Do you know if it's possible to adjust the tension of the short belt on the supercharger side without taking the whole supercharger out? I have a hard time seeing wrench size needed because it's kind of tight there

Yes from underneath. Two long 3/8 extensions, a wobble and a 14mm shallow socket. The bolt on the idler itself should be a 19mm wrench. Back it off just a little and then go beneath and increase the tension a little. Tighten the pulley back up.

Keep an eye on the pulley as the adjuster setup puts all the tension on the inside and the pulley can ride askew, potentially causing belt to ride off the rib or put lateral pressure on the bearings. I used a larger, thicker washer behind that 19mm nut so it will sit true when tightened back up.

Don't try and tighten the tensioner from below too much at once. It is really easy to over tighten. Better doing it a couple times instead of getting aggressive with it from the start.
