a buddy of mine has a bone stock 07 rxp with metal washers added, he is nearing 100 hrs and is contemplating supercharger upgrade to x charger rather than rebuild his with the oem rebuild kit, if he does upgrade charger is stock injectors ok and will stock prop be ok,

He will need 42lb injectors and prob have to tweak his prop.

Yes the stock injectors are fine but he will have to add some pitch to the prop.

x-charger on a 215 motor with stock 38lb injectors will run lean.
He doesn't have to re-pitch the prop... he'll be on the rev limiter some and will just be leaving some speed on the table. Yes its ideal to tweak the prop to get the most speed out of it... but the ski will still be rideable

I did this same exact thing not to long ago and rode all day Saturday last weekend with no problems. I know it was probably not running as fast as it could with the stock injectors but it still ran pretty fast. I change out my SC with a new X-cahrger also. I am going be putting on a XS intercooler, Riva intake grate, 42 injectors, rear air intake, 15/22 prop (tweaked to get good RPM) and a RRFPR. I have been told that this is a good setup and it is the direction that I am going in to modding my RXP.

I have personally never ran this set up...
But according to jerry you can run a x charger with 38s as long as evrything else is 100% stock...meaning stock air box and all...
I would also like to say I would never chance it though...

at least purchase a Rrfpr but if you do that might as well get 42's cheaper. I do know that if you do go x charger and 42's and 4 inch intake.. it will start to lean out too much.. at least thats what I am witnessing. Play it safe brother.
