race crank pulley?

is the pulley really worth the money?

If your talking about the RJC verions there are two, the stock replacement type, and the none-fan race version.

I went with the none-fan version (I have a F/M), and I had to add a little accleration enrichment, due to the reduced weight. It wasn't much, but it's one of those little things that do add up, IMO.
If your talking about the old ATR race underdrive pulley, don't waste your money. Yea sure it buys you a few horsepower, but is hell on the accessories. I killed multiple alternators, a water pump and a power steering pump. On yea, the air conditioning sucked. I currently have the RJC pieces, which are sweet. HTH
