04 RXP-215 vs 14 RXP-X
I ran into a 215 owner on the lake this wknd.
He wanted to run me just to see what his would do.
He was sure I would beat him but wanted to see how bad or so he said.
After we a few runs he admitted he had this list
42's for Injectors
4 inch intake
Ride plate holes filled
Diff prop, didn't tell me pitch
Stainless steel wear ring
Intake grate- didn't give specifics
My ski consistently GPS at 68.
I let him use my phone today and he pulled 70
on the GPS.
Overall it was a fun run , but it's about time I start modding I suppose.

I posted something similar last year. I ran my buddies 2013 px with my 04 rxp. Only thing my rxp had was a solas impeller and I pulled the intake hose off my supercharger. race was dead even out of the hole and the first 100 then I started pulling away at a few mph. 70 seems slow for those mods he has. I would say I was probably doing 69 or 70 practically stock

70 seemed slow to me as well. It was Hot ,and humid when we ran. It didn't do either of us any good , but I ran mine very hard before he asked me to run ,and his was parked for a couple of hours prior to running so I'm sure I had some heat soak.
He told me he was still on the factory I/C so that's definitely not helping him.
I have 2 other friends with Stock RXP-215's. One 05 ,and one 07. I had no trouble pulling away from them out of the hole ,and maintaining a decent lead.

The different intake grate could have slowed him down..stock intake is the fastest when it comes to calm waters. My opinion is that you need an after market grate when you have serious mods so as to keep your ski hooked.

well since then I put an x charger, ic and pump impeller, 4in intake, gutted 08 waterbox, and 42lb injectors and the ski runs a lot slower. obviously something wrong with the setup but I haven't had time to look at it. Either the 42s are way rich with the stock computer or my intercooler is leaking

Would reliability be compromised by running a 8350 Vtech Tune on an other wise
stock engine? Can the stock valve train handle occasional extended WOT use with that tune?

can doo does erase the max rpm record
but that is a red flag that the ecu was tampered with
