    RPM/Speed Loss in Summer

    SHO owners, what kind of RPM/Speed loss are you guys seeing from Winter to Summer? At WOT I'm running approx. 74/6200 below 50 degrees and 71/5900 above 80 degrees with similar loads. Just trying to see if that is normal.

    That sounds about right. Some guys (myself included) will run a pitch lower in summer months to help holeshot and keep RPM up, might even get a mph or so back also

    Yep I'm seeing approximately the same results. 5900-6000 rpms in winter at 86-87 mph. 55-5600 now with the heat and humidity. 82-83 mph.

    I was hitting 43mph with the SHO in cold weather. Past month I've been struggling to keep 40mph

    That with the Scorpion? Have you tried dropping some pitch to get some rpm back? I dont like luggin mine @ 5500 WOT, want to be able to turn as close to 6K as possible when I want regardless of temp/humidity/load

    I have a 27 t-1 being repaired. I will try it and tune it to get my rpms back up. I also recently added power poles and I know they are taking away some speed and rpms too.
