I changed pulley from 3.60 stock Vortech pulley to the Reichard Racing ultra-grip which is 3.40 in size. I would think actually with that diameter it would speed it up just a tad since stock is 3.60 and next size down for me would have been 3.4 then 3.3 .... I dunno kinda wierd. I guess it's because of the lower idle point?
