At what pulley size are you guys noticing belt slip with the standard 6rib on the tvs 1900? I'm debating if I'd rather go with a tvs 2300 and bigger pulley, or get the 1900 and pony up for a 8 rib. On my current 112 I do get belt slip with the standard 6 rib and HD tensioner and 3.0 pulley

 

I am 8rib 2300, on that note I have never had belt slip so I can't really say. It's more about boost level then pulley size.

 

I had a 2.7 rip cut pulley on mine with no meaningful belt slip. it had slip when i let off etc... but not much that I could tell WOT.

 

I can really hear it chirp/slip after letting off, not as much when I get on it.

 

This is normal, and nothing to be worried about. Unless it's throwing the belt.

If that's the case, it's usually an issue with belt alignment, belt length, or tensioner problem.

 

I was throwing belts left and right until I got the HD tensioner, that solves a lot of it. I'm just wondering if the TVS blowers are any different especially because on the newer 2014+ trucks there is not HD tensior for them that I'm aware of.
