I've got a barracuda on my 220. It's pumping at something like a 12 foot head and I have the output valve at around 50%. Still enough water to push my dual 1.5" overflow box and DIY 1" overflow. Had some trouble with the first barracuda I received. I contacted reeflo and they sent me a new one in a week and gave me a month to return the other. Great pump, even better service.
