On both of my supercharged bonnies, the temp usually remains around 195 degrees as long as the car isn't stuck in traffic, or it isn't a hot day, but that'* not always the case - sometimes they both operate at around 220 degrees (slightly to the right of the white tic line near the 1 o'clock position on the gage) even at freeway speeds when it'* 70 degrees F or cooler outside. Sometimes when that happens I turn on the AC to force both fans to turn on and that always brings the temp back down to around 195.
Most of the time the temp swings from 195 to 220 on both of mine. Isn't this nornal?
