Anybody running a 100amp alt on their race car?
.......... delta or a "Y" junction armature......... I run 60a squarebacks in both.
I don't think it's that simple. There are smaller rated squarebacks that put out MORE at lower RPM than the 60-65A units.............BUT...............
In this day and age where we have the awful quality of hammer/ slam / rebuilts, it's doubtful that what started as a 60A, a 55A, or whatever, now retains it's original armature, and certainly not stator. What I mean is, what was original, no longer is.
(What happens, example, if a rebuilder stuffs an older, roundback stator into what was a nice squareback?)
Seems to me that "newer is better" so far as output performance, although my car, which has no special needs other than EFI, still runs an everyday squareback.
