SXR Impeller Choice after a few mods

[CD155MX]

I am just finishing adding some stuff to my ski and I am going to be spending a few hours tomorrow trying to fine tune my ski (jetting, pump cone settings, b pipe screw settings, etc.).

I have 2 large hub impellers in my toolbox to choose from and I was wondering which impeller would be a better choice.

1. Skat 9/17
2. Stocker 13/18

My list of mods that would have an effect on my impeller choice are as follows (Bold ones are the newly added ones):

• R&D Timing Advance
• B Pipe
• Jetinetics lightweight Flywheel
• TBM Super Pump Cone
• Flow Control Valve
• Lightweight Waterbox made by Zforce
• Skat Drop Nozzle that I flipped and made into a trim system (the reduction nozzle is 82mm i think)

My gut tells me that the Stocker (13/18) would be the better choice for some freestyle bottom end rip with my above mods, but I'm just not sure. Any help that someone could provide that would give me a stating point for the impeller would be greatly appreciated.

Thanks in advance.

Send the stocker to impros and get Dave to repitch and machine it to a 13/17. You will be very happy with it.

I will be calling Impros and having them do something for me, but right now I wanted to just use the better of the two I already have.

Go with the stocker.
But if you have both, there is nobody here that can tell you which is actually best, throw them both on and try and see.

Will do. Im taking both with me this morning, but I'm going to start with the stocker.
