I think my issue is resolved. After installing the original radiator instead of using the one on the test stand, the engine got to 180-185 degrees after 20 minutes. The right bank is still 3-5 degrees hotter but I wouldn't even know that without the pyrometer. The test stand radiator is a horizontal flow but the original radiator is a vertical flow with baffles to mix the water left and right. This special radiator is necessary with the V16 that has two inlets with separate water pumps and two outlets.

Congratulations.

Now you know why it is important to use factory stuff wherever possible.

Us "hotrodders" try to reinvent the world, but don't have the technical ability of hundreds of factory engineers, or the funds for R & D like the Factory does.
