    Prop repitch on an rxpx ?

    Hey all,
    I just had a 15/20 and a new f 1000 ic put on. Prior to those parts I was spinning 8350-8400 and seeing 76 dash. Now I see 7950-8000 with dash speeds of 73. Is it just needing a simple repitch, or should I look elsewhere too? I noticed the new intercooler does not shoot water out like the stock unit, but it appears to be plumbed properly.
    Thanks in advance.

    I would pull the prop and have it trued up to a 15/19.

    So the question is, are there any real gains to be had by going to a 15/20 with only average supporting mods? I'm @750 msl and see 100° often in the summer. Should I have just had the stocker repitched a bit? Either way, I'm taking off the 15/20 and doing a repitch to a 19 and will post back. The prop really seemed to bog down all areas.

    I had a 14/19 which rode my limiter at 8400 so I went with the 15/20 and now I am down to 8200-8300 with 77 on the dash, I am thinking I need to raise my limiter and put in the 14/19

    What is your Target RPM? Do you have a valvetrain upgrade? I'd back it down even further... go 14/18 if your springs and retainers can support it.

    I'd like 8200/8300. That seems to be the sweet spot with stock valve train.

    Bend the stock prop to your needs. I took my stock prop (repitched a lot) all the way to 82.2 gps mph


    Turbo and 15psi 9000 rpm
