Belt is not rubbing on anything.
I tried to loosen the belt up a bit just for the heck of it, but my tensioner pulley is giving me issues. I have to loosen the tensioner pulley in order to drive the tension bolt in, however it does not drive in nearly as far as what kraftwerks calls for. My tensioner bolt is currently pretty much all the way out, but the belt is still tight. Do I need to play around with sliding the pulley closer to the left side and then tightening it down? The belt seems to come too tight when I tighten the pulley back down, so I end up backing the tension screw back out.. They just kind of seem to be fighting each other. I'm going to try and loosen the pulley back up, slide it far left and tighten the tension bolt in to ~50 hz, because I know when I tighten the pulley back up now it is going to pull my belt even tighter, hopefully to the normal range-ish.
There is also no specified torque for this pulley in any revision of the install manual, not that I would be able to get a socket on the back of it while it's mounted anyway. Only way to access it currently is by removing the upper SC bracket and using an angled 14mm wrench to loosen it.
Has anyone had similar issues or possibly knows a better process to tension this? Or any other reason as to why my kit is currently sounding the way it does? I've already contacted Kraftwerks, still waiting for a response.

if I remember correctly when I had this kit, yes you have to loosen the pulley as well as the tension screw.
if you just try to loosen the tensioning screw nothing will move. loosen the pulley first and then loosen the tension screw. The reason why your belt is whining is because it's too tight.
this is the main reason why this kit was such a big pain in the ass. The ONLY way to get a socket behind on the pulley is to not use a socket. Do yourself a favor and buy a set of ratcheting wrenches and fit the end of it on there and loosen it that way. Otherwise you will have to dismount the entire thing.
I've had this kit for almost 3 years and i'm not surprised kraftwerks still don't listen to their customers and that they need to implement an auto tensioner.
no matter how many times you tighten or loosen it, you will ALWAYS be constantly adjusting it due to changing weather. Colder weather will make the belt extra tight so you'll have to loosen it. Hotter weather will make the belt too loose so you'll have to tighten it.
The shittiest part about it is, if you don't catch the belt issue in time, your pulley bearings will go to shit causing your pulley to wobble. Once your pulleys start to wobble your donezo because the belt will have irregular wear causing it to snap.
good luck with your kw kit.
edit: ps. if you let your belt on too tight for too long, you'll snap the bolt that holds the gear adapter to mount on the crank shaft lol. There are also numerous reports of the input shaft breaking as well. Lastly, if you do all of those steps and loosen the belt up and the sc is still whining, you're double donezo. That typically means bad supercharger bearing, which means you having to send the unit into kraftwerks for them to send it to wherever the place is in europe for who knows how long of a turn around time.
