    That seems like a lot of mods to only run 72. I'm wondering if I should buy an X when my 04 runs 72.6 with just a few minor mods. Seems like the X should be faster. Do I gain much going to the X?

    My RXT-X has run a best of 72.6 and I think it will go faster with prop tuning. All I have is an R&D grate basically. He should be going faster then that and he should be turning better rpm's. Wonder what air temp he is running in Abu Dhabi. By the way, the "X" ski's have way better holeshot and acceleration than the rxp's and rxt's. I've totally spanked a stage 1 rxp with my holeshot.

    You need to figure out why your RPM's are so low before you do anything else. You're missing close to 300 RPM.

    You're kidding me right? Do you not think their weather conditions are going to affect RPM?

    My point is that his speed is good for those RPM. Bring that ski here to the states and I bet he picks up that 200-300 RPM and 2-3mph. He just needs a prop tweek.

    You need to reduce nozzle diameter, either get the riva set up or get a stock rxp nozzle, i personally gained over 2mph by going from the stock X nozzle to the stock rxp nozzle. If you really want to, go with an 82mm ring with riva's kit and gain even more speed, but it will cost you noticeable acceleration compared to the stock rxp nozzle (83mm ring)
