    Welcome to the GH!
    with a cmd and a rrfpr you might be able to get enough fuel....well when its hot anyway at 8100
    you will need a big prop.... 15/22 will not be big enough
    my gtx with the 140 can spin a 15/22 to 8700

    Chris is right about having to get a RRFPR and a CMD or some kind of fuel controller...you will need more fuel on top and less on the bottom...As far as props...I ran a 15/22 on my 06 RXP with a 2 rude(which is also a 140mm wheel) and stock ECU and am only seeing 8120..even when i ran a Riva ECU i could only spin that prop to 8200...I dont think the prop will be an issue,especially on and RXT....

    Why do you want to put it in the RXT? Just because its lying around?

    Thats a big charger to take a gamble on...you'd have 2 down skis if you can't watch the AFR's...

    Correct.....If you have no way of monitering your AFRs, you could wash out the cylinders on the low end,and lean them out on top which will then make your motor go boom...You WILL need a way to moniter your AFRs and a way to adjust your fuel by way of some sort of fuel controller and regulator

    that's just not a charger....that's a big charger
    with out a cmd it will be pig fat until 6-7000 and then it will be lean
    and it could get very lean near 8000 = boom....broken piston or blown head gasket
    do your self a favor and not run that combo with out a afr gage
