    When is it a good idea to switch to open loop?

    Hoping for 81mph this weekend. Not many mods, my tune, air filter, repitched prop, Fizzle and upgraded tubes.

    Winter I will be changing the springs and retainers to spin a little more. Adding a Solas SXX prop.

    Should get that mph.

    Open loop is one of those. Mods that will help with sustaining speeds and imo prolong the life of the engine by keeping it cooler, but that's my opinion. I would say once you start revving it up open loop should be done.

    JP Racing is flashing 300's and getting 81+ on completely stock skis. With some simple mods added to that you could see 85 easy.
