    75.3!! Wow that is very impressive. If you fill your rideplate holes, you might pick up another mph to hit 76!

    Interesting choice for the prop. Isn't stock 14/25 and Riva S1 15/22? I know I tried a 17.5/21 on my turbo ski and it was a bust. My 15/21 worked better, so now I'm going to 15/24.

    Did you re-pitch the stocker or buy a new prop? If you bought a new one, I'd like to try the stock X prop on my turbo ski.

    Very nice gains.

    On # 2 did you mean 15/22 prop or was 19/22 correct? If it was a 15/22 when did you get your prop?

    Did you have a bone stock run to compare the difference in stock air location the the 4 inch?

    I was thinking about your boost numbers tonight as i dont have one installed on the x yet.
    I figured we would get more boost from the X charger, and I realize there are alot of variables, and that the X will flow more air which is not indicated by psi, but they still seem low.
    Anyone else have thoughts on those boost numbers?
    Funny thing is even with boost being low, good speed. Hum,
