I was hoping you'd weigh in. Everyone seems to conclude that the 4" UD pulleys demonstrate no negative effects on anything while at the same time, do result in very real gains in efficiency, power, and driving dynamics. That and our PS fluid doesn't burn through the reservoir and dump all over the track which is always a plus.
Have you ever cut and tested a crank pulley with a diameter less than 4"? If so, what diameters and what were the quantifiable results?
I figured someone most likely looked at this which is why I asked... Just to avoid wasting time/energy on a path thats already been exhaustively explored.
