Description
MIA's Description
This pulley features lightweight pockets to reduce reciprocating mass and a guard to prevent belt wandering during operation. The running diameter is engraved on each pulley. A general rule of thumb suggests that every .125-inch change in pulley size equates to approximately 1 psi of additional boost.
