      I was running 6psi with a 5inch pulley,, for every 1/4 of an inch in diameter smaller psi should go up 2-3psi,

      I am running a 4.5 inch pulley.. THat should be good for 10-12psi easy..

      I did add a pulley just below the supercharger to try and get more wrap on the supercharger pulley..

      In the past i had heard the belt slipping, not something ive heard since i added the extra pulley
