I was considering this mod, but then I realized that the temp guage never gets past half-way. I made a short trip last weekend, forgot a key and came back to the house. When I went in, I left the busa runnin'. I was inside for almost 10 minutes looking for that damned key, which BTW was already in my pocket with me - I had not forgotten it. Anyway, when I came out, I checked the temp guage - it was just barely cracking 1/2. By the time I went down the road 40', it was back under 1/2. Cooling system is stock, I haven't even flushed the original coolant yet (winter maintenance this year). I guess if she ever does start running hot, I'll do the fan mod.
