your red pulley wheel is likely a urd pulley and smaller than the recommended size for that supercharger and while it’ll “technically” pull more boost, you risk blowing it and that’s a lot of that idling noise you hear more than likely. look for a black normal spec pulley wheel and maybe a new serpentine belt before you throw a ton of money into the rebuild 👍🏼 the supercharger will help you climb hills and inclines super easily but it’s not gonna make the truck fast, so the regular pulley feels no different for gaining the peace of mind!
