be no problem for a math wiz like yourself.
