You're right. Would you be so kind as to add that option to the poll?

I installed a 10% myself but kind of wish I would have went stock. Need to go to a OD for the alt. I think the 10% under is accounting a bit for my over heating issues due to the water pump spinning a bit slower. Now that I have dropped to one fan and less air flowing through the radiator.

Someone needs to make a pulley that increases power by 25%. THAT would be big!

Now I'm thinking I might go with the SLP pulley or maybe even the March (steel)...I dunno

I would say 10% for your race only. Most people are 25% for reliability and charging issues. The HP gain from the 15% differenece will not make up for the undercharding of the alternator.

The 10% pulleys charge MORE than the 25%, you're thinking is backwards, the 25% ones are smaller.

Powerbond 25% UD pulley here. You won't have any problems as long as you don't have a big stereo system.

yeah SLP copies everything and marks it up.

*Pulley = powerbond marked up
*Rocker Arms = Harland Sharp anodized silver instead of orange and they charge $500 instead of $330.
*Handheld tuner = Diablosport marked up
*CNC'd heads = AFR marked up

The list goes on... The only thing SLP did right was the Firehawk & SS. They should've disappeared otherwise. *poof*
