RXP-X mph results w/ video (gps)
I decided to take the ski out and see how much better it ran with temps in the upper 70's to mid 80's. I didn't quite get the early start this morning as I wanted to, so I missed the nice cool air. Last time I rode, temps were in the 90's and the best it went was 77.0mph @ around 8080-8100 rpms. This time, it went 78.0 @ 8180 and clipped 8200 every one in a while. It was on the low fuel buzzer. I had someone inquiring about current, so after the 78.0mph run, I picked up, added some fuel and went where I knew they generally have current. Today it wasn't as much as normal .4-.5mph. As figured, it did yield a higher mph. With the current it went 78.6mph. Mods again are listed;
4" front intake w/ no filter
R&D intake grate
reverse bucket mod
ride plate holes filled
2 degree Riva wedge w/ vts rod extension
My ski still has a bone stock prop that has never been off the ski or pitched. I want to mod more but am leary considering how well it runs for how little is done to it. As I mentioned in a few other posts, guys like jp1300r, troyheb, Josh (BAYOURXP) have been a big help in steering me which direction to head and what to buy and what not to waste money on. I would never imagined something w/ so little could run as well as these skis do.
Here are a couple of videos. Excuse the poor quality being they are from my phone. A buddy of mine is in the first video (jeans and all) lol. He outweighs me by about 30lbs and the ski really doesn't seem to mind it.

I still have a good ways to go for that. lol I think I got just about all I can expect out of it with whats done. As others mentioned, going any faster would probably take a good bit more work and $. I'm just enjoying it at this point with the little $ spent on it. Plus its pretty cool to go that fast with a stock exhaust and surprise people when it runs like it does. I have to give all the credit to this board...the members kick a$$ when it comes giving suggestions etc.

That is unusally fast considering your mod level. You must have a very fast hull.

Great speeds. Sometimes everything comes together just right and for Keith it looks like it has.

That is really fast for those few mods. I would expect 74 mph, especially with a stock prop. You are lucky. Might not want to mess with it too much.
