    Hey guys I have a 2.90 Metco pulley nib. I plan on installing this very soon. Will I need an AUX Idler, or will I be ok without it? I also have a 100mm idler pulley that I can install. So do I need a new belt? Or will the stocker be ok? Car has jlt ria, pypes x-pipe w/ metallic cats, Borla stinger, and currently tuned. Car makes 421hp currently and hoping to break the 475 hp mark after pulley install and retune. Thanks for your time.

    Yeah you're going to need:

    1.) Auxiliary Idler (100mm is fine and will lower belt slip better than a 90mm would)
    2.) New Belt ('Gates' or 'Gatorback' in the size of 75.50 inches I believe)
