i wouldn't waste your money.... if your prop is tuned right you shouldn't need an anti-cavitation cone

You don’t need a longer cone to fill the space between nuzzle and the pump if you still using the wedge ?

Should be both. There is no difference in the pump. Except the fins on the RXT I believe.

It definately loads the pump up. It drops you about 50 rpm and you gain about a half a mph. I think it's a good gauge to see if you need a repitch. If you put it on and you drop to 8050-8100 you know you are right ont he money with your pitch. If you are still banging the rev limiter with it on you probably need to pull a mm out of your blades.
With a wedge on, you have offset your pump it makes since to get the space back with a cone spacer. Makes even more since for it to be angled along with the wedge for water flow. I bet that's what the new cone does.

Still dialing it in. I am running about 68 but having issues. I think I lost some rpms from overfilled oil and I have my 2.5 polished chrome tube in for my SC to IC. I think my 3 inch is pulling away too much boost. I don't have a SC wheel so my stock one is probably struggling to get air in it.
I'll know more this weekend hopefully. I ran 68 with my wife on it and a completly full tank. I went to do solo testing and I was having oil issues and only running like 67 and my rpms were going down to 7900. Might have been the cone spacer too dropping me 50-100 under the performance threshold. air/water temps were same too 80 air 70ish water.
