    2012 Nitro Z8 setup

    When I first bought my Z8 new in 2014, it topped out at about 75mph with a 250 Pro XS and a 26P tempest plus. Now that I've put dual Talons and another battery in the back I'm taking forever to get 68mph out of it and its slower out of the hole. Question is, should I raise or lower the JP after putting all of that weight in the back? My prop has since been worked by mark. I used to have all PVS plugs in and now I have all but 1 out to get a good hole shot.

    Need P2P measurement (Prop shaft to Pad). Also RPMs at WOT.

    Also, if you have a manual or hydraulic plate. I have twin Blades and a hydraulic plate. I will, at times, lower the JP a bit to get out of the hole quicker. Once on top, I make adjustments to the conditions. I will add I rarely race around at WOT.

    Has ur rpms dropped? Loosing lift? Reading again u have added close to 200lbs, id come up just a little. May want to consider playing with the pvs plugs.

    I ran my Tempest on 17 Z21 at 3.25" below.
