id go higher. the pressure in the system is dictated by temp, so by going higher, IF it does overheat theres less risk of it boiling and chucking coolant out. you could go way higher, the only drawback with that would be if its got really hot, it might blow off a hose or something before the cap released pressure, but the last thing you want is to release pressure on an already hot engine
id go with 92, to stop it shunting in and out too much,
but id rather see an 82 degree stat and set the fan to come in at 88-90
Thanks for this useful thread yellow. It'll save me asking the same questions if/when I finally get to that point.
