Agreed. The only reason to run 10-AN is if you put the cooler all the way up front.

The temperature was controlled perfectly in my old system, 1.5 qt. sump, full flow, Gene Berg pressure relief cover, thermostat, and cooler in the back in the spare tire area.

Ed, I think you know I've got a dry sump now.

8-AN works perfectly in short runs(within the engine bay), it's what I have on the cooler side of things. Pump to thermostat to cooler to oil tank. It's also what I have on the pressure side of the system, pump to filter to main oil galley.

In the dry sump system, there are two paths and two separate pumps. You have a scavenge pump and a pressure pump, and an external oil tank instead of a sump.

Engine running, the engine sump is dry, my dipstick shows no oil. 

My engine temps run a bit cooler now, I think the cooler is more efficient since it is on the scavenge side, plus I've got my home-made sled tins exiting that hot air rearward instead of down.
