?s on x-charger on a rxp
so i have been reading this forum and i cant figure this out i want to put a x-charger on my rxp with 42#injectors, but this is where im confused some are saying to use a rrfpr and some dont. so do you have to use a rrfpr.

If you are gonna have everything else stock on your 215RXP then the 42's will do just fine.
The problem is when you go 4inch intake and a External IC. Then you will need to raise your fueling just a bit with the RRFPR.

I don't have any free mods(reverse bucket mod,ride plate holes filled and so forth). I also have off power steering still as well. And I'm in south Florida hot weather. and over weight hahaha
good luck you will love the new acceleration!

You absolutely need the intercooler. You will break 75 with the intercooler.
We have that very setup on my significant other's ski (rXptina) and she runs a solid 76.
Check out her sig.
You said you want 75+
If you want to consistently run 77 or so, go Rude1. The X charger will get you a mix of speeds in the 74-76 range. The Rude1 will get you a solid 2mph beyond that and better acceleration.
Just my .02 but the intercooler is a must no matter what and then you need an rrfpr.

ran the X charger, 42's and 4" kanaflex intake most of the summer with riva exhaust and GH waterbox, free mods, and 15/20 prop on my RXT and ran 74mph.

what about an x model fuel pump instead of the rrfpr? and of course the 42's. basically makes in an x in an rxp correct?
