So I've been wanting to rebuild the top end of my 3800sc, but before I pull the supercharger off, I need to decide on how to route my belt. I think I've got it now though. I'm going to be running an electric waterpump, no A/C. So I figure its not really worth having 2 belts. Here is what I think I'm going to run with.

The alternator isn't fully mounted yet, and I flipped the idler bracket and drilled it out just bigger than 3/8". I picked up another pensioner pulley to replace the idler with as it's about an inch smaller. I figure this way should work. The alternator will have the least wrap, and even then, its almost half.

So what do you guys think? Don't hold back, I can take it

Generally a bad idea to go with 1 belt if you don't have to, the supercharger and the alternator are both high resistance devices when they are under load, but looks like that should work fine.
