Rxp w/ X charger & stock Ic...stock inj? impeller opinions?
Getting ready to go back to "stock" with my Rxp. One problem---I've got an s/c from the Rxp-x.
I ran my RR wheel with stock injectors, stock ic/4" rear intake/14/19R and loved it. It had a ton of mid-range and was a blast to ride.
This time I'll have the X-charger and a 4" front intake with the stock ic. Looking for opinions on the injectors and impeller. I have 42's I can throw in it, but I'd like to run the stockers if possible.
I was going to run a 14/19 3-blade. I loved my 14/19r, and if the 3 blade has any more holeshot/midrange I'd be .

Can be wrong but i think:
4 blades = better for holeshots & acceleration
3 blades = better for top speed runs
As far as running the stock injectors with the X S/C...i think you should at least put the 42's in...but again....can be wrong.

i think 42's are stock on a 2008 X model so i would add 42's especially with 4" rear intake!

I do agree. The X SC is roughly = to the Riva S3 SC performance wise, so I would advise the 42# injectors to be safe. However, now with the Rude rising rate fuel regulator you can stick with stock 38# injectors and not worry about running rich with the 42# injectors on bottom end and midrange.

What do you think about the impeller? I really liked my 14/19R, the 15/20R is great on the top-end but is lazy down low. I'd go with a 15/19R 3 blade--but I don't think this setup will have the guts to turn something that big. That's why I was thinking the 14/19 3 blade--maybe with a slight re-pitch.
It will be a 4" front intake--not the rear. I had the rear and like the sound/performance, but didn't like sucking up water everytime I went a little crazy.

I couldn't believe how much acceleration/pull I lost when I switched to the 15/20R---not worth the extra mph IMO.
I may have to try the 3-blade 14/19.
