    supercharger question - Xcharger

    still learing bout this supercharger stuff.. so got a question..

    if increasing revs from 8100 to 8600 (ecu remap) + valve train upgrade + injector upgrade, will the standard xcharger produce more boost considering more rpm ??

    if so what sort of boost would the extra rev generate??

    Yes you will see more boost at 8600rpm. At 8100 you should see around 9.7 and at 8500 you will be looking at around 11.1

    I think some where on the forum there is a thread on x charger boost and others chargers. To answer your question. More boost is better. If you are upgrading from a standard SC then the X will be great.

    Upgrade that X-Charger with an ET 137 Drop In wheel. With a reflash, it will really wake it up....

    What ski do you have now?

    NO, You need an RRFPR and would also help to have an external IC such as a Fizzle. A set of 42's and you will be golden. Stay with a stock nozzle if you want acceleration. You could go with the 81 for top end and overall speed.....

    I think your numbers may be a little low oz. At 8100 rpm I see 11lbs and at 8600 I'm seeing 13.

    My X-Charger saw 10.5 at 8100. 11.0 at 8160.

    The ET 137 shows 13.5 at 8160
