Haha, well I would doubt maxing out #50 if fellows run similar, or smaller pulley's set up than mine on 42.5'er.
Not sure what the pulley on the alternator is, though. It's an early production car, so might be anything they had then, still factory.

I guess I just need to fine-tune my timing and trims at WOT to tune out KR on the second gear. (My trims are most of the time in the -3 +3 range, so it's getting there.)

Right now, first gear pulls from a stop, it runs hard without knock, my issue is mainly when driving above 70-80kph, whenever I get on the gas, not even wot, I see some KR spikes, even saw, I think it was 4.9* at one point, never too sure, I barely if ever drive that car faster than 80-100, since work only requires me to drive in its knock-free zone.

I've got, hmm, 1-2 years old AL104's with maybe, max 5 or 8k KM, they're gapped at 0.050. They should technically be enough for a 3.2 Gen V - Headers - XP car, right ?
