the snout machine tool came with no instructions, so this is how I did it: first you make a mark at the end of where your pulley is so you know how far to machine to, second you have to take the snout off the supercharger. if you have a 1" phenolic spacer, or an intercooler, you don't have to take the snout all the way off, the two bolts by the alternator have enough access so you can loosen them up, but the bottom one won't come out, not enough clearance, but you can still get the snout machined. then you need to render the mps hub unable to spin, I used an allen wrench in the coupler with pressure applied the direction you want to spin the hub. then you put the round part of the snout machine tool onto the hub, also have to take the snout plug out of the end by the mps hub before you install the round part of the tool. once you have the round part on there tight, you can install the stud that the spring goes on and the cutting object through the square hole, when those two items are in, you take the washers, spring and nut and tighten it so it's hand tight. then take your drill and spin away. if you spin it slow enough it will be shiny. when you see the shavings stop falling, tighten the nut again and keep going until you hit the mark you initially.
