Your charger behaves the same way with the same equipment. Dad had electric fans on it and when I brought it to the city it immediately started overheating. OEM clutch fan made it much better but the temp creeps in summer traffic jams. 100% a shroud would help but I haven't figured out how to make one either for the universal rad. If I ever go on 'Tour with it I'll need a different solution.
We're definitely in the same boat! I got accepted into Sick Summer so I'm worried about the traffic jams getting into a couple of the tracks. Have been spending money hand over fist on it, lol.
Summit's site also allows searching fans by size, and they have the OEM electric ones in there as well. The HHR and Contour fans fit great on a Mopar sized radiator core but the crossflow one I have is narrower so I can't find a decent electric solution. Like Kevin said, the aftermarket single 16" fans are crap compared to some of the OEM stuff.
I do have a 160* t-stat in it already. Will start by trying to put one of the universal shrouds on it and get the clutch spacing right. Thanks guys!
