Both Pulleys or Just one??

Hey I wanna get the ASP pulley but I'm not sure if I should get both the crank and alternator or just the crank. Any suggestions???

If you're not running a stereo or too many accessories, you'll be fine pulley only

Not sure if there's any true "power" gain but you take away rotating mass and slow your accessory pullies in relation to crank rotation. All in all it should be good for a tenth in the 1/4 due to quicker acceleration!

Uh, no. Smaller pulley = smaller belt. When you get the pulley the instructions will tell you what to get. And for an M6 car just the crank pulley will suffice. Some A4's need the overdrive alt pulley for charging the system.

Typically the manual cars can just use the crank pulley. Some autos can get away with just the crank pulley (I have this setup on both cars), while other autos may need the over drive alt. pulley. I will probably be purchasing the over drive alt. pulley for our Camaro SS for safe's sake.

I agree, the alt pulley is not really needed. I have two amps right now one is 420 watts RMS and the other is 500 watts RMS and I didn't need the pulley.
