So I have a L33 from a 2008 silverado and a Magna MP122 supercharger and a mechanical tensioner installed on my long travel car. Last winter I installed electric power steering. So I bought a alternator bracket from Summit and installed it down below and rerouted the belt like the second photo. After losing the belt a few times, we noticed the alternator was moving so we figured the belt slack was making it fall off. I then moved it back up to the top rerouted the belt again in the manner of the third pic and we are still losing the belt. I have a bunch of things and was wondering if anyone has any solutions to this problem. It would be great to have a 8 rib system. but there are nothing available to change the snout on the MP122 to the car type system. Or is there anywere to get just the pulleys in a 8 rib belt. Thanks Chris


Original setup before I removed power steering pump!

After steering pump removed. Alternator bracket was moving.

Moved alternator back up top and still losing belts.

 

It has to be mis-aligned, and third picture looks like the belt is in contact with itself coming back down from the blower.

Just using a manual tensioner for this setup?

Is it throwing belts in full boost, random or as soon as you start it ?

 

Looks like you need a second idler pulley, the belt to too close to the one that is there.
