    07 rxt need advice on charger

    Hi guys i have a factory rxt and i want to do some mods to it
    i have the following parts brand new at home ready to install

    fizzle xs intercooler
    42 injector (might need to go higher)
    rear rive exhaust
    opas block off
    new wear ring

    i still need to get a super charger and maybe a stage 1 for the grate, wedge and intake and i can tell the seller to change the st1 prop for what ever one i need.

    I was thinking about buying a x charger and i feel that basically what i am doing is making my rxt a rxt-x, i don't want that, i want to be faster so i am thinking about a 2rude or 3rude my question is i don't want to change ecu i want to keep my factory ecu and i want to know if i have to do the valve train upgrade for this chargers, also do u guys recommend this chargers and what speed should i see. Hopefully you guys can estimate my tops speed with this mods.

    If you go to a Rude 2 you will need bigger injectors and a rrfpr, I will put an X charger and then later add a ET137 wheel. A lot less hassle.

    you could go this route ET 68-140 all you would need is 50# and rrfpr and have your prop pitch from speedfreeks and a/f guage. You should be good 78/79 mph, plus this is a hell of a deal on et 140
