So I have a TSP 228R 112LSA cam installed in my stock short block LS1 w/ 799 heads. I am currently installing a 7868 turbo and although I know the cam is not ideal for the boost, its going to have to work. (Car weighs 2700lbs). I am currently deciding which Tial Blow off valve I need (based on amount of vacuum the engine pulls) but unfortunately I did not check my vacuum prior to starting my turbo build. From what I have heard the 228R cam is somewhat mild so I am thinking my vacuum has not dropped much. Anyone know or care to guesstimate how much vacuum my setup would pull? Any help would be appreciated.
