ET on a RXP X260
Looking to move my ET 70/145 on the RXP x260....has anyone done it?
if so what all did you change (fuel pump, injectors size, impeller size, vtec map...)?

I did it. But when I did I went to motec. On the stock ecu you obviously will need some kind of tune. Or a stand alone ecu. Rising rate regulator. A walbro fuel pump is cheap insurance. I would say run those vtech 1100cc injectors with there logger to get it dialed in right. If you have the money to spend then without question go with the motec m130 and injector dynamics 100# injectors. You will need a 15/22 prop as well. If you haven't done so already you will need a larger better IC. I like the riva gen 3. Again its all a matter of how much you are willing to spend. Motec is the shit hands down! But it's expensive

Also this may have been a bad intake but I did split a stock intake in half with this charger also. If you decide to go vtech just be prepared so slow support and response times. Search the forum you will see

Gut your water box or get the riva one otherwise you will keep popping the water box off the midpipe with this charger

Vtec has been spot on for me...I get super quick response from Jonathan....and I'm really happy with there maps
I have a 15/22 sitting on the shelf....did the IC upgrade to the older IC with the riva pipes....also the riva through hull exhaust
How did you all gut the new water box? Anyone using the Rotex hydraulic kit?
I also have some 60# injectors sitting around....not sure if I should just run with them...fuel pump is a must.

Stock injectors aren't going to be able to fuel this charger . The amount of boost it will run can kill your motor in a hurry if it's not tuned right. So if you are running vtech I assume you are logging afr with there logger?

We have many skis with rude 3 and similar sc.
They all run setup similar to this:
Stock fuel pump and regulator.
4" air intake.
Upgraded waterbox and intercooler.
Thru hull exhaust.
R n d intake grate
15/21 or 22 impeller.
Or speed freaks 13.5/21.5 w setback mod.
And of course the Vtech programs.
They work very well with this setup and have won several races already.
This setup is for Bosch based skis only!
