Just like the tittle says, I'm looking for a 4" inch pulley for the F1R please.
My calculations have me just about maxing out the impeller speed with the 4" and 7400rpm and I'm going to waste gate/ boost controller it to keep psi where I want it.
EDIT: looking for a 12 rib and a belt to fit as well.
