I have a 22" Wizard w/shroud ( 1" tubes ) and running 180 t/stat and clutch fan. Mild 360. Runs 180 degrees . On a hot day may creep up to 190/195 if I'm idling getting staged for a main street show. One of my best investments. They are a little pricey but worth every dollar. One extra thing I did was to install a sacrificial anode in the water jacket on the intake to protect the aluminum from corrosion.
