I don't have the ss and still haven't run mine top end, so can't help much. But, I don't think the 26 trophy is the most popular prop on our setup. I have a 27 trophy but plan to try the hydromotive 28 soon as I learn to drive it.
I have run mine 79 gps at about 6k rpms.
Still learning to drive on top end.
Chopper has allison cut from performance in soddy-daisy. But top-end virtually same as trophy and hitting rev-limiter. Billy has added cup but not there yet. He says I should see 88+ with this prop and I agree! These little 200xs are awsome! B&WB mag estimates hp at more like 230 and I sure wouldn't dispute that.
