What is this supercharger tensioner setup? It doesn’t look like what I usually see in pictures from the archives:

don't know above setup....
Some engine swaps have "deleted" ac etc and use parts from Dorman and other 3rd party parts to have a pulley in same spot so rest of belt path/map still works.
Others have made "DIY" pulley and whatever mounting for same reason. They may even used an extra tensioner.
If a pulley has bad bearings etc, Might find a new pulley thru Dorman and others. Or just replace the bearing with some pulleys.
Example: Like many OE setups expect Hydro PS pump and Fiero doesn't need that but engine need a pulley in same spot or often major problem to rework the belt loops if can rework this at all. Most engines can't just use a small belt w/o ac compressor like 87+ Dukes covered in my Cave, Serpent Belt and other places.

Supercharger belt setup is mostly the same with different years/models. With 2 idlers and 1 tensioner. However in the last picture that looks to be a tensioner with a shorter "swingarm", same job but shorter range. If that is stock it should work.
Accessoiry belt setup is a whole different story. With PS/AC deleted and alternator relocated there are many different setups possible.

Thanks, I was wondering what to do if I need to replace the tensioner. Belt that was on it was at the limit of the tensioner and not tight enough and squealing, I’m trying different belts to see if something works better. Part number might be stamped on it if I need to replace it?

Ya I was wondering if a certain model or 2 with the 3800sc had this tensioner setup, curious if someone like Darth Fiero might know and chime in. Or if this was a custom setup some 3800sc people opted for years ago?

I deleted the PS and AC and moved my alternator where the PS was. Also put errthang on one belt, took a few tries to find the right size belt. There are charts online that show the total length, I think the one I used was on gates website. Search for serpentine belt size chart and youll eventually find what yer lookin fer.
