Those plates look very tidy and are along the lines of what I was thinking. Then I can put them on a scale before I rivet them on and get the totals for each arm the same. I find the 2 X 4.5 pins with a couple washers is ok for 17-18psi but I am looking to keep it away from the limiter with a little higher boost level without changing weight profiles. I can get it by steepening the helix but I don't like to have to do that as it produces a lot more heat in the clutches and loading the primary is the better way.
