  • 125 hp from 5175?

    Is is easy to jet a 5175 for 125 shot or is there more to it? Its only advertised up to 100, but I was toying with the idea of adding another 25. Do I need anything else except the jet?

    Im not asking about supporting mods, just what ever is need for the nitrous kit itself.

    This comes directly from an owners manual!

    Bypass_______N20_______Approx HP.
    42___________36________70
    42___________32________50
    42___________34________60
    42___________45________85(some say 47 for N20)
    42___________63________120(12secondv6 info)

    As you go higher up in the shot, the bypass jet should be reduced in size to compensate for the extra fuel needed.

    Basically,
    At the 63 Nitrous jet lower the bypass jet to around a 34-36 jet for the 120 shot w/ the fuel you need.

        Awesome. Now I am curious about supporting mods. Not about suspension, just motor support.

        I have tr6 plugs, CAI, headers, 3" exhaust. I also have a 255lph Granatelli fuel pump and 36# injectors both are awaiting install and will dyno tune when they are installed.

        Would it be okay with that or am I missing something?

          The hard part would be changing out the bypass jet on the new kits. They aren't made as they used to be, the newer style tee fitting is a single piece with the 42 jet welded in place. I'm not sure how you would change that out.
          Old Car = 12.679 @ 106.5 on 150 dry shot.
          New Car = 2010 3.6l 304hp Camaro

            Easy you just get a new bypass jet tee and swap the whole tee with the new tee.

                At the time for fuel I needed:
                stock pump
                superchips custom tuned computer
                afpr
                stock injectors (19 lb)
                kenne bell boost a pump at 50%

                I you realllllly want to spray a 125 shot....... before you do it make sure your intire exhasut and intake are done. I would like to see a complete 3 inch system.

                Why do you have 36 lb injectors? I still run 19's.

                If you do this.... hit a dyno and wide band tune..... start with a 100 shot and work up from there
