| If you look at core charts, something doesn't make sense P/N 2-220 shows a flow of 540cfm
P/N 2-221 shows a flow of 1080cfm The only difference between the two is the dimension they call "W" (which one would assume means width) doubles from 9.24 to 18.48. However, this is should actually be a height dimension, not a width dimension. As Height goes up, flow goes up. As the length of the core gets longer, the flow goes down due to increased flow resistance. I don't see anything on their chart that closely resembles the UAS cross flow style FMIC. Per their nomenclature, we should be looking for a core that is 3.5"D x 6"W x 24"H....it isn't there. Internal flow area is what will have the biggest impact on pressure drop. The UAS has an internal flow area of 3.5" x 6", which is rather small. Also, I don't think Spearco bar & plate is going to be drastically different from any other bar & plate. I'm also curious at the pressure drop these flow rates are measured at.
