I have a Chrysler small block performance book written by Larry Atherton way back in the day, a Chrysler engine book from back in the day, and a current stroker small block book by Jim szilagy.
All 3 books claim that the number one improvement to improve pump output is to increase the diameter of the pickup tube.
Two of those book are written by Chrysler performance engineers.
None of those books claim any problems with the screen on the pick up. That's the best I can do as I was never that good at math lol.
