I guess I'll chime in as well.
I saw the B-Line kit a few years ago and really wanted to design my own, but time constraints prevented that, so I called them and ordered just the brackets and designed my own kit around that with a Mocal sandwich adapter and -10AN lines.
At the same time I figured that if I was going to mess with the oil system, I might as well install the accusump I was eying.
After I had everything installed, I found the location of the cooler to be sub par for my application, it was simply sitting too proud, as in too high in the scoop, causing air to hit the front rather than the fins of the cooler. So I took a saw and chopped some of the "feet" of the bracket, about an 1" worth, until the cooler was almost flush with the hood.
I drove the car for a few weeks like that, noticing a big improvement in oil temps, about a 20F reduction and never going over 210F on the track, where with the stock cooler I was sometimes hitting 230F.
This was all with a scoop without TMIC internals.
Then I figured it could not hurt to install the scoop internals and modify them to fit... Best idea ever! The temps dropped another 20F! The general rule of thumb I found is that the oil temps, after warm up, are now at about ambient +100F. This means that if I'm cruising at 60mph and it's 60F out, the oil is 160F. But on the track it never get's over 200F.
I am currently designing some machined brackets that will allow a 25 degree tilt, and about 1" fwd/aft movement of the cooler, to align the fins in the airflow better.
As for the person who said that the TMOC heat soaks, yes that's true, but it only takes about 15 seconds or less, depending on RPM, to get the oil temps down.
All in all, a great idea that still can use some refinement, but works great as is.
