    Super charger and injector questions

    hey guys,I have an 06 rxp that is currently stage one...I keep flip flopping on the extent of the mods that I want to do....my question is what are the largest injectors that can be run on a stock ecu without having to install a rrfpr and what supercharger wheel is needed....just wondering...trying to build a decently quick machine without to many headaches....thanks..


    p.s. Mods that will be added to machine over winter are riva waterbox,thru hull,riva intercooler,greddy bov,pump ext,riva rideplate,heat ex set up,RE blockoffs,catch can,groco strainer...

    I would suggest an X-Charger and 42's, but you stated that you don't want to run an RRFPR.By adding the intercooler you will def. need an RRFPR and for tuning an AFR meter.If you forgo the intercooler then you can go with X-charger and 42's and be done but I wouldn't ride in the winter or below 55 degrees........Read my sig as you can see plenty of performance for what little I've done so far.Hope this helps.

    thanks for the info...I was torn between something a little more tame or the 3rude and 50's which i knew would require the rrfpr or probably the begi setup..the afr gauge, boost gauge and all the other bells and whistles ...oh well....its just money...ouch!

    I would go with what you were going to add, then put in 42 lb injectors and a drop in wheel like the Riva Gen2 wheel. Great setup, cheap, well-proven by many people.

    With all the mods you gonna do this winter,do an extra mod,weld in a bung in your j-pipe so you can measure your afr.
    You can't put just anything on and recon you'r good to go.
    You really must know your afr ratio.
    I know this seems a bit complicated ,but believe me it saves your engine!

    highly recomend a rivs s3 housing and wheel and 42 s .....way more volume and acceleration over just a wheel...that equates to way more acceleration...did both...s3 charger has so far been the best bang for buck i ever did....

    a x charger w 42 is fine as well ..as long as you dont add an intercooler
