RE: pulley size

hell if i knew that. whats the purpose of underdriving the accessorys if the crank pulley is spinning faster?

would seem to me that they would still spin at the same speed as the stockers.

and yes, my pulley is bolted with allen heads.

Some technical BS about ratios or some crap? Don't feel bad tho, I just was informed that BAP and MAP sensors are exactly the same..... go figure!

the crank pully isn't spinning faster, it's moving less belt...
