We had one on a 440 with a TVS2300 and just the single 6 rib only making 10 psi. I didn't take long before it would slip every once in a while. It was like a quick loss of power and it would come right back fast. The only way I can think to figure it out would be to have a boost gauge or monitor the map reading while it does it. If you lose pressure at that moment you have found it. You probably want to start on an 8 rib setup anyways above 7 pounds, but others might know better what they limit is with this setup. But, it is driving everything with that one skinny belt.
