So I'm stepping it up a notch, need more powwa! I'm not sure how long I'm going to be driving my current vehicle, so not sure if I want to dump an alt in it. What would be better to run around ~2kw daily... HO alt w/stock batt OR just 1 drycell batt w/stock alt? Do they have alts with a general size and I can just buy a bracket to swap from one vehicle to another, like from one GM to another GM vehicle?
Btw I currently have have stock 105a delco alt w/ interstate wet batt in a 98 grand prix
To make a solid electrical system you really need both, alternator and battery. I would say hold off on the big system till you get the new car.
Alternators in most cases will not swap. Especially with newer vehicles where the BCM controls the electronics. It is not the physical mounting that is the problem its the electronic interface with the vehicle.
I've ran both a DX1500.1 (same board as the SAZ-1500) and an RD1750.1 on stock electricals with no problems so i think you'd be fine with 2 dry cells with that much power ;) but thats just if you ask me
