I've not done any comparison, but I can certainly tell you that after 60,000 miles with both Rob's triple core radiator AND his refurbished steering rack, both were superb investments. As to the cooling, I run twin turbos which, as you can imagine, add some heat (pun intended). I have sat idling in 102º temp for nearly an hour and did not overheat. Going up and down mountain passes in boost also creates no problem. As to the rack - awesome, simply awesome - still tight as a drum after 60K miles. Oh, and to add my 2$ to the motor oil comments, I, too, use Mobil 1 and change as close to 3000 miles as I can. Not only do I not have "coking" problems with the turbos, but the oil is still transparent when I change it.
