Best venturi size
I know the RXP seems to produce the best top speed with an 81mm venturi. Is this the same for the GPRXP? I have a 2000GPR with an 05 RXP motor. 8650 Riva ECU. I am running the Seadoo pump and 2 large pressure reliefs.

I can't believe no one has any information about this.

I can't believe you are too lazy to use the search engine and find out your own answers.
79-81mm is just fine for the SD pump, and most folks are seeing good results with the 83mm nozzle on the Yami pump.
Some folks are using the Yami nozzle on the SD pump, and are sticking with the 83mm size.
Some are just happy as clams with 85 and 87mm nozzles.
