    Speedfreaks pump shoe insert

    I am still in tuning stages and looked at my grate and noticed that there is a pretty big lip in the pump tunnel where the pump shoe is. I was wondering if this is normal or did I install it wrong. Pics are hard to see, and yes i am getting rid of the worx grate and going to the R&D or Riva, havent decided yet... along with the rideplate mod...

    I am at 72.9 mph @ 8100 rpm Think i should be faster, going to install a bellow band as well.

    Any ideas?

    pump shoe insert..

    looks good to me from what i can see in the pic...... i would go for the riva grate if your looking for the best top speeds.

    I'll be honest with yah man, that riva grate is cool for speeds 75 and below but once you get higher that ski will have alot of bounce and you'll want everything to keep it under control. I was goin 79 switched to r&d and it was like night and day. Also the riva's have a tendensy to break the center bolt hole under extreme load. So the riva maybe be just a tad faster but it won't show it without the ski being able to stay hooked up.

    I agree I have found the R&D grate is 2-3 mph slower but well well worth the speed loss.

    The ski runs great, but there is speed loss somewhere. I am in pretty smooth water most of the time.

    I run the riva grate at 85+ without a problem. I am however running an x-rideplate that bolts to all three holes in the grate for support. In your case a girdle will work just as well.

    When you installed the RE's did you align them with the bottom of the hull in the rear or did you leave it to where the hook in the hull is hanging down further than the blockoffs? The hook in the hull should hang lower than the blockoffs and the blockoffs should be inline with the rest off the bottom with a straight edge.
    Also, it may just be me but the shoe protector is sticking up a bit more than I would like.

    When I put the RE's on, I used a straight edge and they extend the original hull line. I was thinking maybe the back of them should be higher letting the bow rise more... I was looking at that last night...
