What are you guys doing about belt slippage at high rpm? I already have 8 ribbed pulleys. I also just replaced the tensioner and belt. If I get a belt any shorter I won’t be able to put it on.
 
sorry to hear you still have slip with 8 rib.
I am in the end stage of 8 rib upgrade, all thats left is a tune with Marty. I drove the car about 30 miles easy after the upgrade and before the tune, and there is a small amount of belt dust present. not much.
I have a vortech v7 supercharger, a 10% od balancer and a 2.75 inch supercharger pulley.
through many conversations on this board, it seems all this is left is a sturdier tensioner. however, 1) it would require mods to somehow attach it to the engine cover 2) these tensioners arent cheap, 3) cant find one online.
this has left me dependent on the oem tensioner, and something better is probably my next improvement - just not sure how to proceed.

the Thump RRR single bolt tensioner would work, however, I think those have been discontinued… anyone got one for sale?

Many on this site will disagree with me, but this (in my opinion) is the only way I would install a centri

8 rib setup is a must
3 bolt timing cover
ThumpRRR tensioner
Mechanical vacuum pump (independent PCV system)
 
i dont disagree!
where do you find a 3 bolt timing cover ?
does it need lots of modifications to “fit” a MM ?
