...folks wanna bigger crank pulley?...

Sounds like an ad in the back of some sleezey magazine!




And before you ask....I was just reading the articles!

It does work to a point at the OEM settings/Factory parts. I went with a smaller pulley on the supercharger on my Pontiac SSEi and it did help some. And at a Hotrod point my Pro-street 66 Chevy II w/BBC L88 with a BDS 671 Supercharger, between my buddy who had the same charger on a SBC we could switch our pulleys around and have combo's of 13%, 6% under-driven. 1to1. and 6%, 13% over driven. I had my mainly at 6% under and it ran cool and no detention, But at 6% and 13% over it had detention more and ran 10 to 20 degrees hotter. I did cure some of that with a MSD 6AL and a different degreed Comp Cam and re-jetted my Dual Holley 780 carbs.

Mostly I'd like a shiny cool billet crank pulley, but yeah, another lb of boost wouldn't hurt my feelings none either...
