I have an sn-92 with a 3.75 pulley on it and need more boost after I installed the intercooler...went from 9 to 5...It has a 6" crank pulley, unchangeable, and I want to put a 3" pulley I have on it. Will I be exceeding the 36k rpm limit? Also, how much shorter should my belt be for .75 inch pulley swap?
