Seems like im stepping on some toes in here. I dont care whether i make 5 psi or 50, i just wanted to know what is normal for these cars. 5 psi seems like a pretty low number to me. Most supercharged cars tend to have around 8 psi. Sure less boost=better flow but if your boost is supposed to be a certain amount and is not reaching that amount, does that mean your engine magically became more efficient?
