Diff. pulley... SIZE matters ?

Bigger is better. The belt is wrapped less tightly and is in contact with more teeth at any one time, so transfers the power more efficiently.
The compromises come with packaging, for example driveshaft angle and the height of the CofG.
Seems like pulleys in the high-30s, low-40s are about the limit on a touring car. A few years ago the pulleys tended to be in the low-30s.
