    3.0 pulley on 6rib.....

    Anyone running a 3.0 pulley on a 6rib? Are you experiencing belt slip?

    The smallest 6 rib drive pulley we have ever been able to run with any success was a 3.20 on a D1SC. Any smaller than taht and we saw either too much boost or massive belt slip.

    Injected65, thanks for the reply. How much of a boost increase might I see going from a 3.4 to a 3.2?

    Hi there,
    If you're looking for an increase in boost why not increase your crank pulley size. The stk. GT crank pulley is 6.50" and if you get a 6.75" or 7" you'll see the increase in boost pressure you're looking for.

    I saw an approximate 3-4# increase by going from a 3.80 to a 3.50 on a D1SC.
    So you can figure your gains would be right around here.

    good luck

    Michael Plummer, Yeah I'm looking to get an overdrive crank pulley now, but no one makes a 6-rib. I have found a couple of places that make them in 8-rib, but one place told it would work and the other said the belt would walk on the pulley and shred.

    paluka21, thanks.

    Hi there,
    Auto Specialites will make a 6 rib crank pulley for the SN95 Mustang. Try calling them for pricing. I hope this helps.
