The oil cooler was attached to the bracket so it was sitting horizontally. As for how it performed, I have no idea! I've never had it running.
I imagine it probably did work, getting air from underneath and the flowing through out of the engine cover vents. I agree on what others have said, some dedicated ducting will help!!

As starmag could not find his handbrakecables anymore, I thought, why not get my old overheated one off, and see if I can get it working again. Once off the car I bended it a few times, heard an felt some cracking, The inner cable started moving a little. half a can of wd40 in, and some black smudge out, it slides like nothing ever happened.
I reattached it and put a piece of tube around it where the cable is near the battery so it cant touch that again.......
Case closed
