,i was woundering if anybody else has this problem,i have the RK Sport underdrive pulley for my 2003 ECOTEC and i'm getting the GM Supercharger and i need to know the belt size(s) of the factory, RK sport underdrive belt, GM supercharger= so i can figure out what size belt i'll need, i have AC ,any help would be great,thanks Gary
if at first you don't succeed,you should probably give up
Underdrive crank pulley + supercharger = bad idea.
14.330 @ 96.37mph
that sucks,good thing i kept my oem pulley,so what happens anyways?
if at first you don't succeed,you should probably give up
forgot that i took my dumba$$ pill this mourning i answered my question after i posted,but thanks lil black two four for getting me thinking,i would have realized my mistake to late,at about the time my supercharger went spinning through my hood,thanks man

they will possibly be making a light weight crank and alt pulley for the Eco in stock size. you'll wanna get in on that. it'll be a GP. they have one going on now for the LD9 but i believe the guy doing it is looking into doing the same for the Eco.
he should have the eco pulley in the next couple days
and the s/c would spin slower with the smaller pulley , and drop the amount of boost
that is if you could get a belt to fit , which will be hard since the s/c belt is a double sided belt
