Up to date information straight from the horse's mouth, if you will. It seems like you kind of repeated the original argument after this update which was made for a reason was explained. Probably any way can work. There are lots of variables since a turbocharger can be put on any engine in any configuration. OEMs use 2 bolt flanges on turbo drains a lot and you can get nice gaskets an OEM one might even fit.

Art, I appreciate the feedback. Like I said, I'm new here and as I see it this is a thread dedicated to best practices not BW official specifications. What I do see people missing (or maybe just me) is the bit about the feed line length. The official BW technical references states it should be no longer than 18" and get oil within 4 seconds cold and 1 second hot. I don't know how many people on this forum use the oil pressure sensor on the driver's side as their feed but if their line looks like mine, its close to 48" long if you mount it on the firewall. I think I will be trying to look for a closer feed as well as this drain issue.

Reviving this thread. Does anyone have a source or link to where we can purchase a proper oil drain?

I did, and I appreciate it. -10an may not be sufficient based on this thread and my communication with Full Race. In my experience -10an should be okay 99% of the time, but it seems like the efr will have better longeavity with something larger.
