How can i make some more boost i want like 2-3 psi more. I currently have a 2.75 inch blower pulley and an f-150 crank pulley on my single belt. Also i have a power pipe. Is the 8" crank pulley larger than the f-150? Would a cam change make more boost if you went from a very large cam to a smaller cam? I am currently getting 7-8 psi at 6k and would like a solid 10psi. I used to make 13 psi but now with my victor jr heads and ported holley intake it fell to 7-8. Thanks for the help if the famed 8" crank pulley is smaller than the f-150 i will purchase one, which water pump pulley is used to clear it?
