    Budget RXP kicks butt!

    I built a Budget RXP to run hard and have fun.

    Home made rear 4inch. $40
    XS IC $200
    STG III SCer $850
    15-19R $235
    Skat 82mm ring $75
    42lb injecters $250 Rotax racing ones.

    I ran 8100-8150 this weekend and it was just a blast to ride.
    I mean for the money this thing can't be beat.
    I was running off all the big boys on the water.
    All I can say is if you have a full stage III how can you NOT get 80 out of your boat? I saw all day High 76's with low 77's with less than a 1/2 tank of fuel. The 15-19R was perfect with a 82mm Ring. It sarted at 8100 with flashes of 8150.

    One bad thing happened again. I poped a IC tube again. This stg III moves some air. Gonna get smaller T-bolt clamps.

    i have a stage 3 boat and can not get past 79, lol. I think my intercooler is too restrictive, i have only seen 10.5 psi max and this weekend i ran 9.5 psi 8450 rpm 81mm ring and only got 78.2, there was a terible current and crosswind, maybe that was my issue.

    anyone care to lend an XS for me to test, , seriously though....

    Ray I was up your way about 2 weeks ago. I left you a note on your front door. I was at the lake house (Travis) and had a great time. I want to come see you on Friday or Saturday.

    My STG III SCer ran 11 lbs on my gauge, but it has been rebalanced and cleaned up to NEW from Two2's ski.
    If you want I will send you my XS system to try your Riva. PM me. If you want.

    Very nice. I had similar results with my Rxp. I had a 15/20R, but all of the rest was the same.
