i have been kind of slacking around here, huh.
yerv[g35] - I LOVE MINE!
1. an underdrive crank pulley underdrives your a/c and alternator (i think those are the 2), thus freeing up horse power ESPECIALLY at lower rpms. it's about 1/2 - 2/3 the size of the stock pulley and MUCH lighter. i haven't had any problems with my a/c, electrical, or power steering. my car is running fine.
2. YES, it's a noticeable difference and a GREAT mod. most of the people who bash the underdrive pulley don't even have one. they'll say it only adds 4-5 hp but that's not what matters. the car drives much better with the extra ponies freed up.
3. get an Unorthodox Racing crank pulley. my original one was a cheapy off of eBay. i ditched it quick for a known quality part. you don't have to buy the whole set if you don't want to. the other pulleys are mainly for decoration.
4. you can put up to a 600W after market system in and shouldn't have any problems. get a 1 farad capacitor justy in case.
5. you'll need 2 new belts.
