I was looking at the other thread about the guy wanting to pnp his own head . My question is I wanna go s/c . If I get a fr head and put on a supercharger it will lower my boost . I thought getting a pnp head wouldnt do anything to the boost . I thought pnp would increase the flow of air and gas and exhaust . So I thought after you got one of those heads and put forced induction on it would give more power than before. Please explain it to me because I dont want to spend an money on something I dont need.
