    F1 shift times
    - anyone got a decent video showing shifting and tacho in a 355-F1
    - so as to gain a feel of its shifting responce.


    My point of reference is probably unfair, given that I race a CN car that has paddle shift on a sequential gearbox. So it's the next best thing to instant up or down, but for the road everything I have is manual. I now have a weird desire to get a 355 with F1 but haven't been able to try one yet.

    So I just test drove a 575 with F1 and ..........
    it was horrible !
    so slow that an auto box would have been better, in fact i put it in auto just so it would be less annoying. and yes it was in sport mode.

    I'm not looking for silky smooth, if anything i want it to be brutally fast, especially on downshifts. The key seems to be my perceived delay between the micro switch click and the gearshift actually happening.

    Does the 575 give a fair indication of the shift on a 355 ? (please say the 355 is much much faster) ?


    cheers.

    Haggis, have you driven an F1 before? The box adjusts its speed to the manner in which you're driving. Drive relaxed and the box will shift so, drive aggressively and the box will give you very brief shift times. Not saying that the F1 on my 575M is Formula 1 fast but when I'm really hammering it, I can't imagine wanting faster shift times.

    I believe the 575 is drive-by-wire where the 355 has a mechanical linkage. Downside is no throttle blip in the 355 but the shifts are virtually instant from when you pull the paddle vs. the early drive-by-wire cars where there is a slight delay. Try one and see.

    355 F1 (in sport mode, over 7k REVS) shifts so fast you would think you neck will break. IIRC, it's around 200ms

    I agree 100% - - Mine shifted very fast when you were on the throttle

    Mine shifts fast enough that it almost seems like something is going to break.

    It shifts as fast as a drag bike with an air shifter.

    The shifts in my 355, if I'm in the throttle, chirp the tires and feel like something is going to break. I love it.

    Maybe you got a bad 575? F1 was not exactly running flawless on Ferraris in general. It would be very unlikely that in 5 years of F1 development Ferrari would make the next gen F1 slower. You want fast go modern DCT or at least BMW SMGlll at 65ms. Tuned corvette C6 slushboxes are claiming 100ms. The early Ferrari F1 were 200ms all the way into the 360 until the CS tune took off another 50ms to 150ms. They all shift fastest in the upper RPM range. Problem you might have with the 575 is that the car is so fast with so much horsepower and huge torque that it is difficult to test max shift speed and not be in reckless driving territory and you have to shut the traction control off too or that nanny will sense wheel spin and curtail your fun and your shift speed. So take it to the track.

    Ferrari quote 150ms in its fastest mode.

    As already said, it depends on how you are driving the car.
    When you are just cruising around the shifts are quite slow (but still faster than a manual box), when you are hammering it they are pretty fast.

    Having said that, compared to what you are used to it will still feel painfully slow.

    I recently spent half an hour in a 458 Speciale and the thing I noticed the most was how instant the gear changes were.

    Getting back in my 355F1 after that....

    Many thanks to all.

    to answer a few questions...
    1. Not driven a 355-F1 before, which is why I asked.

    2. 575.
    i did give it a few 1st(rolling) to 3rd gear WOT runs, and yes it produced the head jerk and all that.
    This 575 seemed well maintained but who can tell if the F1 was operating at it's peak. But there was a noticeable delay between paddle click (cut in power) and the gear being full engaged, which is where the head jerk comes from.

    3. I appreciate that the F1 system is operating a manual box with a clutch so it will never be sequential dog box fast.

    4. 355-F1
    It is the fact that the 355 implementation is still so "manual" that interests me.
    Managing the blip was the attraction.


    Nothing for it, I'll have to ask an acquaintance if i can try his 355-F1.


    thanks.

    so why didn't you ask your acquaintance first?
    remember that the technique is from 20 years ago so nothing in comparison to a 458.
    but to me still amazing if you consider when it was designed.
