Alternator Pulley

I was just wondering if this would help horsepower or acceleration at all? I already have the other Unorthadox pullies but I'm missing the alternator one. It says that it's 10% bigger but it's cnc machined out of Billet aluminium. I asked the guy selling them and he said that it's lighter than the stock one on an RX-8. Plus it kinda looks cool, but let me know if yall think it's worth it.

Thanks,
Jamie
