The SCCA thing makes sense, but the external engine oil cooler falls into the same category. A street 951 that runs around on 1 or 2 psi all day, with an occasional 5 second burst to 15psi probably has oil temps barely hotter than an NA, which has no external cooler. I'm keeping my trans cooler, engine cooler, power steering cooler, brake ducts, intercooler, and 4 piston calipers.....none of which I need more than 1% of the time on the street.
Its really not worth debate, though. The OP is probably happy with the "no cooler required" results.

I know on an automatic I would always run an external cooler, but I didn't really know if my car needed one or not. I have one currently but its an 86.

The reason that Porsche had trans coolers on the 1986 models was that in the 944T was competing in the SCCA Showroom Stock series, basically against the Corvette. I believe the rules for 1986 were that the car had to be stock and equipped with only standard equipment and possibly priced below $30,000. So if the 944T needed an oil cooler to make the trans. last thru the race, it had one....std equipment. The 944T won the championship in 1986. In 1987 I believe the rules were changed, so no more standard trans. cooler on the '87s. Anyway that's what i recall when I bought mine in 1986.
