we stock the powerbond pullies, and have a very competitive price, the belts you can get from any local auto store. SLP has the part numbers listed on their website that you can take to auto zone, napa or wherever and have the number cross referenced.

From what I understand if you dont have an aftermarket radio system then just the crank is needed. However you can get the alt pulley also to keep the volts steady.

They "underdrive" the acessories thus producing more power (or taking away less if you care to look at it that way). You can see a solid 10hp gain and .1 reduction at the track.

I got my SLP pulley from New Era Performance. They had the best price when I was looking around.

Check SDParts.com. They are a sponsor here and run specials from time to time that are a deal. I got the last one they did and I got the Pulley, belts and bolt for $199.

well I'll be gettin a pulley soon here for the long run, but 2 weeks ago at the track, my buddy and I raced against each other AT LEAST 5 times. All he has over me is a pulley. We had the exact same times, the exact miles per hour, just slightly different 60ft.'s. (13.1x @ 109) Then we got our cars dynoed at the same time a week ago. It was at the Lsx shootout on a dynojet, one 4th gear pull for $30. I had 330rwhp, he had 335rwhp. Go figure...
