I realize this has nothing to do with the filter, and you don't want dialog here ... so not sure how you want this to work ... but fwiw
@barry@3DM tells me in Grand Am racing they saw 20 deg drop in oil temps with Motul 300V.

My thoughts too, which is bitter-sweet. I feel like a 20° drop in oil temps from different oil alone would also be thought of as a stretch by most people though. Personally I'd be pretty happy to see a 10° difference in my car just from switching to magic oil, so I'm pretty excited for you. I'm inclined to think the oil is at least probably the biggest contributing factor, but I'm very impressed with that temp drop and (considering my general skepticism with big claims like that from any company) I would like to think the combo of oil + filter could definitely have contributed to you actually getting those results. Either way though you're lucky, it's not often in the aftermarket car world we see gains exactly in line with what manufacturers claim!
My apologies about what's below if you really don't want any discussion here, and I'll exclude myself from this thread if you want but I think these kind of posts are bound to pop up in some form. I'll try to stay constructive and inline with my interpretation of what you want, but considering you're the only person who physically has this in hand right now I'd like to discuss some theory:
It's (at least mostly) good to know you can blow through the new filter easier than through the Mann filter, I think that pretty soundly shows the K&P in and of itself should be physically capable of higher oil flow than our paper filters. That said, I still see where
@fmorelli is coming from 100% and I agree with him even though I think I'm more cautiously optimistic than he is so far in regards to potential "performance" gains. The garden hose and pool analogy is a really good point and raises a pretty important question for those of us who are interested: is the oil filter itself limiting flow?
1.) I've never seen it mentioned before this thread but considering some things the German mad-scientists did, I wouldn't be horribly surprised to find out that the DME targets a certain range for oil flow and doesn't allow us to exceed it. If that's the case, then we probably wouldn't see any feasible temp drops from the filter but could definitely be taking some stress off the oil pump system, and at the very least hopefully reduce the amount of filter bypass. Maybe people familiar with the deep inner workings of the DME like
@jyamona or any of the other MHD crew could chime in there.
2.) The other, bigger potential factor is whether or not the filter is even the bottleneck. If our internal plumbing isn't capable of out-flowing whatever the paper filter allows then we're pretty much stuck, much like how the standard DCI only outflows the plastic airbox & filter enough for 10hp without completely replacing the inlets. Admittedly I don't know much about the N54's oiling, but maybe people who've physically dug in to a lot of these engines or even sensor-and-data-crazy people like Tony or
@Chris@VargasTurboTech can shed some light on that.
I understand the desire for more scientific testing like throwing this thing on some flow bench or what your results would've been had you stuck with the same oil (which I personally was really hoping this thread would be about tbf) but honestly I'm glad to see you doing this either way. In the end chances are most people who will run this care more about real world road-proven results which you can hopefully provide us with.
--------------------
I know my post is already horribly, horribly long but since you want to make this a running results thread, would you be willing to pull the filter and take pics at certain mileage intervals for us? I'm curious to see what it looks like after 100, 500, 1000 etc miles. That should at least hopefully shed some light on its filtering capabilities and long-term sustainability.
