I have had good luck reducing cooling system temperatures in my XKE, which is
also" temperature challenged" with Redline Water Wetter. When run with
straight water, it brought temps down 10-15 degrees. See this link for some
test data:
www.turbomagazine.com/features/0703_turp_cooling_system_additives/index.html
I've also read a research paper (although some time ago and I've forgotten the
reference) that said that the ideal operating temperature for longevity for
Ford small blocks was 210 degrees. Although not so good for horsepower, it
does maximize the oil film and distribution... perhaps one of the more
engineering connected Tiger folks out there remembers more about this study.
