Those of you running S-trims!

What rib pulleys are you guys running on your s-trims? Does the stock pulley slip at 8-10 pounds of boost? I'm thinking about upgrading to the 10 rib setup. But won't if its not necessary. Just curious if any of you guys expierence slipping issues?

Got a 6 rib running 8lbs on an S-trim on my Cobra. 10,000 trouble free supercharged miles. No belt slip, no noise...nothing. That is all you will need if you have the proper tensioners and pullies. I would suggest buying a new kit, and avoid a used one.

SQ here, with the stock 8rib pulley's i saw 10psi....then went to 10 rib and a 2.95 blower pulley and see 15psi. No slipping here on either setups.

No slip here either. As stated in the first response, do it right and you wont have slippage.
