I'm running a NA LS7 with a lot less HP than Mark - about 600 - and I certainly can't drive my car as close to the limit as he does his But I still find PS and trans cooling to be essential for Summer track days, I think partly because temps never return to baseline between sessions. By the 2nd or 3rd sesssion, both steering and shifting went to hell by 10 minutes in without coolers. My diff temps are marginal - 260 - 280 with synthetic fluid - and I haven't added a diff cooler yet.
