I got the charts (below) from the Opcon site. The charts reveal that the continuous rpm of the 1200AX (the model Whipple we use) to be 14000 RPM (top chart) and Max RPM of 15000 (bottom chart). When I get the time, I'll measure both of the pulleys and figure out what the "shipped" rpm of the Uber is.
The bottom chart will involve some deep thought to try and figure out exactly what it is telling us.It kind of looks like a topography map will a hill in the center ;).
