The flow vs delta-p shows to be about the same between the Ultra and the racing filter. You can have both high efficiency and flow with low delta-p.

Do you believe the posted numbers ? Those manufacturer provided figures seem just a little too consistent ... maybe the 3 gpm flow rate is too low to see any meaningful differences in flow restriction.
Read the rest of that thread. Delta-p vs flow curves will have a similar shape as flow increases (at constant oil viscosity), so having a data point at 3 GPM pretty much tells most of the story on how the filter delta-p will look at higher flow rates.
