This is a thread-topic which borders on the Technical Forum or the Racing Sim-Forum, but I will leave it here.
Recently I bought a wheel with stick-shift and three pedals, and in rFactor I've installed several mods to make stick-shifting with clutch as realistically as possible (for example: a neutral-stall when you depress the clutch insufficiently).
While I am enjoying this (and trying to learn heel-toe), I kind of get confused about the technical history of stick-shifting in racing. Playing realistic F1-mods on rFactor (for example the exemplary F1 1991 historic mod), I was led to believe that synchromesh gearboxes only left F1 after the semi-automatic flipper-wheel operated gearboxes of the mid-90's. (About which Nigel Mansell said he thought it was slightly inconvenient to have to go through the gears instead of just selecting the gear he needed).
Then again, I read somewhere that Colin Chapman already secured synchromesh gearboxes for his Lotus F1-cars in the early sixties... and then I read this quote from Mark Donohue's book: The Unfair Advantage:
Walt drove the first two-hour stretch. When it was my turn, he came in and told me that the clutch linkage was out. It wasn’t possible to disengage the clutch at any time. I thought, “Oh ****! Now what?” He must have seen the panicked look on my face, because he got right to work explaining how to drive without a clutch. I could get going by using the starter with the car in gear. From then on I had to shift by matching engine rpms with the throttle. To upshift, I put pressure on the lever while still at full throttle, then let up on the throttle for just an instant, and it would slip into the next gear. The three-four shift was a little harder, because I had to move the lever laterally in the gate and match engine rpms better. Downshifting was somewhat like double-clutching without the clutch, with a little blip in neutral.
That would indicate a Dogbox, and not synchromesh, right?
To cut a long story short: when did double clutching become unnecessary in most race-cars? And did, say Jim Clark, go through the gears or did he just, as Dear Nige, just select the gear he wanted to be in for the next corner? And perhaps did not even use the clutch?
