Follow up: Got back on the water today, prop is ok now and it ran ok. Half way through the ride I closed the middle screw leaving only the top screw at 4 turn, it woke it right up! It felt like it was pushing a bit too much water and would clean out after a few blips of the throttle, by reducing that the revs are much better and almost instant even after a short bit of cruzing. It runs as hard or harder than the SJ limited chamber, and I'm running a long cone now where I had the short cone on the SJ setup. Basically its darn near what a drypipe would be doing, exept there is some steam created from the water thats injected. I'll try to throw a tach on there next time out to verify my rpm. My evaluation would conclude that the SJ chamber needs more water to get bottom end, and the Blaster chamber needs less water to get into the mid/upper rpm
