Hey Evan, if 80amp isn`t enough the calais/statesman/caprice V8 ones up to VP/VQ s2 are 120amp which I'm pretty sure is what i have in mine. Well thats what i orded anyway.
Queensland starters and alternators did it for me(mate had the factory next door).
Gave 13.9v at battery which is in the boot, with all electrics on including high beams indicators, thermo, cd player, 2 fuel pumps, ecu etc. :dance:
lol. I didnt notice any loss in power mainly cause in the whole s/c upgrade i needed a bigger alt to cope with the extra stuff i was running.
stu.
