I know I am quoting an old post but since there are some new posts on it I am going to clarify.
What I had said is that when running the smaller 2.35 pulley you are more prone to belt slip. You will have less belt contact area and you are spinning it faster. Does this mean that you are guaranteed to have belt slip? NO. You are just more likely to have it with the smaller pulley than when you run a 2.55 pulley with the 10% overdriven lower (around the same overall percentage of overdrive, but you have more surface contact area).
