    LS6 vs. FAST Intake

    I am going to be getting some patriot stage II ls6 heads and need an opinion. I currently have a ls6 intake,80mm TB, and a TR224 cam. Should I get a fast intake as well for my combination or is the ls6 going to be enough. Would I see a huge gain between them.

    Ls6 intake is definitely better than an LS1 intake but if you talking about the FAST 90mm intake it will definitely show better gains than an LS6 intake. I would think that even the FAST 78mm intake would show better gains but if your gonna spend all that money I would personally get the 90mm one.

    You will see no gains from the FAST 78, but the 90/90 combo will show a good 10-20 rwhp. I would get a Mamo ported 90.

    I'd use the LS6. I have 90/90 but don't really think it's worth the money unless you really, really want it.
