I noticed you supercharged your 190e 2.3. I am wanting to do this to my 190e 3.0. I have an Eaton m90 but it has from what i believe a too small of a pulley. Its about 3.125 inches that on a supercoupe with its 7 inch crank pulley does about 12-14psi. I want to run 8 for now. What size of pulley should i get?
