I was using my prototype oil cooler kit and in the 4th session oil temps were around 255, in the 5th session they were around 264.
Those oil temps seem pretty good considering those hot ambient conditions :thumbsup:
Looking forward to see you bring the OC to market and order the whole cooling suite

Yeah I'm quite happy with the numbers considering the conditions

The oil cooler kit will be ready quite soon and then I can make a full post about it

Could you explain the difference in design from your prototype to the final version?
In this earlier pic, the coolant passages are going sideways and there are end tanks on the left and right, with the offset seams that show the back and forth path of the coolant.

In the newer photo, the coolant passages are vertical, and there's no sign of the end tanks on the left and right. Was this turned 90 degrees? Are there internal dividing walls in the top and bottom end tanks now to implement the 3 passes? Can you point out the seams?

Thanks.

Good catch! The PWR design seems to be vertical flow? Which probably explains the how they were able to achieve the more compact design.

You are correct that it is a vertical path now and no longer a horizontal path. Here are some pictures to help show this:
