Speed penalty for not using h-shifter?

Discussion in 'Chit Chat Room' started by Guybrush Threepwood, Oct 26, 2014.

  1. Kunos can you please confirm the penalty for using paddle shift in a H-shifter car?

    It seems with the latest update there is a huge difference in straight line speed. I've noticed this in the BMW E30 DTM and Lotus Elise SC so far. I would hazard a guess of at least 0.5 to 1 second per lap between using H-shifter vs. paddle-shift in cars that are stick shift in real life.

    Anyone else notice this?

    Thank you.

    Kunos have always said using a paddle shift in a stick shift car is slower. It encourages people to use the correct hardware.

    It's only by a tiny bit though, not 0.5sec per lap. To lose 0.5sec there must be something else going on.
     
  4. I'm hoping someone can test the difference. Not everyone has access to a H-shifter and even less have access to one worth using, so the penalty seems excessive. I can understand 1 or 2 tenths, but I am almost certain it is closer to 1 second depending on the track.

    Is there any way you can tell if a car is a stick shift or paddle?
     
  6. AFAIK there is no added penalty, the only advantage you have is that proper use of an H shifter (proper!) is faster than using paddles in H shifter cars, because when AC does the shifting maneuvre by itself it takes into account some fixed shifting times that a good driver may beat doing things by her/himself.

    I don't notice any speed penalty in comparison to drivers who do use H shifter
     
  8. It would be easy for someone to test that had a H-shifter setup... do a drag session on the longest strip so you get to top gear and then just flick between paddles and H-shifter.

    Would something like this settle the debate?


    Exige V6 with 100% default setup.
    Powershifting in both. (full throttle)
    Synced at the 100m point to eliminate any human error.

    I realize just one repetition of the experiment does not provide any indisputable data, but at least it proves that speed penalty on paddle shifters is minimal!

    Looks dead even to me.
     
  11. The timing seemed to be a lot slower for the paddles on the split. What was the overall time with both starting from as soon as the lights go out. It looks like you waited a while to take off with the paddles???

    I think I've done this test once before. Ur eyes don't do you justice. The shift light on h shift comes on much sooner. And you need to do something like 5 runs in each mode. So I settled at 0.05 difference per shift up.
    That will make a minimum of a 0.5sec on a lap. But on most tracks its more like a second difference. And since RC it looks like kunos went mad and this difference is now doubled. Maybe I ought to repeat this test.

    Wouldn't the biggest difference be on downshifts? I'm not sure if you can disallow automatic throttle blip online, but that would probably be a big disadvantage for paddle users. Or?

    Nah, not as much as upshifts on uphill. Take sc2 on imola. It takes a long time without manual clutch.
    And sc3 imola too. Ur going 2nd to 4th or 5th gear twice from low speed. Takes at least .3 in that sector.

    Plus on turbo cars it doesn't keep turbo boost full. So that looses further more time.

    Its a shame. My clutch pot bone down and now I'm stuck with kunos clutch too.

    I only let timing app on to show I didnt speed up any of the vids.
    I launched when I was comfortable, not on a time mark, to remove human reaction time. Otherwise I would need many more repetitions to get any actual, trustworthy data.
    That's why I synced them so they both cross the 100m sign simultaneously, and not at launch.

    Having said the above, there IS a time penalty, but as Niki also mentioned, it's really minimal!
     
  16. I did notice online against a guy I race with in my league who uses H that each time there was a shift up for both cars at the same time his car would jolt ahead of mine. Only noticed it since RC 1.0 though.

    And a top speed comparison.



    This time I synced them at the 2000m point.
    Also changed my start to be more consistent.
    While it is obvious that they both cross the line with same top speed, so no handicap there,
    it is also obvious that paddles get a head start, proving they are indeed a bit slower.

    What I forgot to mention before is, while I agree with Niki on the 0.05s difference, I do NOT agree on the 1 sec per lap comment.
    That is if you only consider shift times.
    But on a lap there are many more factors that influence speed, like for example easiness of gear shifts.
    With a shifter it's alot harder to shift, while miss-shifts are also a considerable possibility, while with paddles you have perfect shifts every time!!

  18. Just look at it as a challenge, guys. Half a second over a single lap really isn't a big deal.

  20. Yep, did a test run using the F40 - 10 runs with and without H shifter - and with the H shifter it was 2 tenths faster over 1000 metres. That was 3 gear changes. :/

    I tried with the E30 DTM but it seemed to bog down off the line without the H shifter when dropping the clutch so it was much slower.

    It's a shame people that can't use the H shifter for various reasons are at such a disadvantage.

    I have no idea if h shifter is faster response or not bu i just HOPE paddle users get a good penalty. Otherwise, why would i kill myself using the hshifter and heel n toe over a 40min- 1 hour race , risking many mis shifts and even spinning the car due to failed heel n toe while the paddleshifters got it easy, no, way MUCH easier.
