I just installed this same set-up, and even though it's supposed to turn the
fan
on at 185, it doesn't kick in until 195, and shuts down at 180. I know my temp
gauge is correct, since I calibrated it with a reference thermomoter, and it's
dead on from 120 to 212 degrees. I'm going to try soldering a brass lug
directly
to the side of the top tank on my radiator, and thread the thermo switch into
that to try and increase the accuracy.
Also, the current 10" fan I have installed is rated at 680 CFM, and just desn't
seem to have much affect, so I'm going to upgrade to a bigger fan with 1000+CFM.
BTW - I installed the fan inside my bugeye bonnet shroud, so with the bonnet
closed, the fan is located about 1.5" infront of the radiator core. I like this
set-up, since with the bonnet open, it doesn't affect the cosmetics of the
engine, also, I was able to make up a bracket for mounting the fan that
required
no drilling/modification of the body, and it can easily be removed.
