I just turned my Grizzly 2HP DC into a cyclone with the Super Dust Deputy XL. Really happy with the results, but I was wondering if changing the motor itself to a 3HP would be that much better? My dad works on electric motors so I can get one for next to nothing, but just wanted to make sure there wouldn't be any hinderence on something like the impeller size or something.
It has a 12" steel impeller.
Also Grizzly rates the 2HP motor at 3450 RPM. The 3HP motors I'm looking at are 3450 RPM. Is Grizzly really giving the correct RPM on their motor?
