i'm sure it can be done... although you'll then have to run either another belt or a longer belt, to me, it wouldn't be worth it with all the extra drain on your engine. What do you need it for? A system? Sorry, but to me, there just isn't enough room in the tc for a system large enough to warrant 2 alternators. Maybe i'm wrong, but do you really need that much boom?
Have you researched your design goals to the point where you believe you really need them or are you just speculating? Not dissing you buddy, just not something many people would ever have a real need for
It would be easier to install a higher output alternator than add a second one.
A second battery is seldom needed for any resonable system, all it does in let you play longer with the engine off then creates a bigger load on the alt when recharging.
Tell us your reasons and maybe we can help you with the right answer.
