Correct Shifting Technique?
Posted Sep 12 2013 - 02:02 PM
I'm confused. What is the correct way to shift gears in a 1960s Formula 1 car?
This is a subject where it seems it is very difficult to get a correct answer. There are many "experts" on forums and many I'm sure don't know know what they are talking about while others give contradictory information. Therefore I thought I would ask here as you lot seem a lot more mature than the kids on iRacing etc.
I have been doing some research and it seems F1 cars from the 60s (as well as other Formula-type cars all the way up to the present day) use a gearbox know as a "dog-box" - sometimes "crash-box". This is a name derived from the "dogs" inside the box that select gears. One of the properties of this type of gearbox apparently is that you don't always need your clutch when selecting gears. Is this true or false? The reason I ask is because in driving simulators I like to do things in at least a semi-realistic manner. To me this is part of the enjoyment. I bought a clutch and an H-shifter for this exact reason.
I have read contradictory reports. Some people say you don't need to use the clutch AT ALL apart from on the start line, some say you don't need to clutch on upshifts but DO need to do so on downshifts. Is there anyone here who can give a CORRECT answer?
My second question: does GPL use an auto-blip? If so, is there a way of turning it off?
Thanks in anticipation.

You can change gear on any car without using the clutch - it's just a matter of matching the revs to the roadspeed. Changing up only requires the engine revs to drop to the next gears road speed. Changing down requires a blip on the throttle, and is less easy to manage precisely. When straight ( dog ) gears are forced to mesh at the wrong speed, a strain is put on the drivetrain, and things can break. So clutch use is more common on downshift. And I imagine endurance racers use the clutch up and down. Double declutch is a more complex version of this, and used to ensure smooth changes.
This is 2nd hand information, as I've not raced 'doggedly.' One of our real life racers, might wish to correct me, if my assumptions are misplaced. And a clutch enhanced wheel user, can tackle your blip.

But after watching hundreds of onboard videos of the 60th cars I didn't found one car with it.
So I would recommend to use Your H-shifter and clutch with GPLshift and forced clutch on to have it " ... in at least a semi-realistic manner.).
I see no historical reason for shifting without clutch and it will lead into trouble in some leagues because it causes an advantage
during acceleration compared to the default GPL paddle / keyboard shifting with an artificial delay of around 0,222 seconds.
Some leagues force You to use a tool that adds an artificial delay also to the H-shifter without clutch.
In this video You can see how Graham Hill shifted. Sometimes so fast as if he didn't used the clutch.

Nowadays modern cars don't need this apparently but I do this sometimes anyway, especially when overtaking (dropping a gear to pass the car in front). I drove a MG Midget with a dog box and struggled to change down, but I'd only just started driving then.
I've never driven a car in competition but I felt I was quite a competent driver.

For the record last week I did an experiment in iRacing. I turned auto-blip on and off to see the difference. With it ON you can definitely see a change in the way the rev needle jumps - it definitely jumps higher and the revs seem to linger for a while.
Now, in GPL the needle behaves like it does in iRacing with auto-blip OFF. Is the blip hidden from us in some way? Unfortunately I'm not a good enough driver to be able to tell just by doing some laps.

I am using shifting_behaviour_1 with a Thrustmaster THRS shifter, for the record.

Ah, thanks. No wonder they call you the answer man!
