I have heard from many people that most gains have been seen the best from the ASP pulley.. many sponsers have them for sale! check them out! if you have an A4 try the overdrive alterntor pulley and if you are an M6 get the underdrive alternator pulley! or leave it stock for less money and just get he crank pulley only! haha.. Make sure to get all the belts and be safe with an ARP reusable bolt.. check www.futralmotorsports.com they have it all listed out! good luck

i recomend going with tsp. i just got a power bond pulley (25%)from them and it is a very nice piece, plus its cheaper and looks better than asp.

20 - 30 hp with no loss of cooling or charging is probably an absolute best possible senario. Plan on 9-12 hp, and you won't be disapointed.

I bought the March set. I haven't installed it yet though, so I can't speak from experiance.

i like the idea of 10rwhp from a pulley swap but ive heard of vibration issues and dampning issues.... so, im still without one.....

anyone else have any info on that?

I have the powerbond/SLP pulley and it's a very nice piece. It's not supposed to throw belts, wobble or cause KR like the ASP and some of the others have. It is steel and stronger than other aftermarket pulleys, yet lighter than stock. Typical gains seem to be around 8-12rwhp. Also I wouldn't buy the alternator pulley. IMHO, it's a waste of money and will just take away some of your gains and is not necessary. I have NO problems with cooling, dimming lights, etc. It may run a HAIR warmer, but that's even debateable. I've kept a close eye on engine temps, light dimming, etc. and for the life of me can't tell a significant difference. As you can tell I'd highly recommend this pulley, and no I don't work for powerbond or SLP lol.

yea just do searches on ASP pulleys and the powerbond... and base your choice on feedback from the 2.. Thats pretty much what i do for every mod.. get a few different choices then see what other people think and their experiences with them.. good luck
