    15/20 and x charger rpms?

    Today I went out to test my new mods and VTS in my rxt and was only turning 7400 rpms.

    so far I have
    -x charger
    -42# injectors
    -15/20 skat 3 blade prop
    -4" kanaflex intake
    -R&D grate

    is this the kind of rpms I should be seeing? or am I a little low?

    THat is way to much prop for your setup in my opinion, if its a true 15/20 skat 3 blade.
    I ran one with a rude1 and it could not pull it.

    You need a solas 4 blade 15/20

    crap I knew I should've went 4 blade...
    I don't really care too much for top in so I opted for the 3 blade instead.

    so if I get a 15/20 solas 4 blade I should be turning more rpms than the skat 15/20 3blade?

    Yep, You want to be in or near the 8100 range.

    If you go 4-blade I'd say 14/19, assuming you are using a stock RXT venturi. Call Glen at Skat Trak to get an idea of what pitch to start off with on a 3-blade. Maybe like a 13/17 or so.

    ok thanks for all the help
    I guess I should've done more research.

    You could try to get the 15/20 rebent ( want be easy trying to gain 700 rpm) or it would be better to get a 15/19 skat or less and go from there.
    For your goals definetly go 3 blade.

    I think you should keep the prop - add the Riva ECU, external intercooler and 50lb injectors. Get that thing pumpin!
