I have a 1994 M6 Trans Am and I'm looking into buying pulleys. I've heard of the voltage drop but I think I'll live with it. Anyway I know there are alternator and underdrive pulleys, I've also heard of the crank pulley but isn't that the same as the underdrive? I am running an amp and subs but since my car is an M6 I don't think I need the alternator pulley. Can you guys inform me on the whole pulley idea? Also what pulleys and brands do you guys reccomend for me to get?

 

their not worth it...barely any gains...save yer money

 

agreed....SPECIALLY since you have a system.

for the 1hp and 5-7#s of torque...not worth killing your battery.

 

I think a mail order PCM tune will be a little more in price, but net better gains, and will probably take alot less effort to install.

 

If you get them, I would get the alternator pulley if you're running a system. I've never had a problem killing my battery with mine.
