Borat,
Your auger RPM was approximated from Maco's. Different belts but likely both pulley diameters are the same or very close. The estimate was 245 RPM per 1K engine RPM.
It would be interesting to compare impeller bearings. Murray and Maco both have roller bearings in the drive side of the auger shaft, flange on the other. Borat your's is probably the same. I'd have to check the Toro but I think flange on both sides.
The velocity out of a dual stage is 3400 to 4000 ft/min most common around 3700-3800 ft/min (that is if I am remembering those numbers right). The better brands of machines will all be at the top of the high end. Those numbers seem about right given what a Powerlite can do versus a dual stage in the back yard in conditions good for the Powerlite.
