    The Skat 3 blades are going to act like they have far more pitch than a 4 blade.

    Basically, a Skat 15/22 will probably produce the same RPM's as a 16/25 4 blade.

    This is the impeller i used with my turbo setup on my RXP and it worked great

    Yes, it will work with an 83. You might have to play around with the trailing edge to get your RPM's right where you want them but that Skat impeller is going to act like it has MUCH more pitch than what your running now.

    Grab you a stock x nozzle bro they are 87. Im sure several people will trade you probably as most of us have swapped to stock rxp nozzles.

    Your 15/22 can be worked by Duke in combination to this

    He's looking to reduce his RPM's. The 87mm nozzle will increase his RPM's more.

    I did see that but I saw where he was looking for max holeshot out to 900ft. Figured he would be better with the 87 and just get a re pitch with a 15/20 or 22.

    He's maxed out on that 15/22 having it pitched at a 16/25. Any more pitch added and the blades would be hitting the stator vanes on the pump. He's going to need to go with the 3 blade. Better acceleration with the 3 blade anyway.
