Went down to a 111 for the 3.0 pulley, and its still slipping....what size belts are you 3.0 guys using?

 

Is that slipping with a gatorback? The gatorback cured mine from slipping. Where does your belt tensioner sit in it's range of travel? Is it in the middle of the range or is there just barely any travel?

 

tensioner is in the middle...and its a gates belt.

 

No help to your question. Sorry. How do you know when your belt is slipping?

 

Will that Katech tensioner work with your setup??

 

I might have a solution to your problem in a couple of weeks, been testing an idea, I'll let you know when I figure it out

 

You'll know it's slipping because the boost reading on your guage will vary.... my needle bounced when it was at peak boost. I also found black "dust" around my pulleys that was from the belt. The gatorback belt stopped it from slipping in my case.
