    How to Mod properly (Supercharger, Exhaust, etc..)

    Alright guys I'm at a cross roads with my '04 RXP. Supercharger needs to get rebuilt and I'm thinking about just getting a bigger S/C instead. Want some more power/boost. Whats the best route to take as for as parts and mods(S/C, Intake, Injectors, ECU Tune?). What will I need for me to drop in a larger S/C? My ski is completely stock, just has a RIVA intake grate.
    I want to stay around $2,000 +/-

    Here's my advice. Go with the X model supercharger and injector kit found here in the store
    http://www.4-tecperformance.com/inde...oducts_id=2435

    add this air intake

    This pump impeller
    http://www.4-tecperformance.com/inde...products_id=12

    always install a new wear ring with a new impeller. This is the factory replacement
    http://www.4-tecperformance.com/inde...roducts_id=518

    This is the best replacement wear ring
    http://www.4-tecperformance.com/inde...roducts_id=401

    You already have an intake grate. Finish off the package with a pump wedge and OPAS blockoffs.

    OPAS kit here

    Or you can rebuild your charger and do the et 127 +3 wheel that jerry offers. Plus the prop and everything else he recommend

    Will I need to get a new tune/ECu Flash for the added mods?

    Can the stock exhaust still be used with the mods?

    And the other BIG question...Will this get me to 80mph?

    no, x charger with stock rpm on stock tune is about 73
    80mph you will need at least et137 and a more rpm tune
