Thread: Upgrade supercharger?
11-09-2014, 04:26 AM #1
Hi, I'm a bit of a noob when it comes to jet skis, I have just purchased an 2007 seadoo Rxp 215, and it is due for its 100hr service, which means I need to get the supercharger done. It has been brought to my attention that it may be a viable option to switch out to an xcharger and 42lb injectors. My Rxp is completely stock except an after market intake grate.
Would this be a viable option, and where would be my best place to source these items at a reasonable price that would post to australia?
any help from those in the know would be greatly appreciated.

Rebuild the stock charger and install an ET 127 wheel, 42lb injectors and a prop repitch and you will be impressed. I did this to a previous RXP, put about 60 hours on it afterward with no problems at all.

Ok thanks for that info, so does changing to an xcharger and 42lb injectors not just make it the same as the 255 model?

To make it same as 255 requires an external intercooler and 255 ECU (engine control unit). You can run an x charger w/o the 42's as long as you keep the stock air Intake....once you modify the intake you start running too lean and need to run 42's...it will be rich on fuel at low rpm's due to the emm thinking it has 38# injectors until the added boost (air) comes on

As you have stated, it sounds like it would work, just not completely safe if the engine starts to lean out.

I had it and was very happy with it. No issues at all. The X charger gives you more options down the track eg bigger boost wheels when you want more speed. Its a cheap option.
The engine will not run lean with 42's.

Ok, so I could:
1) run an xcharger with stock injectors and stock intake and it will be fine.
2) run an xcharger with 42 injectors and a moded air intake and it will be fine
3) run the rebuilt stock charger with a et127 wheel and 42 injectors, but would need to change the front and rear housings anyway?
Unsure of the difference between an xcharger and running a et127 wheel.
I am interested why the ski would be put on death row by doing the upgrade, as I don't think running rich on low rpm should cause it to let go? As opposed to running lean.
Can the stock ecu in my Rxp be modified or retuned to compensate for any modifications like this, or could you get a ecu from a 255 setup and do a straight swap?
