04 RXP Supercharger to X Charger
I currently have a stage 1 04 Rxp with about 185 hours on it. I am still running the original supercharger and put in a 14/19 solas. The ski runs mint and I ride it hard all the time here on Long Island. I am currently running about 8050 rpm and seeing about 70. I rode the new X and was'nt really that impressed with it. I mean to trade my ski in with those hours and put up like 8 grand or more is not worth it to me. I also tried a 15/20 solas and it put my rpm's down to 7700 and kept the same top speed.
I read a few things about the new X supercharger and was wondering if I can try replacing my charger with the X one and throwing that 15/20 back in. I think that the extra boost will spin that 15/20 to about 8000 rpm's and here comes some more speed!!
Will it work or do I have to do something else??

Ever thought about fuel lean conditions...?
I don't think the stock injectors would be enough to provide sufficient fuel needed with that amount of boost.

If you are going to replace the stock s/c with the "X" s/c, you will need at least 42s, but you'd be better off with a RRFPR. I don't know if you're going to put an external intercooler on, but I went from Stage 1 to the mods I have now. When I first took my RXT out with the 15/20 I was on the limiter, it's perfect with a 81mm nozzle ring though.

I too am looking to add the X charger on my RXT along with the Pirahna or maybe XS intercooler and RRFPR to crest the 70MPH mark.
I know there are threads about the X charger because someone told me about them, but I havent been able to find them. Anyone have a couple useful links handy?Last edited by Gus13letter; 06-02-2008 at 09:11 PM.
