8-rib pulley system with blower

[PowerCobra98]

Has anyone upgraded their pulleys from the standard 6-rib configuration to an 8-rib configuration? I'm just wondering that if you were experiencing belt slippage with a 6-rib if the 8-rib solved your problem. I am currently not slipping but was thinking about converting as a precautionary measure...

I havent yet, but I will in the very near future.

morpheus performance (www.morpheusperformance.com) offers 8 rib pulley setups cheaper than most competitors.

Although we have different platforms, all 6-rib pulley systems WILL eventually experience belt slip at the higher rpm's with increased boost. I was getting slippage at 5200+rpm with the six rib. I upgraded to the 8-rib and ATI Super Damper and have had no slippage at all.

Some of the guys with 600+rwhp who do a lot of drag time at the track have experienced some slippage even with the 8-rib setup.

I have an 8 rib setup with no noticable belt slippage, thanks to a nice little tensioner I picked up.
