    WOW Theses X Chargers a great! Results!

    Guys I have been working on a RXP built for my Wife (See avatar) for this comming year. THe goal was to have a FAST and very reliable boat That i don't have to wrench on. Well I think I am close.

    This is with a STOCK untouched X SCer.
    Basically a X boat in a RXP with Riva ECU.

    Heres the kicker. I saw 13.6 lbs of boost with a stock X SCer at 8600rpm's. This is amazing.

    Cracked off a 82.6 and all over the rev. Limiter.

    This is something ive wondered myself. Is 8600 rpm going to be reliable in the long run? You obviously think so.

    I have a Riva ecu here. Im thinking about putting it in my significant others ski. Shes running 76 now with a stock ecu..

    Bro I sold my yellow RXP and it had 140 hours of 8550 all the time! I beat the crap out of it and it ran great.

    Yes, I don't mind the 8600 at all!

    Its not just plug and play but I think at 13.5 lbs of boost it could be reliable at 8,500 rpm if is setup (afr ect) and monitored with outside changes.

    Once you turn 8,600 rpm your internels need to be spot on for life.
    So is hard to say were the reliabilty changes in the boost catagory at high rpms.


    Austin, that is very impresive. Is that with XS intercooler????

    Guess all you want, I had to look at my Dynotune gauge a few times to believe it, but the 82+ MPH runs prove it. The kick ass (XSCers)!

    Yes, with a XS IC.

    I was also on your old T-X today. Ray (Sundance) and Chin (enforecer) were there and we were laughing are asses off. I was on the limiter also.
    Gonna change to a 15-22 prop and go back tomorrow.

    Each and everytime I hit the throttle I saw 13.6 on the gauge. It would see 13.5 sometimes, but mostly 13.6
