Ideally you want to run your engine @ full rated Hp--3600
and if you have the hp to run the thrower fast/faster(not the engine) it works better.
Granted, there are instances where slowing it down is desirable like not wanting to blast snow @ a building/vehicle.
But keep it's mouth loaded and gov full open, especially in sloppy wet snow.
An operator gets a feel for how fast/slow to go by engine sound and where you want/how far you want to throw it.
if one is modifying the ratio's, trial/error is the way to go.
When you get too much auger speed you loose Hp real quick,
too slow and if just glops out like the rear end of constipated dog.
