05 RXT Loss of Power
Looking for some ideas...on average I run around 7900rpm at 69mph but recently on my last two outings, my MPH has dropped to 60mph and rpm's were the same as above. My SC washers were done at around 25hrs and I'm at 88hrs now. The water temp has been getting colder and didn't know if that makes any difference with performance. No odd noises are coming from the engine and acceleration seems to be fine.
My wear ring has signs of wear (some scoring) and the impeller has a couple of small dings in it. Do you think I should replace the wear ring now or possibly the SC washers at this point since I'm getting close to 100hrs?

check your supercharger does not spin freely with your fingers

You can check if its totally busted by removing the intake pipe and trying to spin the blades with your fingers
But if its just not slipping right then it might be better to remove it

yes remove the SC intake hose,using finger, try to spin blades

I removed the intake and tried to spin the blades with my fingers and found that it didn't move unless I used a lot of pressure, then it only moved a little bit.

call me crazy as i am def not an expert on these things, however if your RPM is unchanged, but your top speed has dropped, it would stand to reason that the problem is between the connection of the crank and the impeller...so i would replace the wear ring, and see what that does, if that doesnt help then i suspect your impeller is the issue...
like i said take that with a saltshaker of salt as i am not an expert...
