You're joking right? Underdriven alternators don't perform very well if you have any extra electronics (sound system, nav., piggyback, ect...). That can cause your battery to lose charge over time which is not a good thing. The fix, get a better alternator. Also, underdriven water pumps can cause over heating, especially when it's a turbocharged application. The fix, get a more efficient radiator. Your air conditioning won't work quite as well as it used to, but that's usually negligable.
