Do you do the 3.4 inch pulley 10 psi, in the 6 ribbed belt set up. Or can the 8 ribbed 3.4 inch pulley go on with the 6 ribbed standard pulley set up?

If you wish to run 8 rib pulley you would require single 8 rib serpentine belt conversion pulleys with 5% over drive race balancer. Comments 0 comments Please sign in to leave a comment.
