    Default Slipper Clutch?

    Thoughts? Would assume that it would be more forgiving for downshifts but weighing some loss in throttle steer.

    ...also hated losing brakes and CVT clutch freewheeling into the danger zone. Not saying you shouldn't prep better but sometimes stuff happens.

    Default Clutch

    Most of us are not using the clutch during the race. Slight lift to up shift and a blip of throttle to down shift while braking.

    I tried to clutch my 1st few races and no clutch is much smother and faster for me.

    Are blippers not allowed in F600?

    They are not and we have to do it manually. No devices is allowed to help us shift. They say it's to keep class cost down.

    Correct only mechanical shifting allowed. No computer or ignition aids are allowed.

    Well JohnPaul, if you're not reading between the lines, electronic/computer blippers are outlawed...but if you make a mechanical one...

    Jay care to share your version yet? I saw you guys were waiting on testing.

    Whether or not you intend to use a clutch after leaving the grid, the slipper clutch, I would assume, would still functions to negate the back drag from a slower engine rpm as in engine braking...or hitting a wrong gear...or assisting in downshifting. In bikes, it's supposed to eliminate wheel hop on aggressive deceleration/down shifting techniques. It apparently does this by separating clutch discs when engine back pressure is induced.

    Wasn't sure how many in the F6 crowd had experience with both set ups yet. Maybe the DSR/P2/FB folks who have been running bike motors for a few years can chime in.

    I can see where some might like the slipper clutch and some might prefer to run a standard motorcycle clutch basket.

    Hmm interesting. I thought it was like p2 where you can't use any type of electronic shifter but can use an electronic blipper. You can always use the Dr.blip that Jay makes

    If I'm not mistaken, a slipper clutch is mechanical not electronic.
    It just reduces "back torque".
    Do F600s get axle hop? Or is it just to reduce drop throttle oversteer?

    Your right, it's mechanical. The wheel hop was on bikes, I don't know of wheel hop in a F5, P2 or FB. It would affect rotating the car...good and/or bad. That's kind of the question...is it bad enough to eliminate or would one prefer another tool in their driver arsenal.

    I've been out of the seat for a while but ran F5's with the CVT. You could throttle steer in some situations but it was more of a subtle rotation from unloading of corners kind of like a hanging curve ball rather than something you could control with the rate of lift and catch of the throttle. Mind you, I know it can produce a snap spin if not on top of it but didn't know if the pros of possibly helping with downshifts overcame the use of more responsive (or threatening) throttle steer.

    Many of the newer bikes have the slipper clutches. I was just curious of those that have run both if they had a preference.
