TF & Speedmaster Flow Tests

I will stop here and say that PBR told me a couple of months ago to increase the area at the apex and get the velocity down and that is probably the real solution, but I don't listen so here we are. Momma always said if I had been her first child I would have been her last.
Just curious what is your Cross section area is here ?

I've seen Eric say he finds it's generally around peak flow # when he's done, so 300 cfm = around 3.00", 275 cfm = 2.75" etc..
