On the outside more tension equals more cog teeth engaged. On the inside the tighter the pulley the 'less' cog teeth are engaged and seems like the would be more likely to 'skip' and throw the belt. Plus less vibration/harmonics/heat if the idler is on the 'smooth' side of the belt.
That's how I did mine on the Moroso water pump drive belt.
Home made using a slot car wheel/tire on an 1/8" shaft. ... round and round :realcrazy: lol
