Matt, how big is the intake if you pull the "Y"? 5"? 6"? I picked up the SDD from Oneida yesterday and the HF DC should come in tomorrow. Trying to lay out the plumbing and wiring. It would be nice if the motor can be switched to 220V but at the price i'm guessing no.
Tpt, I thought the same thing at first glance. All I can tell you is there are numerous videos of this setup running after the swap and I haven't seen one that said anything about bad rotation or poor performance.
