85 & 87mm nozzle
What nozzle is everyone running on their Stage II 12R and 13R GPR's
Please state Pros / Cons of holeshot, top end, 1200 & 1300.

many people will tell you one is better than the other, but I ran them BACK TO BACK and saw no differences between the 2

I have NOT tested them back to back. But every pump setup is different, and 2mm (very small size difference) is HUGE on the gpr pump packages. Throw in variables such as small hub and large hub, setback, non-setback, tolerance stackups and all that other jazz, and I'm sure you can find a difference between the two.

I got several emails with good tips and replies on this.

Has anyone experienced:
> any new results from any reduction nozzle testing confirmed ?
> any changes in performance due to different prop/motor cc/reduction nozzle configuration ?
