    10psi = 400-420hp.

    just an example as I said, results will vary.
    5 psi gains 100hp to the wheels.??....... You sell this stuff?? or just smoke it

    To the guy that said turbos are cheap power. Please god tell me your joking, Turbo =big black hole in the bank account. Unless you are doing a bad ass DP nitrous set up and nice deticated fuel set up Nitrous will be cheaper. But they are both cool and fun.

    Also my 4.8 made 450/450 on 11-12 Psi with a tiny cam. So yeah I could see that being right.

    Name: Mark,
    God created turbo lag so nitrous trucks could have a chance.

    that's pretty much the industry standard.
    and since it looks like you're having trouble with simple math 350-230=120hp 380-250=130hp
    magnacharger and all other turbo kits claim the same hp gain with 5psi, it's around 120-130hp.

    i know you're just screwing with me, but honestly, tell me where the mistake is in that statement that 5psi makes around 120-130hp?

    no need to blow smoke up the newbie and say 5psi is gonna make more than that.
