From what I can guess it's to help minimize wear in the mod class to avoid belt slippage. You might be able to run a slightly looser belt since the teeth in the pulley tend not to change as much as they would with a plastic pulley. It could also be that some of the team guys were breaking pulley's in the 416 in high traction situations - I know I've never broken one but I also don't run 3.0 turn motors boosted either.
