You can always media blast your stockers and powdercoat them if they are ugly... Other than that its accessory pulleys.

removing accesories that aren't needed seems to be the BEST answer.

Yeah, I can't find one on their website. I really need a crank pulley right now. Neither ATI or Fluidampr list them on their site.

It's a rubber dampner on the crank pulley intended to help make engine internals last longer due to vibrations caused by the motor.
You can run a solid aluminum pulley but you will likely find more metal shavings in your oil pan in the future & loads of premature wear on engine internals like valves, pistons etc.
I read a great article about the wear years ago when someone installed an aluminum crank pulley on their Sentra R - the pics of the engine ripped apart after several thousand miles was pretty amazing.
I'm not sure if the page still exists, I'm too lazy & too old to try to search right now.

There's really no real need to run a lightened underdrive pulley on a street car.
As was mentioned above, do things to remove weight from the drivetrain itself + run lighter weight rims.
You've heard of unsprung weight right?
Install a C/F driveshaft which is a ~30lb weight savings over stock, lightened f/w, shimless (shim under buckets)
Make what you have more effecient, then do things like strip the interior if you want to go deaf, tear out the A/C so you can burn up & tear out the power steering so it will be as uncomfortable as possible to drive.

Speaking of Sentras makes me think of the magazine that "made" a kid's Sentra a 10 second car. Good stuff. :twisted:
