Yes,
I ran a 6 rib serpentine belt,w/no slippage problems,but I was only getting 8-9 lbs of boost pressure.
B&M has been selling 10 rib serpentine belts & pulley systems, but those slip also.
My friends 10 rib setup slipped on his SBC w/a B&M (roots type) 162 blower putting out 10 lbs of boost pressure.
It depends on what supercharger you have as to how much slippage @ what psi of boost pressure.
Somewhere approx between 12 - 16,18ish psi is tops on a 8 or 10 rib serpentine set-up for a centrifugal type blower..
The gilmer (SP) cog belt drives are the best.
They also cost the most.
