    what impeller for stock 03gtx?

    looking to mod my 03 gtx for jumping waves.
    so what kind of impeller should i get for good hole shot?
    i also have a 04 rxp pump housing, got rid of the plastic crap.

    For low end grunt, the Skat 16/21 works great and also works up higher as well

    I'm using a Solas 12/20 on my stock 03 GTXsc and really happy with it. Not a lot faster, but acceleration was improved.

    Only picked up a couple of mph, but I never tested it without the Riva intake grate and pump wedge to see if that's killing off the top end. Besides, I prefer accelleration over top end. Makes my arms longer don't cha know.

    To retain ideal engine rpm and gain bottom, we alter both options to maximize performance. The 16/21 Skat that we change makes a nice increase on bottom end, as does the 12/20 Solas that we change. The Solas also picks up speed. Either one can be improved on compared to out of the box gains. The outcome pitch is kept to ourselves, but worth the few extra bucks.

    so how much are we talking for a 12/20 thats tweeked?
    the only mods are riva intake grate & 04 pump.

    It's only a few bucks over the price of the impeller. PM me if you'd like.
