Here’s my input, I ran at one time on my Cat a 5DS 601hp/2050 in my 5EK series with 58’s. It was so much fun to drive. Almost like driving a pick up truck. Only upgrades I did after running that file was a Borg Warner stage 1 turbo and a 4 row 3/4” dimple tube radiator. I never ever had a heat issue with the pyro heat nor coolant temperature.
