Just ran at Roebling Road Raceway yesterday, and had no belt issues!! Spacing the lower pulley out fixed my issue!
Just to close the loop here in case someone finds this thread in the future, I used 1/4” grade 8 washers (they are the gold washers, it’s just what I had I doubt you actually need...
I will have to check the calibration. It was very challenging getting the tools on the pulleys in the same grooves for sure.
What did you do to fix your alignment?
Since I cannot figure out how to post the video, here are screenshots at RPM at the moment the belt pops over the top of the front of the lower pulley. Again, these are at RPM, it doesn’t look like this at idle or when it is not running.
Everything is new, or at the most on the car for only a year. I have 1mm spacers for the alternator pulley, but that would push the pulley the wrong way. I almost filed down in the alternator pulley to get it to move towards the engine, but I was afraid I would end up filing it crooked and jack...
I am back trying to figure out my belt issue. I made some short videos, but I cannot get them to post, so I will do my best to explain what I am seeing. When I rev the engine, I see the belt ride up onto and over the front of the lower pulley, and it immediately returns to be centered on the...
Ok, so no damage on any of the pulleys. I checked again with the laser and they are all aligned.
My current next attempt is to either cut down one of the damaged belts to maybe 6 ribs and re-install, or just install the belt with the undamaged side out and try to see with the fresh edge what...
Interesting, I have a PA performance alternator I installed as it came from them- ie I did not install any spacers. Maybe I need to look harder at the alternator?
I am continuing to tear up supercharger belts- IE: shred one rib off of the belt, and I am looking for input on what the cause may be. Here is what I have done/found so far:
Going back to the beginning of this issue was July of 2021 when I got home from the Dyno. I drove her home from the dyno...
I see everyone is recommending to fire it up, but I primed mine before starting when it sat for a couple years. Good to know it should have been fine either way.
