I am working to transition more to the street so from 10% od 14# I had the pulleys to do this with 55tooth bottom and 67 on top so I have never been this UD on the blower so from boost charts I should get 6# but we will see and if you have done this and have info I would appreciate yours. I have a 8-71 9/1cr 446"
