last bolt on
last bolt on Well, I won't be putting an electric water pump on my car, so an underdrive pulley is my last bolt-on. I have an A4, will I have charging issues? Or should I buy the overdrive alternator pulley? Will the stock belts work with an u/d crank & o/d Alt pulley setup? How much hp loss will there be with the o/d Alt pulley? Should I just get the u/d crank pulley?
charging issues wont be a problem IF you dont ahve anymore than a stock or near stock stereo.
these pulleys are smaller, so obviously you need shorter belts, tsp has the pullies and belts.

if you order the asp pulley they should give the part # of the cable you will need to pick up...you could go ahead and pick up the asp alt pulley that will go with the underdrive pulley... 
Just get the underdrive pulley and don't waste your time with the alternator one. I have all of the bolt-ons with just the underdrive pulley, and have never had a charging issue on either of my cars.
