Re: crankcase evac
buddy of mine just put two on his with a guage and some kind of regulator, but he says on his guage that each pump is making 5" of vacuum. He's taking his car to dyno and to the track sometime this month to see what kind of numbers his car will make with and with out the pumps. He's a mustang nut and i guess the mustang guys are doing this. His car ran in the low 9's before he built this new motor. I'll post some numbers as soon as i get them from him.
