where is the best place to find an upgraded blower pully, I remember seeing them around before, but now cant seem to find them. sorry for a dumb post....and yes, I did a few searches.
does anybody know what %overdrive the racer walsh pully is? it claims to raise boost to 10-15 psi, and add 25-30 HP and 40-45 ft/lbs. and it comes with a belt.
