O.K. I get the general gist ,aa=less r's per mph than a b cut ect..
, but I mean if say your looking at a dyno sheet and an hp/rpm impeller sheet, would you want to your max on the impeller chart to corespond with your peak torque or hp or somewhere center or ?????? BTW does an impeller/hp chart exist for the new hi-helix yet?? hint hint hint
