    Stage 2 question on RPMs

    Ok heres the ski, 07 RXP, green wheel, Riva rear exhaust, 42# injectors, catch can, Riva 3" intake, Riva grate and a Solas 15/20 impeller. My max RPMs are 8000-8020. I just got my 4inck Kanaflex should I try that to get more RPMs first than move to the prop or just plan on doing the prop now also?

    Wait till you install your 4 inch intake..Your RPMs will go up once you install it..Then adjust your prop accordingly.

    I would change out the air intake and check rpm then pitch prop to needs.

    A little off subject but are you running an intercooler? I saw it says stage 2 but I dont see a intercooler listed in your mods. I have a similar setup and I was told that I probably couldn't turn a 15/20 but I added 2mm to my 14/19 and still running 8120-8140 in the heat. What mph are you running?
