Do you have a link for the oil drain plug you are talking about?
Here is a link to the fumoto site. You can also get them on Amazon. I like them so well, I put one on my car. They seem to be well made.
I love mine .... just open it and let it drain ...
Mine starts up around 60psi and hot idle is still over 40psi, 392 oil pumps flow more than 5.7's and Hellcat's flow even more. I didn't do the Hellcat pump because the 392 piston squirters are different than the Hellcat, I was kinda scared how this Hellcat oil cooler would affect with 6.4, but its been really good, not sure how it would behave with the 5.7 because of the smaller oil pump, I'm sure the Hellcat pump flows more for the bigger oil cooler.
I would advise against these, FRAM made one back in the day, and I had it on my Vortec 5.7 and I noticed it was running funny so I pulled it out and tons of sludge came out of my oil pan, because the fitting goes further up than the bottom of oil pan and doesn't drain it all, my truck only had 50k and I had to change the engine.
How are your oil temps while under heavy load mixed with a little red light traffic or long Steep grades (again with heavy throttle, even WOT)?
Yeep, these don't stick out into the pan .... I checked myself before I installed it because I was concerned about this as well
Nope, not true, I checked myself before I installed mine on my truck, doesn't stick out into the pan at all ...
Any idea if there is valving or a bypass inside the adapter? Also curious if the adapter can be run with plugging off the cooler fittings?
Great, thanks! I was hoping it would work without cooler lines.
