brad, that is why i am prolly not going to mess with the alt pulley. b.c the lights will dim... i am just going to stick with the stock one. plus it is not worth $200 for 2-5 HP

Because of the extra alt strain i'm pretty oppsed to them, save a race car.

Just FYI, you are buying a lot more than a pulley, the Dampener is responsible for absorbing all of the harmonics tranmitted to the crankshaft everytime a cylinder fires. Think about it, at 6000 rpms your crank is absorbing 24000 cylinders firing a min, thats 400 cylinders a sec. This is why controlling harmonics (vibration) was my primary objective and reducing accesory drive losses my secondary objective when i decided to replace my harmonic dampener/pulley.

I'm for it. For 10 rwhp or 1/10th at the track, it's a worthwhile mod, every little bit counts. FWIW I didn't have any charging or dimming problems on my M6, with the ASP crank underdrive pulley, but the M6s idle a bit higher than the A4s...
