    X-SC on 07 RXP....

    Installed it middle of last week. Finally got to ride it this weekend. The pull truly is insane compared to the stocker. From any RPM now boost is right there. I have no good OPAS block offs. So im fighting the porpoise big time. 75.3 @ 7990rpm with the trim dam near all the way down. If I bring it up at all it bounces like mad. It was bouncing so bad during my runs I only got a glance at the boost gauge once. Was seeing hits from 9-11psi.

    Oh yea. Its alot louder.

    Ran into an RXP-X and RXT-X yesterday..... Man was that was fun!!

    Nice job bud. I know you're loving that X power. Get those RPM's up, that ski still has alot of speed left.

    The charger, my bad.

    Now something I also did before I installed that charger. I know the SC shaft has the hole in the end of it. But I wanted to share this. I tried to blow a little compressed air into the end if the charger shaft. It would not go. So my assumption is that oil will fill the shaft and that is it.

    I asked the dude if he wanted to count to 3 or if he wanted me to... He said just go. Never caught me. I even let him take the launch. Still caught and passed him at a bit over 45.

    Very cool ... I had no porpoising stock or Stg 1, but once I did the Stg 2 and hit 75 mph, I had lots or porpoising. If you put on RE blockoffs and do some fine tuning with prop and nozzles, you should be in the 77 - 78 range easily I think.
