x charger and 8500 boost #
i know water for fire saw 13.5 psi out of his x charger at 8500
just wondering if that is normal or does he have a freak charger..guage variat???
i know there are a few people running x chargers w riva ecu what # are you seeing...
mine is a little low comparatively ...as well as my rpm ...working it out ..
just want a broader survey of what i should be looking for....as far as # go if every one else is seeing 12 12.5 ..i am on track if everyone else is seeing the 13 i need to look harder...

I saw between 12 and 13 at 8600 in 85degree weather. Bone stock 09 X charger. Stock slip was around 12 pounds so its possible if it were tightened a bit there might be a gain.

I adjusted my slip to 165in.lbs before i ever put it in my wifes boat.
It is a 09 X SCer.
I saw 13.6 at 65 degree's and 8600rpm's..
I bet in the summer it settles around 12.5's.

With flat water, mess with the trailing edge or nozzle rings to get rpms to 8550 and you should easily hit 80.xx to 81.xx mph. I ran a full summer with the Riva ECU, 50s and stock X charger, hit 81+ mph at 8500 rpms, great setup.

bov was leaking ..tightened it down to hold he extra boost and saw the 13 psi at 8600 so found the boost no i need to get it off the limiter
still wondering what kind of boost # a mini rude puts out at 8550
