I have actually.
More or less on fordforums.com.au , theres a 3 page thread on Pro Comp alternators, a few problems here and there, some breaking on unusual places.
I was doing a bit of research on them for my panel van, seemed nothing from procomp is any good on anything other than a stocker. The distributrs they do are just knock offs of MSD and the likes but most people dont know until the go bang.
Anyways, its good its something minor and replacable, i know after hearing a few pops and bangs from a few cars today, they'll need more than a alternator.
Still love the way the wheels came out on your car, really finishes it off nicely
So she'll be ready for the track soon eh?
