    Stock X Charger vs. X Charger w/ Riva Pro series Wheel & Viton Seal

    There are a few guys on the forum selling their SCs, and in my n00bness I'm trying to make sure I understand what I'm looking at before I decide which way to go.

    If I buy a stock X charger, I understand that the only other thing I'll need to do is put in 42lb injectors and call it good.

    If I go for an x charger that has the Riva Pro Series wheel in it, my understanding is that it will need the 50lb injectors, but will I need to do any ECU or other fuel system mods?

    Thx!

    Most likely the stock ecu will be ok. just need the right injectors and maybe a rising rate fuel pressure regulator. (rrfpr)

    I'm not familiar with that wheel. how many psi dose it put out?

    Also even though you can use a stock ecu these engine really make some power at higher rpms. (ecu, springs, prop pitch ect.. to run higher rpms )

    any other ecu you will be raising the rev limit and you will need a valve train upgrade.... keep things simple and gas and go the ski ..... until you get hungry again... if you bolt on too many things at once and run into issues.. you wont know where to start to look to problem solve and fix...

    I still think x charger is the way to go. I read great things about the ET127 wheel, but the x charger will give me even more potential in the future.

    just go the 127 ET.... u will love it. Best bang for buck on a rxp. Then if u wanna go further in future, buy a bigger SC (ET, Rude, XXX) and pass the lil ET on down to the kiddies. But that 127 drop on is really light and pumps out the boost. best set up for least amount of SC drama/maintenance

    The bigger the boost number your running the more you need to check your slip.
    Higher boost will eat washer faster.
    Also the higher the rpms your running the more you need to keep tabs on it.

    Thats why several are going turbo. No slip adjustments and higher boost.

    I thought it was for better fuel mileage--you know, to "Go Green"?
