How bad is the 6-rib I searched and found a little bit of information on this, but wanted a little bit more. Exactly how bad is the 6-rib setup on a car running about 6-7 lbs. of boost? I know its really bad when you get into bigger boost numbers, but is it horrible at low boost also? Another question is about how much does it cost to switch to the 8-rib system? Thanks in advance.

If you don't slip on a lo-boost 6-8# setup with a 6-rib, an 8-rib won't do a thing for you.
Switch to 8-rib is: 1 wider belt, 1 blower pulley, 1 idler pulley, 1 crank pulley, plus anything else on that belt. Figure $400 in a pulley/belt swap, maybe $500.

I too am trying to figure this out...Im going to be running a stock motor with about 8lbs of intercooled boost...Is the 8-rib setup absolutely necessary? My goal is 500rwhp DD.
To answer the thread starter...I believe you also have to pin the crank when using an the crank pulley for a 8rib set up. I may be wrong tho.

This kit includes all the other parts that are required for the conversion, plus links to the harmonic balancer and the crank pinning kit that are required. Bob

Pinning the crank puts a metal pin between the crankshaft and the harmonic balancer to help prevent the balancer from turning/slipping on the crankshaft. The supcharger puts extra load and tension on the balancer. This extra load can sometimes cause the balancer to slip when it gets too great. If the balancer slips too much it can loosen the balancer bolt and cause the balancer to come off.
