The HHR fan was pretty popular around here for a long time. Champion and others sell a fairly economic replacement aluminum radiator for most old Mopars. Seems like a good combo for many here

I still have my stock radiator out of my 1972 (340) Duster sitting here that I had recored 30 plus years ago. A neighborhood shop did the work for me and it fixed all my heating issues. I tried selling it after matt and I switched to alcohol but typical mopar guys wanted it for next to nothing so I leaned it against the wall in my basement. Who knows maybe I will build a street car after I’m done racing.
1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27

I use to kill the alt but a couple of years of doing that I didnt see any change in ET and went back to keeping it on.. I use to use a L body rad and the small fan that was on it.. on my Rampage I use a Summit rad and the HHR fan fit my rad perfectly.. I do want to add 2 spring loaded flipper doors to it for a bit more flow I use a 2 row 3 pass rad

ok- at 50 amps of load it costs 6 to 8 hp with windage costs.
if we had a clutch system that would disengage the shaft- we could see real differences . something like a blower clutch on smaller scale would work it would seem. The math i'm looking at indicates we could be seeing losses of close to 20 hp depending on battery condition, amp load and alternator windage.

Its the draw you need to worry about.. if your draw is low the alt wont do much at all(low out put)

Why on a bracket car would you worry about cutting the alternator on a run. It is a shoe polish race so how could it be on any benefit? FWIW we run an alternator on the heads up car it sees 10,000 rpm on a regular basis and keeps all the racepak and ignition stuff happy. Just a question, as I cant see any benefit from turning it off.
