    Cool which impeler for what ?

    hey guys I have started modding my rxp and really enjoying tinkering with it .
    I have a piranah power kit (ic,thru hull ex,10 psi sc impeller )
    worx maxiloader intake grate , rideplate holes filled ,piranah power air filter.
    future mods will include rr pro ecu with #50 injectors
    I have been told many different things about which impeeler will work best .
    I have a solas 13/18 srx swirl impeller , which I hope will give good hole shot without losing top end . I also thought of getting a 15/20 solas as with the mods it should not be too tall .
    thoughts and opinions as well as past experience is desperateley required .
    p.s will post some picks when I have my boat back together .

    Go with a 15/20 or 15/20R for now. Its not to tall for your mods. You should at least run some 42lb injectors with SC wheel and IC. Pitch the 15/20 and you should see speeds of around 76+. I have!
