    Adding some things.....

    Adding a few things to my new ski.

    X-charger and Fizzle IC, Rear exhaust, Prop, RE BO's. I want to forgo doing the regulator and 42's and go with the 50's. Is that a wise move or am I asking for trouble. I went with the 'traditional' setup on the other ski. 42's RRPFR @ 63 psi, Fizzle, X-Charger, etc.... 11.8:1 at WOT... 12.2 idle.

    I just want to have less in the hull. Could I get away without running the RRPFR and 42's and go straight to the 50's with no RRPFR..... Maybe a Rude controller or something.....
    I also have an LC-1 in each ski......

    For the extra $35 (DIY method) I would go with the RRPFR.

    You could run the 48s with a controller, be a nice setup, better then messing with RRFPRs IMO

    50s would be too much I think for a X charger.

    I run a x charger on 50s with the rude controller. I also have a rrfpr but only use it to adjust my base pressure. Its not setup for rising rate.

    The ski would never want to idle with 50s. They struggle with 42s with stock fuel setup. Way to rich.

    The rude controller is very nice.

    Make sure to use the viton seal in that charger. Pretty sure you bought some from me awhile ago. If not Jerry now sells them.

    Thats a darn rich idle afr on your other setup. Must have a rough idle.

    Can you tell me about this DIY RRFPR?

    I have the same setup on my 06 RXP. X-Charger,42lb injectors,Fizzle IC,RRFPR and see 12.1 at idle as well. What is the best way to lean out the idle more?
