CA Lightweight Crank Pulley
I'm looking to sell the cobalt addiction lightweight crank pulley. I've had it on the car for approximately 50 miles but I plan on going turbo so I have no need for an overdrive pulley. It has the black finish and, as previously stated, is overdrive. The pulley will also come with the upgraded crank bolt that GM recommends.
CA pic/description:

perfect for supercharged vehicles as it will net just about 1# more of boost and also take up some belt slack you may have from running a smaller pulley. Perfect for those running GM stage 2 kits and wanting alittle more boost. Also perfect for those wanting to run more boost without having to machine the supercharger snout which is required on some smaller pulleys. Also perfect for those running large stereo systems needing alittle more output from the alternator at idle , will help fix the dimming light syndrome.
Update: Price dropped to $135 shipped (upgraded crank bolt included). I need money to put towards the vette!
They retail for $200 plus the price of the crank bolt

The diameter. Overdrive will give you about 1/2#-1# of boost on a supercharged car whereas an underdrive is more common for turbo'd cars. CA says that this pulley fixes the electrical issues with the dimming lights as well (turns the alternator faster) but I didn't have it on the car long enough to test that out. It definitely nets boost and revs up much faster, though.
