vortech owners help please I just purchased a v9 aftercooled kit. It has the g-trim head unit. Right now it has the stock pulley on it which is the 8 rib one. I believe it is the 3.125 pulley which is good for 9lbs correct? Also have a 2.75 pulley for the kit. What kind of boost would the 2.75 pulley provide me with the kit? Mods are in sig. I have longtubes, no cats, and the loudmouth. I have heard that a free flowing exhaust like this would bring down the pounds of boost a little is this true? Have done some searching but have not really found the answer that I am looking for. Also any guesses as to what I might dyno with the stock pulley versus the 2.75 pulley? Thanks ahead of time for any input. It is greatly appreciated as I am a newbie to the whole blown game.

Stock would be in the 400rwhp-420. With the 2.75" you should be in the 480Range it really depends a lot on the tune though, through the auto I wouldn' be dissapointed with 460 with the 2.75" It will roll real good though so don't dought that. Good luck.
