I have seen some stock gauges that don't start moving until 230+ and some that moved at 215. So it will be interesting to see where you are once you get the aftermarket gauge installed.
FWIW: I experimented with electric fans years ago on several cars and never could get them to work to my satisfaction so that is why I am interested.
