    How fast should this ski be???

    Im lookin at an 07 with a complete riva stage 3 kit and a rude 3 supercharger. Owner is claiming blower is only makin between 7-8lbs of boost and running 83mph between 8500-8600rpm. This sound about right? Also says it only has 42lb injectors. Is this enough and what would have to be done to run consistant mid to high 80s if i wanted to down the road? Thanks

    A 3RUDE should be about 15-17 psi at 8600. No way you could run a 3RUDE on 42s. I would be every careful about that ski and owner maybe full of it.

    Injectors to small boost to low ask him if he modded the ski or who did because I would bet money he didn't! If he says he did then forget about it because he sure has no clue of what's going on!

    do you still have a 06 rxp?
    a big SC need more fuel so does it have a RRFPR or a AFR gage?
    those numbers just dont add up right
    8600 rpm what does it have for a upgraded ecu

    The stock SC runs just under 10lbs of boost from memory.

    It makes no sense to put a bigger, more expensive SC on and have it running 8lbs.

    If you are keen on it, run a compression test to see how the internals are. I'd dare say if there's no RRFPR then there are probably some burned up piston rings in there.

    +1 to all the previous posts as well, I'd walk away.

    What does an 06 have to do with this thread??hes asking about and 07 he plans on buying....As far as fueling, it doesnt matter if he has a RRFPR or and AFR gauge cause a 3 Rude spinning 8500+ RPM will need more than 42s to fuel it.even with a RRFPR and and AFR gauge....

    the reason I asked about the 06 because he may not know what a stock fuel system looks like
    and I am Assuming not all the parts were listed correctly
    how much boost does it take to get to 83mph? like a mini rude
