    Every Turbo'd engine Ive had really performed with a load, I would be very curious to see gains on a higher pitched prop.

    Nice build

    Thanks but wouldn't that drop my rpms more ? Say if I change from a 15/23 and go up to a 15/25 I would lose an estimasted 400rpms. I would need to add more power/boost to pull it.

    I saw my gps reading was about the same speed as my last run and i had a base number to go off of before i installed Jim's cut.
    I went back to the ramp really quick and installed the plate just as i receied it, NO SHIMMING, just straight bolted it on and had went out and hit a new top speed of 82mph at 8180 Rpms 17psi boost. That's a 2 mph gain for a simple cheap bolt on mod. I bet i can get more speed out of it with a little shimming. Temps were 86degres with 68% humidity

    Ordered a manual boost controller to turn the boost up a few pounds and it should pull the rpms up a tad also.

    Received my manual boost controller last week monday to turn the boost up. Going up to 19-20psi max. whatever it takes to bring that 15/23 prop up to 8500rpms. I know I can just pitch the prop and run lower boost but I love the pull!

    In the middle of dodging hurricanes left right an center. Still haven't had anytime to install it and get some testing done.
