Worthy upgrade over an existing aluminum radiator?

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!

When constructing your system, make sure to seal all air leaks around shroud so that air is not going around the rad but through it. If you look at stock systems you will see the hood to rad support seal and how well the shroud fits to the rad, then you make sure that the distance from blade tip to shroud is close but not so close that engine torque will cause contact, then as I stated before the depth of the blade into the shroud is important.
I forgot the timing, Correct initial timing as far advanced as your engine wants will help with cooler running.

I run the 7 blade and clutch on the charger now. Strangely, a flex fan and shroud works as well or better on the fury. Maybe the original clutch wore out. It's pretty annoying that there's no bench test for them

I don't believe there is any way to bench test them, however if it's installed on a running car, you can test it with a rolled up newspaper, or the like. Wait until it's warm, then gently stick the rolled up newspaper in the fan. If it stops, it's no good. If it makes confetti, it's good.

It's a crossflow radiator with no provisions to mount an OEM style shroud, that's part of the problem. The end of the fan clutch is about an inch from the rear face of the radiator core.

I agree that a shroud on the current radiator would probably fix it, but any of the reproduction shrouds won't fit due to the locations of the tanks, and my fab ability isn't good enough to make something that looks nice enough that I'd like to have bolted onto the car.

Any competent sheet metal shop should be able to make you a shroud.

If you are really wanted to stay with aluminum rad, go with your idea of aluminum rad with top tank and mounts for original shroud.

I wouldn't be so worried about sick week or drag week, power tour had some nasty backups the one year we went.
Though I did get stuck for 20 min leaving Byron last year cuz of construction. Good thing I had the hellcat
