and mopar and canton and moroso use a screen on the pickup cuz it is around 85% open and 15% metal, where the restrictive milodon intake with a bunch of drilled holes is a "nice restriction"-Smokey Yunick - 50% open and 50% metal
I would be looking at the total flow area of the pickup opening, not the % of surface. If the total area is still a lot larger than the flow area of the tube, then it is not likely any issue.
Thanks for the info on the dual pickup, BTW..... lots of good info here.
