[QUOTE="by9468840, post: 12967199, member: 146670"] Nope. 575 comes with 85 and 625 just adds a cai and a new tune to it. 675 comes with 80mm and cai. I'm getting the 575/85 with 82 and 79 pulleys from vmp and their tune. I'm not a fan of cai and the whine it makes. So I will stick to the air box. I am just a little worried if 79 would be too much for the stock engine. I am looking for some feedback on dyno numbers and drivability. If 79 adds just 15-20 rwhp more and similar torque maybe it is not worth it. As far as I know ever psi added exponentially contributes to heat soak.it would be nice hear some feedback from daily 79mm drivers. [/QUOTE]
