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.

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.

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
