I just sent Grimmspeed my new in the wrapping VF46. I asked them to flow bench it to get a cfm. I haven't found a chart for one nor any static cfm data. Since I've seen cfm on almost all the other VF's we have for our Scoobies I want to see where our 46 stacks up. I will post it when I get it as I am sure Grimmspeed will let any who are curious know as well. I want to know before I pick my injectors and pump.
