That looks to me like a lot of heat exchanger. Do you know you need that much? What oil temp do you maintain at high steady-state power levels?

I have the pressure side cooler plumbed after the oil filters and then into the engine main gallery. That is the cooler at the far right in the picture. That cooler has air plumbed from the parking light opening.

The two coolers on top of the radiator plenum are plumbed in series from the scavenge side of the pump (removes oil from the engine) and then into two Peterson inline filters and then into the holding tank.

Oil pressure is always 100 PSI no matter the oil temperature.

Coolers are 44 row.

How many row are the Setrab oil coolers you are using? How do you have them plumbed? Do you have any pictures of your setup?
